KORESPONDENSI: Novel Copolymer Cationic from Agroindustrial Waste using Microwave

Background. A cationic copolymer has been developed as a substitute for synthetic coagulants, resulting in decreased pH, potential health problems, high costs, and large sludge volumes.

Aim. This study evaluated the potential of banana pith in several treatments as a natural coagulant to reduce turbidity, COD, and color.

Methods. The synthesis was carried out by inserting the cationic moiety of GTA (3-Chloro-2-hydroxypropyl trimethyl ammonium chloride) into the starch backbone by microwave radiation.

Resulth. It has been found that the floculation characteristics depend on the charge neutralization, followed by the linkage between the copolymer chains. The results showed that the initial dose and concentration influenced the copolymer's flocculation performance.

Conclusions. Natural polysaccharides can be modified becomes an effective flocculation material for treating clean water and wastewater
