COLSEN

Colsen is an innovative technology supplier for municipal and industrial wastewater treatment, and animal manure treatment. With offices in the Netherlands, Spain and South Africa, and a network of agents across the world, we are able to deliver local support for every project. Depending on your need, we offer tailor made support. This varies from independent consultancy, technology & engineering packages to turn-key delivery of plants or key parts of your installation.

Across our markets, we have some premium technologies that diversify us from our colleagues.

• In municipal sewage treatment we offer thermophilic anaerobic sludge digestion (TAD) for Class A biosolids production, biological biogas desulphurization (BIDOX®) and phosphate recovery as struvite (UPHOS®).

• Also in municipal sewage treatment we offer side stream treatment for nitrogen removal with NAS®-ONE relying on anammox bacteria or AMFER® for nitrogen recovery though stripping/scrubbing.

• In industrial WWTP we offer total solutions for mainly food and beverage processing industries and other wastewater with organic pollutions. With our aerobic and anaerobic processes cost-effective water treatment is possible with recovery of energy, nutrients and water.

• In manure treatment we offer total treatment of manure, with biogas production, nitrogen recovery and treatment to dischargeable water.
