INDUSTRIAL WASTEWATER TREATMENT

We help industries setting new standards in responsible water management. Our solutions include aerobic and anaerobic wastewater treatment enabling biogas production as well as membrane technologies allowing water reuse, reducing the plants energy and water footprint.

Our track record counts more than 400 references for water treatment in different industries.

Choosing the appropriate treatment process is only possible when characteristics and specific problems for each individual wastewater are known in advance.

AEROBIC WASTEWATER TREATMENT

Aerobic plants produce a high-quality effluent. The organic pollution is transformed into carbon dioxide and biomass by aeration (aerobic). Our aerobic wastewater treatment plants are designed to eliminate not only organic pollution (or BOD) but also nitrogen and phosphorus.

ANAEROBIC WASTEWATER TREATMENTduction

When organic concentration in wastewater is high, our anaerobic wastewater treatment technologies become a valuable alternative for aerobic treatment, since an energy-rich biogas is produced as a by-product during the process, allowing the production of steam or electricity.

An optional aerobic post treatment step combines biogas production with a low sludge and high-quality effluent production.

MEMBRANE BIO-REACTOR

Where space is scarce, a wastewater treatment plant’s footprint can be limited by replacing the sedimentation step by a compact membrane water/sludge separation device, which produces a high-quality effluent and reduces the volume of the bioreactor.

Since the filtrate cannot pass the membranes, it is virtually free of suspended solids and bacteria and ready for reuse or for further treatment by reverse osmosis.

Membrane bioreactor concepts

Membrane bio reactors can either be placed externally, i.e. in an external loop to the bioreactor) or they can be submerged in the activated sludge, i.e. in the bioreactor itself.

Both membrane bioreactor concepts have their own advantages and they have their own range of application.
