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 ...
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 ...
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 ...
Sodium thiosulfate ( sodium thiosulphate) is an inorganic compound with the formula Na2S2O3· (H2O)x. Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water. The compound is a reducing agent and a ligand, and these properties underpin its applications.
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 ...
Staphylococcus aureus. Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus ( MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
