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.

Various interactions of sewerage and waste-water treatment are discussed for the typical situation in the Netherlands. Sewerage and waste-water treatment are no longer necessary when each house has its own integrated waste-water system; however, costs seem to be high. The same applies for small-scale waste-water treatment versus centralisation. However, centralized waste-water treatment plants suffer from specific problems due to high fluctuations, not only in hydraulic but also in biological load. With stringent effluent standards the need increases for complete treatment instead of by-passing the peak flows. Besides, the application of buffering tanks may change in favour of an increase in the hydraulic capacity of the waste-water treatment plant. Finally, a new, integrated, attitude on water-cycle problems must be advocated.

A research that analyzed the relationship between biogas production as renewable energy and performance of waste water treatment in tofu small industry using AnSBR reactor has been conducted. This research used system operation method in batches in to get a description of how the biogas production system works as it was operated in the batch mode, which is applied in tofu industry. An instrument capable of operation in batch mode using AnSBR reactor was designed as it does not require sludge re-circulation. An AnSBR reactor includes five stages of; filling, reaction, settling, decanting, and stabilization (idling state). The research was run for 24 days using biogas collected in a tank. Biogas was measured for each HRT starting on the second day HRT to 24th day HRT. Biogas characteristics were monitored on day 16th for contents of CH4, CO2 and heat value. Results show that CH4 content in the biogas amounts to 78.26 %, while CO2 comprises 20.16 %. Meanwhile, the heat value, which depends on acid methane and CO2 content, is 4,246.55 kkal/kg.

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
