Paper Manufacturing

The pulp and paper industry has a great impact in the world. It has been manufactured for ages and ages, it is still booming up as industry in small scale and large scale levels. Despite the fact that they produce printing and writing papers, paper rolls, packaging material etc. they also produce large amount of waste materials from their Industry by Manufacturing. This when left untreated leads to environmental pollution, harsh contamination and so on. As every industry has its own waste water treatment methods to recycle, reuse and reduce pollution. This Industry also has its own criteria to carry out the process of waste water treatment, yet it lags in being efficient in it. By the sources collected and compared with other kinds of industries it is listed that pulp and paper manufacturing industry is one of the top most industries to produce large volumes of waste water which has degradable organics at higher level. Hence this paper aims to study the manufacturing process, waste water components released and its effect on environment, the treatment methods carried out and how it can be improvised efficiently in forthcoming days

A novel agitating system has been developed which allows for individual or combined operation of stirring and aeration processes. Basic fluid mechanical considerations led to the innovative hyperboloid design of the stirrer body, which ensures high efficiencies in the stirring and the aeration mode, gentle circulation with low shear forces, excellent controllability, and a wide range of applications. This paper presents the basic considerations which led to the operating principle, the technical realization of the system and experimental results in a large-scale plant. The characteristics of the system and the differences to other stirring and aeration systems are illustrated. Details of the technical realization are shown, which conform to the specific demands of applications in the biological treatment of waste water. Special regard is given to applications in the upgrading of small compact waste water treatment plants.

Biological Nitrogen

This is a report on the design and operating results of two waste water treatment plants which make use of biological nitrogen and phosphate elimination. Both plants are characterized by load situations that are unfavourable for biological P elimination. The influent of the HILDESHEIM WASTE WATER TREATMENT PLANT contains nitrates and little BOD5. Use of the ISAH process ensures the optimum exploitation of the easily degradable substrate for the redissolution of phosphates. Over 70 % phosphate elimination and effluent concentrations of 1.3 mg PO4-P/I have been achieved. Due to severe seasonal fluctuations in loading the activated sludge plant of the HUSUM WASTE WATER TREATMENT PLANT has to be operated in the stabilization range (F/M ≤ 0.05 kg/(kg·d)) in order not to infringe the required effluent values of 3.9 mg NH4-N/l (2-h-average). The production of surplus sludge is at times too small to allow biological phosphate elimination to be effected in the main stream process. The CISAH (Combined ISAH) process is a combination of the fullstream with the side stream process. It is used in order to achieve the optimum exploitation of biological phosphate elimination by the precipitation of a stripped side stream with a high phosphate content when necessary.

Diffuse pollution, caused by direct discharges from individual houses or groups of houses for which connection to central waste water treatment systems is not feasible, may be significantly reduced by on-site treatment. The performances of 14 different systems for on-site treatment in the range of 5-200 population equivalents (p.e.) in the Netherlands were tested over a two-year period of field research. Treatment results showed reasonably comparable removal percentages in relation to large systems, the effluent quality however may not be as good due to higher influent concentrations. Significant differences in treatment, operation and maintenance aspects were recorded, causing some systems to be preferred to others. A further evaluation involving costs is currently being carried out. The feasibility of wide-spread application of small treatment plants may depend more on financial, management and organizational aspects than on technological aspects.
