Sewage septic tanks

Cess Pools This system is similar to a septic tank, in performance. Sewage water usually seeps through the open bottom and portholes in the sides of the walls. These can also clog up with overuse and the introduction of detergents and other material which slow up the bacterial action. 

Septic Tank Untreated liquid household wastes (sewage) will quickly clog your absorption field if not properly treated. The septic tank is a holding tank in which this treatment can take place. When sewage enters the septic tank, the heavy solids settle to the bottom of the tank the lighter solids, fats and greases partially decompose and rise to the surface and form a layer of scum. The solids that have settled to the bottom are attacked by bacteria and form sludge. 

A septic tank is a purification installation designed to accept the whole sewage/trade discharge from premises. Its construction is such that it allows the settling out... 

Industrial plants also discharge domestic sewage. It is vital to keep this separate from any industrial effluent which may have to be treated, so that it can then be disposed of by conventional means (to the public sewer, septic tank, etc.). 

Cresols are widely distributed natural compounds. As discussed above, they are formed as metabolites of microbial activity and are excreted in the urine of mammals (Fiege and Bayer 1987) and humans (Needham et al. 1984). Cresols from human urine are probably biodegraded at municipal sewage treatment facilities prior to release to ambient waters. However, for combined septic and storm sewage systems, cresols may be released to surface waters during periods of precipitation when influent volumes exceed treatment plant capacities. Also, in rural and suburban areas where septic tanks are used (o- and m-cresols can resist anaerobic digestion), human excrement may be a nonpoint source release of cresols to groundwater. 

Another common source of groundwater pollution is sewage, which includes drainage from septic tanks and inadequate or broken sewer lines. Animal sewage, especially from factory-style animal farms, is also a source of groundwater (and river water) pollution. Sewage water contains bacteria, which if untreated can cause waterborne diseases such as typhoid, cholera, and infectious hepatitis. If the contaminated groundwater travels relatively quickly... 

Many of the world s residential areas have no central sewage systems, and the domestic sewage goes to septic tanks or to toilet pits. The resulting... 

A tonrist camp is to be developed for 400 persons. Estimate the volume of the septic tank to be constructed to handle the sewage produced. 

Most household cleaning products are formulated to be used with water and go down the drain into wastewater treatment systems (municipal sewage treatment plants or septic tank systems). To assure that these types of products are safe for the environment, manufacturers evaluate the impacts of product ingredients in wastewater treatment systems, streams, rivers, lakes, and estuaries. Environmental risk assessment considers the exposure concentrations and effects of individual ingredients. 

Septic tanks differ from sedimentation tanks in the main purpose for which they are built to accomplish. Sedimentation tanks are for sedimentation of solids in suspension. Sometimes coagulants as lime, alum, sulphate of iron, etc., are added as sewage enters the sedimentation basins. On the other hand septic tanks are constructed with the idea of favoring bacterial and enzymatic destruction of the organic matter of sewage. 

The primary sources of bacteria in water are human and animal wastes, seepage or discharge from septic tanks, sewage treatment facilities, and natural soil and plant bacteria. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses. The EPA requires that aU public water suppliers regularly test for coliform bacteria and deliver water that meets the EPA standards. The EPA Maximum Contaminant Level (MCL) for coliform bacteria in drinking water is zero total cohforms per 100 mL of water (56).
