CHAPTER-1

INTRODUCTION

1.0 INTRODUCTION

Modern Industrial Estate comprising of about 620 acres was set up at Kundli by the

Haryana govt. on the side of NH-1 at Haryana-Delhi border to give relief to Delhi

from its increasing industrial pressure. Plots of various categories ranging from 10

Marla plots to two acres have been carved out. In this area different industries related

to footwear, iron & fabrication, plastic goods, pharmaceuticals, chemicals,

confectionary / food processing, auto mobiles ancillaries and electronic & electrical

good etc. have been established. There is an existing CETP of capacity 4 MLD which

was constructed about 15 years ago on approx 28,105 sq. m (7 Acres ) of triangular

shaped land in Phase IV, HSIIDC, Kundli to treat the effluent of this area (Phase I to

IV). The outlet of the treated effluent is being disposed off directly in the drain

running besides the CETP.

Now with the increase in industrial activities in the area (Phase III, IV, IV sector-56),

the quantity of effluent at the CETP is expected to increase and hence it has become

necessary to increase the capacity of the existing system from 4 MLD to 10 MLD.

The proposed up gradation is coming up within the same premises.

Total estimated cost including O&M, Power, Chemicals, Sludge disposal and

Departmental Over head expenses will be Rs. 45.86 Crores and Total Estimated

capital investment will be Rs. 21.02 crores for the proposed CETP up-gradation.

The project falls under “item 7(h) of Schedule of Environment Clearance

Notification dated 14th September, 2006, i.e. Common Effluent Treatment Plant,

under Category –“B”. However, due to presence of Haryana-Delhi interstate

boundary at a distance of 2.3 Km in S direction the proposed project will be treated

as Category “A” project.

As per the EIA Notification and subsequent amendments, “if any of the existing or

proposed member units of the said CETP produces or proposes to produce any product





requiring environmental clearance, then the CETP shall need environmental

clearance”. Proposed CETP involves the treatment of waste water from the

Metallurgical Industries which requires Environment Clearance. Therefore, the project

requires a prior environmental clearance from MoEF&CC, New Delhi.

M/s HSIIDC has retained the services of Gaurang Environmental Solutions, Jaipur to

undertake Environmental Impact Assessment (EIA) studies for assessing the impact of

the Up gradation of existing CETP from 4 MLD to 10 MLD capacity on various

environmental parameters in the study area and to prepare an Environment Management

Plan (EMP) for negating the adverse impacts of the project to obtain Environment

Clearance from MoEF&CC, New Delhi.

The application for prior Environmental Clearance (Form-1) was uploaded on dated

07.03.2019. Project was consider in 40th Expert Appraisal Committee (Infra-2) (S. No.

40) Dated 23rd April’ 2019. Project was reconsider for Terms of Reference in in 43rd

Expert Appraisal Committee (Infra-2) (S. No. 43.3.10) Dated 20-22 August’ 2019 and

the project was granted with standard Terms of Reference vide letter no. F. No.10-

23/2019-IA-III Dated 31st October 2019 by MoEF&CC. Copy of Terms of Reference

is enclosed as Annexure I. Baseline studies for the project were carried out during

December’2018 to February’ 2019 (winter season).Public consultation for the project

has been exempted as the proposed up gradation of existing CETP area falls under the

notified industrial area. The industrial area notification gazette is enclosed as

Annexure -VII.

The proposed up gradation of existing common effluent treatment plant will be based

on physical & chemical treatment for removal of excessive inorganic COD, TSS &

BOD beside removal of color & maintenance of equalized & constant PH & Flow rate

prior to biological process i.e. Activated Sludge process based on extended aeration

principal. That after biological Treatment process treated effluent shall be further

treated in pressure Filter, Carbon filter and shall be disinfected with chlorine before

final disposal for reuse being designed on the concept of Zero liquid discharge.

Waste water thus generated by the associated industries will be lifted through

dedicated pipeline system after meeting the pre treatment discharge standards

prescribed by HSIIDC. Waste water generated from Pharmaceutical and chemical

member industry will be treated by themselves and treated water will be discharge as

per standards prescribed by HSPCB and CPCB. The waste water after treatment shall





meet the discharge standards laid down by MoEF&CC and HSPCB. It has been

proposed by HSIIDC to reuse treated effluent for irrigation, watering of parks &

greens etc. which will require multimedia filtration with Pressure Filter, Activated

Carbon Filter followed by disinfection for removal of coliforms and helminthes so as

to achieve Zero liquid discharge.

The HSIIDC has always taken lead in providing best possible infrastructure facilities

in all the Industrial Estates. Accordingly it has been decided that Disposal works

Common Effluent Treatment Plant & Disposal of Treated Effluent as per CPHEEO

Norms be designed and got executed at site.

This Environmental Impact Assessment (EIA) report has been prepared to provide

information on the potential environmental, social and economic impacts of the

project. It also aims to make recommendations for mitigation of the potential negative

impacts and enhancement of the positive ones. Baseline data generation including

detailed field survey was carried out and potential environmental impacts of the

project activities were identified, assessed and documented. This report has been

prepared as per the Terms of References (Standard ToR issued by MoEF&CC, New

Delhi), EIA Notification, 2006 & amendments.

1.3.4 Project Importance to the Country / Region

Establishment of effluent treatment plants for individual industries especially in the

small scale sector in the various industrial estates in India, to produce the effluent of

desired quality before discharge is not feasible in the Indian context. Firstly, because

it is expensive on both the capital and operating cost front and secondly, there is no

guarantee of performance by the individual industries. Further, the disposal of treated

effluents is also problematic as every individual industry cannot reach the water body

through its own pipeline nor can it purchase land for inland irrigation. Thus,

Government of India floated the idea of Common effluent treatment plant to

overcome these problems. Accordingly Ministry of Environment, Forest & Climate

Change, Government of India instructed the various State Pollution Control Boards to

examine the possibilities of establishing CETP’s in various industrial estates. In

response to the directive issued by the Central Governments, the State Governments

started identifying the various locations for CETP’s. Establishment of CETP has

following advantages:





• Saving in Capital and Operating cost of treatment plant. The Common treatment

is always cheaper than small scattered treatment units.

• Contribution of nutrient and diluting potential make the complex industrial waste

more amenable to degradation.

• The neutralization and equalization of heterogeneous waste makes its treatment

techno-economically viable.

• Professional and trained staff can be made available for operation of CETP which

is not possible in case of individual plants.

• Disposal of treated wastewater & sludge becomes more organized.

• Reduced burden of various regulatory authorities in ensuring pollution control

requirement.

Water is our most important resource. The available supply of fresh water is an

absolute deadline beyond which no community, state or nation can ever go. When

humanity runs out of clean water, everything stops. That is the end of road for a man

and his activities. Saving our clean water is thus a must. When untreated or

inadequately treated waste waters are discharged, these have adverse affect on the

body of water into which these wastes are disposed. The type of treatment of waste

water would depend upon the use of effluent itself or of receiving body of water into

which effluent is discharged. The degree of treatment of waste water would further

depend upon the discharge of receiving body of water. If small quantity of waste

water is discharged in a river or into the sea, the degree of treatment would be much

less than if the same quantity of waste water is discharged into a small stream. When

receiving body of water is already polluted because of discharge of waste into it, the

extent of new discharge of waste into it would be limited.

Waste water thus generated by the associated industries will be lifted through

dedicated pipeline system after meeting the pre treatment discharge standards

prescribed by HSIIDC. The waste water after treatment shall meet the discharge

standards laid down by MoEF&CC and HSPCB. Waste water generated from

Pharmaceutical and chemical member industry will be treated by themselves and

treated water will be discharge as per standards prescribed by CPCB. It has been

proposed by HSIIDC to reuse treated effluent for irrigation, watering of parks &

greens etc. which will require multimedia filtration with Pressure Filter, Activated





Carbon Filter followed by disinfection for removal of coliforms and helminthes so as

to achieve Zero liquid discharge.

EIA for Up gradation of existing CETP from 4 MLD to 10 MLD capacity at Kundli, Sonipat, Haryana Promoter: HSIIDC Limited Chapter-2 Project Description



CHAPTER-2

PROJECT DESCRIPTION

This chapter deals with the technical details of the Up gradation of existing CETP from 4 MLD

to 10 MLD capacity based on extend aeration system, process and technology description and

details of infrastructure.

2.1 TYPE OF PROJECT

There is an existing CETP of capacity 4 MLD which was constructed about 15 years ago

on approx 28,105 sq. m (7 Acres ) of triangular shaped land in Phase IV, HSIIDC,

Kundli to treat the effluent of this area (Phase I to IV). The outlet of the treated effluent

is being disposed off directly in the drain running besides the CETP.

Now with the increase in industrial activities in the area (Phase III, IV, IV sector-56), the

quantity of effluent at the CETP is expected to increase and hence it has become

necessary to increase the capacity of the existing system from 4 MLD to 10 MLD. The

proposed up gradation is coming up within the premises.


Notification dated 14th September, 2006, i.e. Common Effluent Treatment Plant,

under Category –“B”. However, due to presence of Haryana-Delhi interstate

boundary at a distance of 2.3 Km in S direction the proposed project will be treated

as Category “A” project.


proposed member units of the said CETP produces or proposes to produce any

product requiring environmental clearance, then the CETP shall need environmental



requires a prior environmental clearance from MoEF&CC, New Delhi.




2.2 NEED FOR THE PROJECT

Establishment of effluent treatment plants for individual industries especially in the

small scale sector in the various industrial estates in India, to produce the effluent of

desired quality before discharge is not feasible in the Indian context. Firstly, because it

is expensive on both the capital and operating cost front and secondly, there is no

guarantee of performance by the individual industries. Further, the disposal of treated

effluents is also problematic as every individual industry cannot reach the water body

through its own pipeline nor can it purchase land for inland irrigation. Thus,

Government of India floated the idea of Common effluent treatment plant to

overcome these problems. Accordingly Ministry of Environment, Forest & Climate

Change, Government of India instructed the various State Pollution Control Boards to

examine the possibilities of establishing CETP’s in various industrial estates. In

response to the directive issued by the Central Governments, the State

Governments started identifying the various locations for CETP’s.

Establishment of CETP has following advantages:

• Saving in Capital and Operating cost of treatment plant. The Common

treatment is always cheaper than small scattered treatment units.

• Contribution of nutrient and diluting potential make the complex industrial

waste more amenable to degradation.

• The neutralization and equalization of heterogeneous waste makes its treatment

techno-economically viable.

• Professional and trained staff can be made available for operation of CETP

which is not possible in case of individual plants.

• Disposal of treated wastewater & sludge becomes more organized.

• Reduced burden of various regulatory authorities in ensuring pollution control

requirement.

Water is our most important resource. The available supply of fresh water is an

absolute deadline beyond which no community, state or nation can ever go. When

humanity runs out of clean water, everything stops. That is the end of road for a man

and his activities. Saving our clean water is thus a must. When untreated or

inadequately treated waste waters are discharged, these have adverse affect on the

body of water into which these wastes are disposed. The type of treatment of waste




water would depend upon the use of effluent itself or of receiving body of water into

which effluent is discharged. The degree of treatment of waste water would further

depend upon the discharge of receiving body of water. If small quantity of waste

water is discharged in a river or into the sea, the degree of treatment would be much

less than if the same quantity of waste water is discharged into a small stream. When

receiving body of water is already polluted because of discharge of waste into it, the

extent of new discharge of waste into it would be limited.

The project is for common effluent treatment plant to treat the effluent being

generated from the industries located in the industrial estate ((Phase I to IV – existing

CETP, Phase III, IV, IV sector-56 – proposed CETP). Waste water thus generated by

the associated industries will be lifted through dedicated pipeline system after meeting

the pre treatment discharge standards prescribed by HSIIDC. The waste water after

treatment shall meet the discharge standards laid down by MoEF&CC and HSPCB. It

has been proposed by HSIIDC to reuse treated effluent for irrigation, watering of

parks & greens etc. which will require multimedia filtration with Pressure Filter,

Activated Carbon Filter followed by disinfection for removal of coliforms and

helminthes so as to achieve Zero liquid discharge.

2.6 TECHNOLOGY AND PROCESS DESCRIPTION OF COMMON

EFFLUENT TREATMENT PLANT

At present 4 MLD capacity CETP is functional for treated effluent of Indl Estate Kundli

(Phase I to IV). The treated effluent is being disposed off in drain no. 8 by pumping

system through 200 mm dia PVC pipe line. At present, the average inflow is approx. 4

MLD & will reach 5 MLD within a year. Presently, the Indl. Estate sector-38 Ph-I has

fully been developed and in Mega Food Park area, the maximum number of plots are

under construction. The present arrangement will be inadequate and needs to be

upgraded to treat the maximum discharge of 10 MLD.

The existing treatment process which has been adopted for the 4 MLD CETP which is

functioning is Extended Aeration process. The upgradation of the treatment plant has

been proposed using the similar treatment process so that there is a parity with the

existing system as well as the existing structures can be used to 5 the maximum

possible extent. Detailed design report has been prepared using the existing

Equalization tanks, Aeration system and Secondary clarifier system, which will be

augmented with new units which are necessary and compatible with the existing

structures has been mentioned hereunder. Moreover, Extended Aeration process which

is most technically and financially viable treatment process, has been recommended for

adoption as the treated effluent parameters even after secondary treatments meets the

Pollution Control Board norms at the lowest power consumption. The methods range

from physico- chemical to biological & in the latter group from aerobic to anaerobic.

RAW EFFLUENT CHARACTERISTICS

Member industries of CETP will be required to monitor specified quality parameters

and flow rate of the effluent on daily basis and to submit the monitoring data to the

CETP operator on regular basis. Continuous flow meters will also be installed at the

outlet of the CETP to monitor the outlet effluent quantity.

The effluent characteristics of mix type industrial units has been assessed as under for

designing of CETP. It is presumed that most of the industrial unit shall have their own




treatment plants & shall have consent from Haryana state Pollution Control Board to

discharge treated effluent in to the common sewers. The values given in Table below,

are considered in design:

The existing system has structures which needs to be improvised with new structures to

meet the requirement of the CETP.

The adequacy of the existing structures has been checked only those modifications/

additional structures are proposed which are essentially required.

However, the replacement of existing electromechanical equipment’s has been

proposed since the same has outlived its performance period and the material of

construction has been used as Mild Steel which has been corroded.

The details of the structures included in the CETP is given below:

Inlet Pipe: - The existing inlet pipe is of size 800 mm diameter. The invert of the inlet

pipe is 196.0 m. The inlet pipe has been found to be adequate to discharge peak flow (3

times the average flow) at a velocity of 0.7 m/sec.

Receiving chamber:- The existing Receiving chamber is of size 3m x 1m x 5.5 m

depth. The chamber is capable of accommodating flow for 30 seconds. Hence no

additional Receiving chamber has been proposed.

Coarse Screen chamber:- The existing coarse screen chamber is of size 6m x 4m x 5

m deep. It is proposed to convert the existing Screen chamber to mechanical coarse

screen chamber. The present structure can be modified by constructing concrete

partition walls to accommodate 3 nos. mechanical Coarse Screen (2W mechanical + 1

SB mechanical ) suitable for channel size 6.0 m x 1.16 m x 0.7 SWD + 0.3 FB.

Effluent Inlet Sump:- At present there is a circular Effluent Inlet chamber which is

pumping effluent directly to the Equalization Chamber. The size is 10m dia. + 3 m




SWD. The existing size is adequate to accommodate effluent for HRT 10 min at peak

flow of 30 MLD. The Effluent Inlet sump will be utilized to pump effluent to the fine

screen chamber.

Replacement of existing submersible pumps with non-clog submersible sewage pumps

as here under have been proposed: - 417 M^3/ Hr. @ 15MWC, 4Nos. (3W+1SB).

Non clog submersible sewage pumps have been proposed keeping in view the depth of

the incoming sewer and high water table.

Mechanical fine screen, oil and grease trap:- There is no existing fine screen

chamber with oil and grease trap. Therefore a new mechanical Fine screen chamber 3

nos (2 W+1 SB) is proposed with oil and grease trap to accommodate flow of 10 MLD

with 3.0 peak factor.

Equalization Tank:- There is an existing Equalization tank of size 27 m diameter and

SWD 3.75 m. The tank can accommodate average flow of 416.67 m3/hr for 5 hours. It

is proposed to utilize the existing Equalization tank as there will be intermittent

discharge of different characteristics from mix of industries. It is proposed to install air

diffusing system like aspirators in the Equalization tank to enhance the oxidation

process of the pollutants. Thereafter the equalized effluent shall be pumped in to the

flash mixer. Replacement of all existing effluent pump has been proposed in the DPR

as the capacity of the pumps has been enhanced for 10 MLD plant.

B. Chemical Treatment

Flash Mixer:- At present there is no flash mixer is installed. The equalized effluent is

being pumped to the existing primary clarifier. It is proposed to construct a flash mixer

of size 2.55m x1.70m x 1.5m SWD + 0.40m FB. The equalized effluent will be pumped

into the flash mixer for mixing of ferrous alum & lime. It is proposed to convert the

existing Primary Clarifier of 13m dia. and 3.0 m SWD into a Flocculator. The

coagulated effluent from the Flash mixer shall flow into the Flocculator with concentric

flocculation unit after addition of fast settling chemical viz. Polyelectrolyte.

Flocculator:- A separate Primary Clarifier has been proposed to be built besides the

existing one. The same has been proposed because the existing Primary clarifier is

inadequate to handle the effluent of 10 MLD. As mentioned above the existing Primacy

clarifier – 1 no. will be converted into a flocculator. In the Flocculator, the effluent

mixed with ferrous sulphate, ferrous chloride and Lime solution in the flash mixer will

result in formation of flocs. Addition of polyelectrolyte is also proposed to thicken the




flocs. Though a flocculator is designed for 30 min HRT but the existing structure will

provide an HRT of 55 min which will add efficiency to the system. The size of the

Flocculator designed for HRT 55 minutes is 13 m dia. x 3 m SWD.- 1 no.

Primary Clarifier:- A clarifier is a settling zone where the flocs formed at the

flocculator settles. A new Primary clarifier is proposed besides the existing structure to

allow clarification of the incoming effluent. The size of the Clarfication unit is circular

tank of 21.2 m diameter and 3.0 m SWD. This physically & Chemically treatment shall

remove colour, oil & Grease, correct PH, remove TSS at least by 70% & COD/ BOD5

by 50/ 30% respectively.

Effluent Characteristics after primary Treatment.

BOD5, mg/L 360.00

TSS , mg/L 540.00

COD, mg/ L 675.00

C. Biological Treatment

Aeration Tank:- At present there are two nos. of rectangular Aeration tank of size

43m x 13m x 3m SWD. The existing tanks are inadequate to handle 10 MLD effluent.

Hence it is proposed to provide further 2 nos. Aeration tank of length 43m x 22m x

3m SWD. This physically & Chemically treated effluent shall fl
