Wastewater soil absorption systems (WSAS s) have the potential to achieve high treatment efficiencies, yet the understanding and predictability of performance as well as the risk of inadequate function has not been fully quantified. This has been due to the complex and dynamic relationships between hydraulic and purification processes and the factors that control their behaviors. This paper provides an overview of WSAS process principles and performance, and then describes initial experimental research completed as part of a long-term program ....etc

Wastewater Treatment systems rely on microbes to perform the function of the breakdown of sewage influent. These microbes live in the sludge of treatment plants and holding tanks. They digest the solids and breakdown various compounds. Some wastewater treatment systems are exceptionally efficient, others perform effectively soon after start up, but later stop performing as well.
The key to understanding how and why some wastewater treatment systems work well and others don't, is the need to understand what these microbes need to function. As mi ....etc

ABSTRACT
Necessity is the mother of invention. Energy crisis is the cry of
future.
The historical and the present-day civilization are closely interwoven
with energy and in future, our existence will be more dependent upon
energy. The conventional sources of energy, the single most important
pre-requisite for power generation, are depleting fast. The world is
heading towards a global energy crisis mostly due to running out of
these energy sources; decreasing the dependency on fossil fuels is

Need For Low Energy- Intensive Methods For Treating Low Strength - Large Volume Wastewater (like sewage, industrial washwater, etc.)

1.1 Definition of Low Strength Wastewater

Typical composition of untreated domestic wastewater (influent) was defined using concentration levels as weak, medium, and strong. Weak, medium, and strong levels of BOD5 (mg/L) were identified as 110, 220, and 400, concentrations of TSS (mg/L) were identified as 100, 220, and 350, and concentrations of F ....etc

Membrane Bioreactor for Wastewater Treatment

Recent technical innovation and significant membrane cost reduction have pushed membrane bioreactors (MBRs) to become an established process option to treat wastewaters. The combination of membrane separation with a suspended growth bioreactor is now widely used for municipal and industrial waste treatment (Judd, 2006). When used with domestic wastewater, MBR processes could produce effluent of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for u ....etc

modern Wastewater Treatment Methods
& Disposal techniques
Satisfactory disposal of wastewater, whether by surface, subsurface methods or dilution, is dependent on its treatment prior to disposal. Relatively simple wastewater treatment technologies can be designed to provide low cost sanitation and environmental protection while providing additional benefits from the reuse of water.Adequate treatment is necessary to prevent contamination of receiving waters to a degree which might interfere with their best or intended use.
The whole ....etc
