Biological wastewater treatment
Optimum adjustment of biological processes in wastewater treatment
As part of biological wastewater treatment, bacteria require a well-balanced nutrient system of carbon, nitrogen, phosphorus and special trace elements. Industrial wastewater in particular often exhibits nutrient deficits, which can lead to a drop in performance or even the demise of the biomass. With anaerobic systems, too, biogas production may fail.
Sludge flotation is a serious problem in many activated sludge plants. Floating sludge, or bulking sludge, is caused by an increase in filamentous organisms in the biomass and requires the use of special treatment chemicals. We offer various powder or liquid products that prevent sludge flotation.
We treat the excess sludge produced in biological systems, so that an optimum dewatering result is achieved, and disposal costs are minimised.
A selection of tasks for which we offer solutions:
In the meat industry, for example, wastewater with a high organic load is produced during the cleaning of production plants.Read more
A food manufacturer has reduced water treatment chemical consumption and sludge disposal costs by using different products in its wastewater treatment plant.Read more
A large dairy uses a tailor-made plant solution from EnviroChemie to recycle its liquid waste and efficiently reduce energy consumption and operating costs.Read more
A multi-national dairy co-operative wanted to treat its vapour condensate sustainably at a German site and thus reduce its fresh water requirements and operating costs.Read more
The Norrmejerier dairies generate energy, conserve resources and reduce operating costs using a Biomar® anaerobic wastewater treatment system.Read more
Dairies use water for many different stages in the production process. There are often potential savings to be made here in terms of resources and energy. To achieve this, however, an integral view is required, since the cycles used in dairies, which have often grown over the years, are highly…Read more
