A METHOD FOR WASTEWATER TREATING FROM LIGNIN AND HEMICELLULOSE SUBSTANCES AT WOOD PROCESSING PLANTS
摘要
Invention relates to wastewater purification from lignin and hemicellulose substances. The invention is a method using coagulant composition. The composition contains polyaluminium chloride and aluminium chloride in a ratio 1.5/1 - 1/1. Addition of the coagulant to wastewater should occur at the pH values 6.0 - 7.0. The optimal efficiency of purification occurs in a temperature range from 14 to 40 degrees Celsius.
