Abstract
The comparison of parametric statistics for effective removal of turbid-metric particles (TDSP) with extracted natural coagulant “chito-protein” (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 (SSF) using the modified Fernandez-kin method. The extracted CP contains mainly protein (86%). From the FTIR analysis traces of lysine, valine, serine and Phenylalanine were observed from the major functional groups (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 (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 (ɛp) of 5.03E+13 and menkonu constant (km) of 6.00E-5 were obtained for CP-PWW coagulation. CP can be an effective alternative to alum in treatment of PWW.
