Aerobic treatment system. An aerobic treatment system ( ATS ), often called an aerobic septic system, is a small scale sewage treatment system similar to a septic tank system, but which uses an aerobic process for digestion rather than just the anaerobic process used in septic systems. These systems are commonly found in rural areas where ...
Groundwater pollution, water pollution e.g. during floods [ 1] A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater ( sewage) flows for basic sewage treatment. [ 2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate ...
Mound system. A mound system is an engineered drain field for treating wastewater in places with limited access to multi-stage wastewater treatment systems. Mound systems are an alternative to the traditional rural septic system drain field. They are used in areas where septic systems are prone to failure from extremely permeable or impermeable ...
Chloroxylenol, also known as para-chloro-meta-xylenol ( PCMX ), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s. First synthesized in Germany in 1923, it was borne out of the ...
To use, mix equal parts white vinegar and water in a spray bottle. Add a few drops of dish soap for additional cleaning power. Simply spray on surfaces and wipe away with a clean cloth or paper ...
The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage. Sanitary sewers serving industrial areas may also ...
