UTILIZATION OF GELATIN DERIVATED FROM BOVINE SKIN WASTE AS RENEWABLE FLOCCULANTS FOR WATER TREATMENT APPLICATION

Abstract


The quality of water from groundwater, rivers, lakes, and reservoirs in some places has decreased. In order not to be a problem, then the water needs to be processed before use. The use of flocculantsare preferred compared to the coagulants in water treatment processes, because more stable of the influence of pH and slightly dosage. Polymer flocculants synthesis of non-renewable materials are still widely used, but can cause health and environmental problem. Therefore it takes flocculants polymers derived from renewable natural material, which are safe, affordable cost, suitable for a variety of purposes and has high activity. Some derivatives of polysaccharides and protein can be used as flocculants, some certain protein have equivalent activity to flocculant synthesis polyacrilamide (PAM). Gelatine from bovine skin waste is proreins derived from collagen by hydrolysis, its has ability as a flocculants, procine gelatine even have the ability 2,6 times greater than the anionic PAM. Gelatine as a flocculant may be used singly, modified, or combined with other types of flocculant for purification application, water and waste water treatment.
