A flocculant (DES0-0) was synthesized by epichlorohydrin and diethylamine, followed adding crosslinking agent such as ethylenediamine, diethylenetriamine triethylenetriamine to obtain the crosslinked polymer DES0-1, DES0-2, DES0-3. The flocculation effect of DES0-3 PAM studied measuring volume, transmittance particle size clarified solution after flocculation. results showed that triethylenetet...

about 700000 m3 of waste water is produced from zirab coal washery plant every year. this black water not only carries about 4000 tons fine coals, it also contains waste water pollution. in this investigation by flocculation studies under optimized conditions (like concentration of flocculant, 0.0015 g/t, ph=8, concentration of silicate 0.01 g/t as depressant, and r.p.m. of 150) has been shown ...
