Wastewater coagulation and electrocoagulation were investigated as sorption processes involving colloidal sorbents such as (Al(OH)3)n, (Fe(OH)3)m and (Fe(OH)2)p. An attempt was made to fit experimental data to two popular sorption models. Based on a statistical and mathematical analysis of the obtained results, the Langmuir model of chemical adsorption was regarded more probable than the Freundlich model. The highest maximum adsorption of phosphorus in the analyzed wastewater was achieved with the use of PIX, and the lowest adsorption maxima were reported for an iron electrocoagulant. PAC was most effective in reducing COD of wastewater. PAC and PIX delivered higher adsorption maxima for compounds responsible for COD than aluminum and iron electrocoagulants.
