Synthesis and application of polyacrylamide grafted magnetic cellulose flocculant for wastewater treatment

A continuous presence of organic loads in palm oil mill wastewater treatment plants has lately risen as a major issue. This situation shows that coagulation-flocculation process should be overhauled in removing micro-size particles from palm oil mill effluent. Therefore, a direct flocculation proces...

Important parameters including flocculants dosage, pH of solution and settling time were varied to study the effects of these independent variables.

It was observed that the best condition for the reduction of TSS, turbidity, COD, and colour were achieved at flocculants dosage of 1.5 g/L, pH of 8.0 and settling time of 30 minutes. Under this condition, the reduction of TSS, turbidity, COD, and colour was 82.97%, 88.62%, 53.23% and 91.76%, respectively.

In conclusion, direct flocculation by utilizing PAM-g-mcOPEFB can possibly be one of the best alternative flocculants to remove small particles of organic matters in palm oil mill treatment plants due to its simplicity and environmentally friendly method. 2018 Thesis http://eprints.utm.my/id/eprint/81612/ http://eprints.utm.my/id/eprint/81612/1/MohamedHizamMohamedMFChE2018.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:119442 masters Universiti Teknologi Malaysia Chemical and Energy Engineering
