The efficiency of municipal waster water treatment plants must be constantly checked and adapted to meet the actual legal requirements with the best available technologies. The best available technology includes not less than a mechanical treatment stage and a biological treatment with enhanced nutrient removal. Together with new treatment stages, e.g. to meet especially stringent effluent limits for sensible receiving water bodies or for the so-called “fourth” treatment stage, also the rehabilitation of existing treatement stages under operation conditions poses special challenges to design and construction companies.
OSWALD SCHULZE posseses the long standing experience in the project specific realization of suitable processes and measures to meet these challenges under optimum technical and economic conditions.
For municipal waste water treatment we are particularly specialized in the following process technologies:
