The coagulation/flocculation is a major process in the wastewater treatment. A study was conducted to compare the efficiency of two polymeric PAC coagulants (PAC, PAX 61) and two monomeric coagulants, Al2(SO4)3 andAlCl3,in pulp and paper wastewater treatment. PAC and PAX 61 showed the advantage over the traditionally used Al2(SO4)3 and AlCl3 in the removal of basic wastewater pollutants. The use of the optimum dose of 10.3 mg Al/dm3 with PAC ensured over 90% removal of turbidity, color and around 50% COD reduction. A similar effect was obtained after the use of an around 50% higher PAX 61 dose

Koagulacja/flokulacja jest głównym procesem w oczyszczaniu ścieków. Przeprowadzono badania porównania skuteczności działania dwóch polimerycznych koagulantów typu PAC (PAC, PAX 61) oraz dwóch koagulantów monomerycznych – Al2(SO4)3 i AlCl3 –w procesie oczyszczania ścieków celulozowo-papierniczych. PAC i PAX 61 wykazywały przewagę nad tradycyjnie stosowanymi Al2(SO4)3 i AlCl3 w usuwaniu podstawowych zanieczyszczeń ścieków. Zastosowanie optymalnej dawki 10,3 mg Al dm-3 z PAC zapewniało ponad 90-procentowe usunięcie mętności, barwy i ok. 50% obniżenie ChZT. Podobny efekt uzyskano po zastosowaniu ok. 50-procentowej wyższej dawki PAX 61.
