Processed water from a wastewater treatment plant

Several million house owners will have to retrofit their wastewater treatment systems at a cost of thousands of Euros or replace their existing systems in order to meet the technical standards of the new European Water Framework Directive. The future EU Directive stipulates that all wastewater treatment plants must be retrofitted with a secondary biological treatment to almost completely remove bacteria and nitrogen from the sewage water. There is a good chance to use the AQUALOOP water treatment system as part of this retrofitting.

To upgrade existing wastewater treatment systems the AQUALOOP membrane station can be directly installed within the existing discharge chamber. The collective storage of the processed water is not required anymore. Since water is released in this chamber without coarse dirt and organic contamination, the inflow tank does not require AQUALOOP PURAIN pre-filter and the growth bodies for biological treatment, which saves cost. The treated water will be transferred to a clean water tank and from there it is supplied to the consumers via a RAINMASTER pump and control unit to be reused. The resulting cyclical process saves a considerable amount of water and of course cost. On top of the costs saved, through a reduction in the use of municipal water, the cost for extracting water is also saved at wastewater systems without outlet.
