Model wastewater whose composition resembled that of pulp and paper wastewater was treated by electrocoagulation under laboratory conditions. The process was carried out in an electrolytic tank with aluminum electrodes. Following electrocoagulation, sedimentation and decantation, COD, turbidity, suspended solids and color were determined in a solution above the sludge layer. The parameters of COD removal efficiency were also calculated. It was found that electrocoagulation is an effective method of wastewater treatment, offering a viable alternative to chemical coagulation. The efficiency of pollutant removal is highly dependent on the initial load of crude sewage.

W warunkach laboratoryjnych ścieki poddawano elektrokoagulacji. Do badań użyto ścieków modelowych, składem zbliżonych do ścieków celulozowo-papierniczych. Proces prowadzono w elektrolizerze z elektrodami glinowymi. Po elektrokoagulacji, sedymentacji i dekantacji w roztworze nad osadem mierzono: ChZT, mętność, zawiesiny i barwę. Obliczono wskaźniki charakteryzujące usuwanie ChZT z elektrokoagulowanych ścieków. Stwierdzono, że elektrokoagulacja jest skuteczną metodą oczyszczania ścieków i pozostaje alternatywą koagulacji chemicznej. Wynik oczyszczania w dużym stopniu zależy od obciążenia ścieków surowych.
