Development of finishing materials using adsorption deodorizing function of the dewatered sludge as a raw material

Abstract

The coagulated sediment recovered at the water purification plant is the purified soil generated. Since this generated soil always generates a certain amount in the water purification process, how to use it has been studied, but since most effective use can not be found, most of it is landfilled. As a result of investigating resources, we found that there is adsorption function in the soil generated. As its characteristic, it was found that it has a deodorizing effect by adsorbing ammonia, acetic acid, formaldehyde and the like generated in daily life. So we developed finishing materials and deodorants that utilize the adsorption deodorizing function of the soil generated.
