enter in Hypo contact tank then Multi Grade Filter (MGF) feed tank. Treated effluent will then be pumped to an entire treated effluent recycles to board manufacturing process. The sludge generated from primary treatment and biological system taken sludge produced in the process is taken to the belt press dewater well be routed back to the treatment system. The high costs associated with the plant and their operations require a wise optimization of the process. In recent years various systematic design approaches to wastewater reuse across complex manufacturing operations have been developed [7-11]. Because economic benefits are undoubtedly a major driver for industry to implement wastewater reuse programs, recent research in this area has focused on the economic optimization of wastewater reuse systems [12-15]. In the present research is to treat the paper board industry wastewater in biological oxidation in the meaning of environmental
friendly manner and also to know the influences of Temperature, pH, F/M ratio and DO concentration on the microorganism’s growth and pollutant removal and to assess the biodegradability of the wastewater and also to recycle and reuse the waste for economic profits and suitability of a zero discharge system to paper board industry. Materials and Methods Samples collection and analytical methods Wastewater from different streams was collected together as received finally by the ETP through a single drain. For the present study, effluent samples were collected from over flow of sedicell, primary clarifier, aeration tank-A, secondary clarifier -A, aeration tank –B, secondary clarifier –B, Tertiary clarifier and MGF. The liquid waste parameters such as pH, Temperature, TDS, TSS, COD, BOD, Cl and SO 4 were monitored at influent and treated effluent. All the samples
