Recycling of latex wastewater by chemical treatment

Abstract

Glove factories, wastewater contains a large amount of latex which is not biodegradable. Latex wastewater can be treated through: aeration, chlorination, sulfonation, biological treatment, filtration, coagulation, ozon oxidation and using activated carbon. In this paper a new method for treating latex wastewater has been reported. Sulfuric acid has been used for separation of latex from wastewater. This method is compared with limits. The other advantages of this method are recovery of latex for other uses, decreasing coagulation and biological method. BOD and COD of the effluent are lower than DOE limits. The other more advantages of this method are recovery of latex for other uses, decreasing energy consumption and recovery of water.
