Abstract :The comparison of parametric statistics for effective removal of turbid-metric particles insert ignore into journalissuearticles values(TDSP); with extracted natural coagulant “chito-protein” insert ignore into journalissuearticles values(CP); and aluminum sulphate has been successfully studied using PWW through coagulation process. PWW contains 2669mg/l relative to the national environmental regulation standard of 100mg/l for dischargeable effluents. CP was extracted from snail shell flour insert ignore into journalissuearticles values(SSF); using the modified Fernandez-kin method. The extracted CP contains mainly protein insert ignore into journalissuearticles values(86%);. From the FTIR analysis traces of lysine, valine, serine and Phenylalanine were observed from the major functional groups insert ignore into journalissuearticles values(NH3+ bending, NH3+ rocking, CH3 asymmetric, OH bending and benzene ring vibration observed at 1456 cm-1,1154cm-1,1336 csm-1,781 cm-1,713 cm-1 respectively); present in CP. The unit cell dimension ao for CP were estimated as 21.3 through the sample’s XRD spectra. The maximum TSDP insert ignore into journalissuearticles values(Total suspended and dissolved particles); removal efficiency of 91.3% was obtained at 4g/l, pH of 4, and 45°C at 25mins for CP -PWW while 90.2% was obtained at 2g/l, pH of 6, 35°C and at 20mins for Alum-PWW system. Floc strength of 1.03 was obtained using alum while a floc strength of 1.322 was obtained using CP. Collision efficiency insert ignore into journalissuearticles values(ɛp); of 5.03E+13 and menkonu constant insert ignore into journalissuearticles values(km); of 6.00E-5 were obtained for CP-PWW coagulation. CP can be an effective alternative to alum in treatment of PWW.
