ABSTRACT
A key factor for the development of any country’s economy is industrialization, but the wastes released are one of the major sources of worldwide environmental pollution. The effluents released from industries such as tannery, textile, food, pulp and paper, distillery, pharmaceutical, oil refinery, etc., is of major concern since these consist of an array of organic and inorganic recalcitrant pollutants and toxic heavy metals. Pulp and Paper industries generate wastewaters formed by various class pollutants of complex mixtures of organic materials such as lignin, extractives, and degradative carbohydrate products, and solids. The wastewaters emerging from Pulp and Paper (P&P) industries are highly variable, especially when comparing one pulp or paper making process to another. The fibers in the wood are separated by the mechanical process for obtaining virgin pulp, which is most often used in the production of high-circulation magazines and newsprint papers. Due to low strength property, sulfite pulps are produced less than kraft pulp.
