Test type: First laboratory test for selection, then Self-performed full-scale test The test is carried out, at Frejlev wastewater treatment plant. The selected polymer will be used at all four plants. The wastewater treatment plant is a mechanical, chemically, biologically active sludge plant. Only final drainage is carried out at the plant. Surplus sludge from Krumsø Wastewater Treatment Plant (1,400 PE) is added to the inlet into the treatment plant and drained together with the plant's own sludge. 155 kg of polymer must be supplied for own full-scale test. Minimum TS% requirement for final drainage with requirements of 19 -23% TS. Minimum requirements Shrimp water quality must be observed. Here, there must be a maximum of 70-100 ml of precipitate in a 1000 ml measuring cylinder glass.

Faxe Forsyning, Haslev Wastewater Treatment Plant Test type: First laboratory test for selection, then Own performed full-scale test Haslev wastewater treatment plant is a mechanical, chemically, biologically active sludge plant, which was renovated in 2012. No surplus sludge is brought to the treatment plant from other treatment plants. The plant has sludge mineralization plants, which are overloaded. So, the screw press should relieve the beds and be used for winter driving. 125 kg of polymer must be supplied for own full-scale test.
