The guaranteed parameter values correspond to the specific requirements of the Czech legislation, while the guarantees for other countries are specified and offered individually and/or upon request. In doing this, it is issued from the values measured in the type test according to EN 12566-3+A2.
Note: In the case of individual equipping of WWTP with dosing of coagulants, it is possible to provide for even further reductions in the outlet concentrations in individual cases, namely the removal of phosphorus
