If individual properties, settlements, municipalities, water cooperatives or associations produce municipal waste water with a daily pollutant load of the untreated water of more than 50 PE60 (PE60 = pollutant load of the untreated waste water of 60 g BOD5 per inhabitant value and day), then the emission limits specified in plant size A apply.

Waste water treatment plants must therefore reduce the following parameters:

+ BOD5 (BOD5 = Biochemical Oxygen Demand in five days) by at least 95%.

+ COD (COD = chemical oxygen demand) by at least 85

+ TOC (TOC = total organic carbon) by at least 85

+ total bound nitrogen (ges. geb. N = sum of organically bound nitrogen, ammonium nitrogen, nitrite nitrogen and nitrate nitrogen) by at least 70%.

Only after these requirements have been met can the treated wastewater be fed into our local watercourses. After the treatment process, sludge remains and this is where we, at Green Sentinel, come in. Our RSR process is the next step in the chain and intervenes from the point where the sludge has been dewatered. By means of the developed treatment process, phosphorus, nitrogen, potassium and other valuable resources can be recovered and made available for other uses, e.g. as fertiliser. The refined sludge corresponds to high-quality compost, as the analysed values are far below the specified limits of quality compost. Through further drying processes, a thermally usable substitute fuel, PecuPower, can be produced.

Environmental protection, climate targets and recycling are not only current topics, but will also accompany us in the future - after all, we want to pass on Mother Earth in good health to our children and grandchildren.  It is important to take the right steps now and we are happy to be able to do our part. With our developed RSR process, we help municipal sewage plant operators to extract the optimum from the resulting sewage sludge and make it usable.
