The commissioning of the Land van Cuijk

Wastewater Treatment Plant (WWTP) for

cogeneration and partial fl ow treatment on

March 5, 2015 has considerably reduced the

plant’s energy consumption. The changes have

also increased the effi ciency of the reprocessing

of the combined gas stream as well as the

recovery of phosphate as required by the Chain

Agreement regarding the Phosphate Cycle. The

project was developed through collaboration

between Attero and the Water Board.

Attero has a plant that converts landfi ll gas into

energy via a Combined Heat and Power (CHP) plant.

The leachate is partially purifi ed and then fed to the

WWTP. The water rejected by the WWTP is now

being pumped to the phosphate extraction plant

before joining the leachate for de-ammonifi cation.

The construction of this bypass treatment plant

for phosphate recovery and nitrogen removal

together with the combined processing of gas

and wastewater has increased the sustainability

of the plant and has reduced its operating costs.

Logisticon Water Treatment designed and built

this bypass treatment plant in collaboration with

NuReSys and Grontmij. The plant comprises

a stripper for pH correction, a struvite reactor

for the recovery of phosphate according to the

NuReSys® principle, de-ammonifi cation with

Demon® installation according to Grontmij’s

design and a plate separator.

Arisu in Çivril, Turkey, is the production

facility of Ariza, a company based in

Helmond, the Netherlands. This plant

produces apple concentrate. The

production process generates a large

volume of wastewater that must be

treated.

Because the existing facility did not

have suffi cient capacity to meet the

demand resulting from the increase

in production, Arisu decided to update

the facility. It chose to employ physical/

biological treatment to meet Ariza’s

high quality standards. Last year, two

large lagoons were renovated and

one lagoon was equipped with four

aerators provided by Logisticon Water

Treatment. Due to the presence of,

among other things, polyphenols

from the apples (pigment), it was

not possible to meet the discharge

requirements. Therefore, last year

Ariza contacted Logisticon to address

this specifi c problem and for a start

hired a DAF fl otation plant.

The plant now performs perfectly

through additional dosing of ferrous

chloride and polymer into the feed of

the installed DAF fl otation plant. After

fi ne-tuning the purifi cation process,

the facility was fi nally able to meet the

discharge requirements at a capacity

of 40-50 m3/h. The fl otation plant was

eventually purchased.

Mobile MBR extraction unit for AtteroAfter a fi re at Attero in Landgraaf, Logisticon Hire was able to deliver a temporary mobile

membrane bioreactor (MBR) extraction unit to the site within a week. This MBR rental

unit proved to be a good experience because it became clear that it reduced the energy

and chemical consumption considerably when

compared to the old plant that had burned down.

In particular, the cleaning of the membranes could

be kept to the bare minimum.

The MBR has a capacity of 5 m3/h that can be

increased if required in the future to 10 m3/h.

Thanks to Logisticon’s expertise, Attero Landgraaf

has also found a defi nitive solution to eventually

process leachate using an MBR installation. The

new MBR plant contains an extraction tank for two membrane modules, a permeate

tank, measuring equipment, valves, pumps, piping and controls. The whole process is

integrated into an insulated 20ft container, which also includes a railing on top, enabling

safe working at height and a higher extraction tank with removable hatches.

The advantage of this implementation is

that the plant is tested completely and as

such supplied ready to plug & play. This

means that it can be installed on-site with

the minimum of effort and it can start to

operate immediately.W

Croda starts to reuse wastewater

After nine months of extensive trials,

Logisticon Water Treatment built a

completely new installation for Croda.

This installation employs ultra-fi ltration

(to remove all the suspended solids in

the wastewater) and reverse osmosis

(to remove the salts and to reduce

the hardness of the water). This

ensures that the water supplied to the

demineralization process contains far

less salt and bicarbonate enabling a

90 percent saving in the consumption

of caustic soda and hydrochloric acid.

Construction of this plant required

an investment of around two million

euros. The Croda plant is expected to

pay for itself within six to seven years.

Croda based in Gouda, the Netherlands,

is a producer of specialty semi-

fi nished products based on natural

oils and fats. It launched its innovative

membrane fi ltration plant in May 2014.

This plant purifi es the wastewater

the company produces for reuse,

after demineralization, as cooling

water, process water and steam.

This reduces the annual groundwater

use by 500,000 cubic meters, greatly

reduces the use of chemicals, reduces

CO2 emissions considerably and also

greatly reduces the amount of salt

discharged into the surface water.

Supplying membrane installations for HumViThe Vitens drinking water company is very progressive in the fi eld of recycling

waste streams. The company won the Aquatech Innovation Award in 2014 for

its Humvi technology that recycles 100% of waste streams resulting from the

decolouration of drinking water. The HumVi technique is an effi cient application

of ion exchange membrane technology in combination with various membrane

techniques that makes it possible to transform groundwater into perfect drinking

water.

Logisticon Water Treatment helped Vitens to

design and realise this membrane technology.

This latest technology operates in batch mode

at 50 bar to concentrate and scrub the humic

acids from the water with the use of special

nano-fi ltration membranes, which were in the

past responsible for the colour in the water. In

addition, Logisticon has built an 80-bar RO system

to convert the residual water from the fi rst unit

into a concentrated salt stream so that it can be

reused in the ion exchange regeneration.

The humic acid produced is upgraded to a product that is

now being used in the agricultural sector as a plant and

soil conditioner. Other applications such as replacement of

antibiotics in animal feed are still being investigated.

Reverse Osmosis Plant 50m3/h and 40 m3/h for Induss II in GhentCommissioned by Induss, a Belgian joint venture between Antwerp Water Works (AWW)

and Farys (the operational arm of the municipal umbrella organisation for water supply

in Flanders - TMVW), Logisticon Water Treatment has been tasked with the expansion

of Reverse Osmosis (RO) capacity at an existing manufacturing location. This Induss II

location, near the Rodenhuizedok in Ghent, produces four different qualities of process

water from surface water (supposedly dock water) for businesses in the neighbourhood

and ‘mobile pick up.” Because a new customer was connected and thus the need for

cooling water increased, Induss II needed to expand its production capacity.

The capacity was increased by a new RO plant that is quite special in so much that it can

work in both single- as well as double-pass RO mode. This results in a system that can

produce either 90 m3/h (50 + 40 parallel) or 40 m3/h of water when operating in double-

pass (serial) RO mode.

Furthermore, in this RO plant, which is constructed on a single robust stainless steel

frame, Logisticon has also been able to include ‘Low Fouling’ membranes with enlarged

spacers. This minimizes the cleaning (CIP) frequency.

IOI Loders Croklaan, which makes

food products based on vegetable

oils and fats, has for many years been

‘ahead of the curve’ in the sustainable

development of its products. The

building of a wastewater recycling

plant at the production facility in

Wormerveer marks the next level in this

development. Currently, wastewater is

still discharged into the sewer system;

however, the goal is to reuse it for

boiler water and demineralised water

for palm oil fractioning and refi ning.

This will also lead to a reduction in the

wastewater discharged, a reduction in

the salt discharged, thanks to the use

of softeners, and the procurement of

drinking water.

Logisticon Water Treatment won the

contract for this turnkey installation,

which will be commissioned

and integrated with the existing

demineralized water system.

The water will be purifi ed using a

membrane bioreactor (MBR) based

upon the Berghof BioPulse® concept,

followed by reverse osmosis (RO) that

will clean the water to the required

quality for reuse. The installation,

including a biological 600-m3 tank,

has an average capacity of 360 m3/

day. Loders Croklaan also chose

the BioPulse® concept because of

its lower power consumption when

compared to conventional MBR

systems. The installation is expected

to be operational in April 2015.

Themista® and Ephyra® are two new technologies that are able to reduce the amount of

sludge released during wastewater treatment and maximize the production of biogas.

These innovative sludge digestion technologies were developed by Royal HaskoningDHV

and are recognized as being highly effi cient and robust with lower operating costs. Both

technologies can be used to pre-treat sludge in existing digestion installations; e.g. in

wastewater treatment plants where additional sludge has to be processed or where there

is a goal to extract more energy from the sewage sludge. Ephyra® can also be used as an

independent digestion process. To determine the full potential, the next phase is to carry

out a pilot study under practical conditions. With the results, it is possible to establish

business cases, within which the technical and fi nancial feasibility of the technologies can

be further substantiated.

The pilot study is being carried out at the Kralingseveer sewage treatment plant in Capelle

aan den IJssel and at the WWTP in Tollebeek, it is fi nancially supported by the National

Offi ce for Netherlands Enterprise Agency (RVO). The project is being led by a consortium

consisting of STOWA, Hoogheemraadschap Schieland and Krimpenerwaard Zuiderzeeland

Water, TU Delft, Logisticon Water Treatment, Endress + Hauser and Royal HaskoningDHV.

The Nieuwegein Hoogheemraadschap

Stichtse Rijnlanden (HDSR) wants its

WasteWater Treatment (WWTP) plant to

start producing electricity. Previously, three

large on-site aerators, which consumed a

huge amount of energy, were used to aerate

the wastewater. In order to design an energy-

effi cient plant, HDSR devised a formula that

included the construction and energy costs.

The effect of this formula on the design has

been extensively studied by Logisticon and

has led to even more energy savings than

expected. The UAV-GC contract is therefore

proving to be an ideal stepping stone to

achieve the power generation aim; it uses

the creativity of the experienced designer

in the form of Logisticon Water Treatment

within the framework as defi ned by HDSR.

An additional hurdle that fi rst had to be

overcome was that the aeration tank could

not be emptied. Therefore, the aeration

grids needed to be submergible and also

retrievable for inspection and maintenance.

Logisticon Water had already built a de-

ammonifi cation plant (Demon®) for the

WWTP in Nieuwegein. This plant removes

the nitrogen from the wastewater (see

also Logisticon Tour 16). The water board

chose this new technology because of its

ruggedness, low investment and low power

consumption. These two projects will

contribute to the construction of an energy

plant for HDSR.

Our own pickling plant has met some of

our goals including a reduction in transport

movements, which has reduced our energy

consumption and also our CO2 emissions;

three days have been gained because

the stainless steel parts can be pickled

and passivated completely automatically.

Quality control and the quick response to
