Water removal is the primary means of weight and volume reduction, while pathogen destruction is frequently accomplished through heating during thermophilic digestion, composting, or incineration. The choice of a sludge treatment method depends on the volume of sludge generated, and comparison of treatment costs required for available disposal ...

Bioremediation is not specific to metals. In 2010 there was a massive oil spill in the Gulf of Mexico. Populations of bacteria and archaea were used to rejuvenate the coast after the oil spill. These microorganisms over time have developed metabolic networks that can utilize hydrocarbons such as oil and petroleum as a source of carbon and ...
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

Activated sludge tank at Beckton sewage treatment plant, UK.The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.
October 9 – Vapors from a leaking pipeline on an oil storage tank exploded and burned in Bridgeport, Illinois. Four oil company workers were killed, and three others injured. [96] October 21 – Two workers bleeding a gas pipeline, in Santa Clarita, California, were injured when gas vapors were ignited, and, one of them later died from the ...
The secondary treatment process also generates a sludge largely composed of bacteria and protozoa with entrained fine solids, and this is removed by settlement in secondary settlement tanks. Both sludge streams are typically combined and are processed by anaerobic or aerobic treatment process at either elevated or ambient temperatures.
Almost all of the natural gas was removed from the field by 1910, but only about 10% of the oil had been removed at that point. The lack of pressure caused by the removal of the gas led to a complete stoppage of oil production, even though an estimated 900 million barrels (140,000,000 m 3 ) of oil remained in the field. [ 3 ]
