Abstract

Biological treatment using the activated sludge method and biofilm process has been developed for paper wastewater treatment. It is known that a water treatment using biofilm process has a high efficiency be-cause a great deal of microorganism could adhere to media. It is also known that various plastics such as polyurethane and polyethylene have been used as the media. In this study polyethylene was used as a media and rice straw an additive agent to improve porous and hydrophilic properties of the media for waste water treatment. Porosity and hydrophilic characteristics of polyethylene was increased as rice straw was added to polyethylene. Paper wastewater was then treated with newly developed environment materials. Rice straw showed excellent results in waste water treatment in various media. This environmentally friendly material prepared by polyethylene and rice straw could show similar results to those of a commercial porous polyurethane foam in wastewater treatment.
