The pulp and paper industry generates the enormous volume of effluents containing a variety of hazardous waste from chemical pulping, bleaching, papermaking, dyeing, cleaning and degreasing processes.    The high BOD and COD effluents from acid, alkaline, chlorine, pigments, waxes, paints and solvents will cause acute toxicity, which impacts on aquatic plants and animals.   Under strict environmental regulations, the organic compounds and toxic substances of effluents have been significantly reduced by the high efficient chemical and biological treatment system as well as the waste minimization techniques by recycling method.   With clearly understanding of the pulp and paper industry and professional experience, we serve the excellent design with basis on system efficiency, cost-saving including concerning on environmental impact.
