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 ...
To clean the sponge, they washed it in a bucket with water and salt or vinegar. [12] This became a breeding ground for bacteria, causing the spread of disease in the latrine. [10] It is commonly believed the Romans used sea sponges on a stick and dipped in vinegar after defecation (for anal hygiene), but the practice is only attested to once. [13]
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 ...
Antiseptic. An antiseptic ( Greek: ἀντί, romanized : anti, lit. 'against' [ 1] and σηπτικός, sēptikos, 'putrefactive' [ 2]) is an antimicrobial substance or compound that is applied to living tissue to reduce the possibility of sepsis, infection or putrefaction. Antiseptics are generally distinguished from antibiotics by the ...
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 ...
Avoid throwing fibrous vegetables such as onions, celery, corn husks, fruit peels, and artichokes into your drain. “Items like celery, artichokes, and onion skins can get tangled in the disposal ...
Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. Organic materials in the liquid are catabolized by a microbial ecosystem . A septic drain field, a septic tank, and ...
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 ...
