Abstract

Microbial denitrification effect of wastewater using various polymeric materials was compared and the following results were obtained. Biodegradable polycaprolactone (PCL) was very effective for the denitrif ication, followed by cellulosic materials namely, kenaf, cotton cloth and cellophane. Biodegradable poly (lactic acid) (PLA) provided a little effect, and low density polyethylene (LDPE) and poly (vinyl alcohol) (PVA) scarcely showed dentrification effect. The results were coincided with the weight loss and surface change of the samples.
