The Problem

Highly colored wastewater from textile industryHigh concentration of non-biodegradable organics,

suspended solids, conductivity, turbidity and intense color

of the chemical in textile processing will remain on the fabric…..10%

will be discharged in textile effluent 90%

(IPPC, 2003)

m3 of textile wastewater are generated per ton fabric80 -100

(Savin et al, 2008)

Conventional biological system fails to treat textile wastewater

Physico-chemical treatment is available but expensive in terms of chemical and

operational costs

Environmental Regulations (Industrial Effluent), 2009

Colour*Std A – 100 ADMIStd B – 200 ADMI

*Color was not regulated in previous regulation

Our Solution

Hybrid Biogranular System

INSPIRING CREATIVE AND INNOVATIVE MINDS

FeaturesTreat textile wastewater within relatively

short period of time

Simple yet reliable and proven effective (90% COD and color removal)

Use microorganisms rather than chemicals – no chemical sludge, environmentally

sustainable

INSPIRING CREATIVE AND INNOVATIVE MINDS

Basis of Technology

Anaerobic followed by Aerobic stage

INSPIRING CREATIVE AND INNOVATIVE MINDS

Use biogranules instead of bioflocs - higher biomass concentration and shorter sedimentation time

Biogranules function in both anaerobic and aerobic

Hybrid - requires only one reactor – small foot-print

Excess biogranules (sludge) - stored or sold to other treatment plant - potential source of income

WHAT IS BIOGRANULESBiogranules» Developed in the reactor under

specific conditions» Irregular shape with smooth

surface» Size of 2.3 + 1 mm in diameter as

compared to 0.02 + 0.01 for flocs» Dense and compact with

excellent settling property (approx. 80 m/hr)

» Structurally strong

settling (5 min)

Treatment can be completed within 24 hours
