TO THE STUDY OF THE FLOCCULATION AND COAGULATION PROCESS IN THE PURIFICATION OF WATER FOR INDUSTRIAL APPLICATION

It is an important criterion the choice of lighting technique for industrial applications in water purification. In article it was examined research methods coagulation and flocculation process. Today, improvement these techniques use flocculants coagulants, which speed up process flocculation, are relevant. were considered as coagulants sulfuric acid salts Al2(SO4)3 FeSO4. noted advantage over aluminum since iron can be used to purify with different salt composition pH values, work better at low temperatures, characterized by greater strength grain size. application influence cationic flocculant “PuroFloc 890” or anionic “Flopam”, allow clarification without a coagulant. determined coagulant formation. Methods processes intensification separation have been studied, including due thickening particles aggregate under action (coagulants), liquid solid phases. found that resulting suspended layer works like filter, removing fine from water. As accumulate, their concentration increases phenomenon compressed deposition occurs, rate decreases because energy spent on friction. necessary reduce upward flow productivity illuminator,
