The aim of the studies carried out at full technological scale was to indicate optimal systems of the two-stage precipitation and coagulation (PIX 113 - SAX 18, PAX XL1 - SAX 18, ALCAT 102 - lime milk and SAX 18 - PAX 16) in the process of eliminating heavy metals from wastewaters made in the processing plant producing sub-systems for domestic appliances. Precipitated pollutions were thickened by flocculation and separated by hydrogen peroxide enhanced pressure flotation. The experimental installation of maximal flow capacity: 10.0 m3/d consisted of: the storage-equalization tank, the processing pipe reactor, the pressure flotation station, and the reagent preparation and dosing station. Optimal doses of reagents and a flocculent as well as pressure and saturation time were defined for which maximal reductions in the load of heavy metals were achieved. The usefulness of hydrogen peroxide as a means of enhancing flotation was tested. The use of two-stage precipitation permitted the reduction in heavy metals (Cd, Cu, Cr, Ni, Sn, Zn), eg by applying ALCAT 102 - lime milk at the level exceeding 80%.

Przeprowadzono badania w pełnej skali technologicznej, mające na celu wytypowanie optymalnych układów dwustopniowego strącania i koagulacji (PIX 113 - SAX 18, PAX XL1 - SAX 18, ALCAT 102 - mleko wapienne i SAX 18 - PAX 16) w procesie usuwania metali ciężkich ze ścieków z linii wytwarzania podzespołów do sprzętu gospodarstwa domowego. Wytrącone zanieczyszczenia zagęszczano flokulacyjnie i wydzielano techniką flotacji ciśnieniowej wspomaganej nadtlenkiem wodoru. Instalacja doświadczalna o maksymalnej przepustowości 10,0 m3/d składała się z ziemnego zbiornika magazynująco-uśredniającego, rurowego reaktora procesowego, stacji flotacji ciśnieniowej oraz stacji przygotowania i dozowania reagentów. Wyznaczono optymalne dawki reagentów oraz flokulantu, a także ciśnienia i czasu saturacji, dla których zachodziły maksymalne redukcje ładunku metali ciężkich. Sprawdzono przydatność nadtlenku wodoru w procesie wspomagania flotacji. Zastosowanie dwustopniowego strącania pozwoliło na uzyskanie redukcji metali ciężkich (Cd, Cu, Cr, Ni, Sn, Zn) np. za pomocą układu ALCAT 102 - mleko wapienne na poziomie przekraczającym 80%.
