The paper presents the influence of the quality of water subjected to treatment on the filtration process, using self-cleaning DynaSand filters with contact coagulation. Technological factors directly influencing the filtration process and filtrate quality were identified, e.g. variable flows, retention time on filter bed and filtration speed. In addition, the purification process of rinse water in the Lamella separator and its impact on the filtration process were investigated. The Lamella separator combined with the flocculation tank, in which the coagulation, flocculation and sedimentation processes are carried out, is an excellent solution to the problem involving the formation of large amounts of rinse water after washing the sand bed of DynaSand filters. The rinse water of fast filters is cleaned on the Lamella separator and returned to the beginning of the filtration system, before DynaSand filters. This solution allows to minimize water losses in the discussed WTP.
