Microbial electrolysis carbon capture (MECC) is a carbon capture technique using microbial electrolysis cells during wastewater treatment. MECC results in net negative carbon emission wastewater treatment by removal of carbon dioxide ( CO 2) during the treatment process in the form of calcite (CaCO 3), and production of profitable H 2 gas.
Aerobic digestion. Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [ 1] for subsequent use. [ 2] More recently, technology has been developed that allows the treatment and reduction of other [ 3] organic waste, such as food, cardboard and horticultural waste.
Additionally, AOPs can be used to treat effluent of secondary treated wastewater which is then called tertiary treatment. [6] The contaminant materials are largely converted into stable inorganic compounds such as water, carbon dioxide and salts, i.e. they undergo mineralization.
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.

Formerly considered the most important PAO in waste treatment, the bacteria is highly abundant in wastewater treatment plants globally. [ 5 ] [ 11 ] It can consume a range of carbon compounds, such as acetate and propionate, under anaerobic conditions and store these compounds as polyhydroxyalkanoates (PHA) which it consumes as a carbon and ...
Pulling just one carat of diamond out of the ground demands workers to move close to 100 square feet of soil, resulting in nearly 6,000 pounds of waste material and up to a ton of released carbon ...
Hydrothermal carbonization ( HTC) (also referred to as "aqueous carbonization at elevated temperature and pressure") is a chemical process for the conversion of organic compounds to structured carbons. It can be used to make a wide variety of nanostructured carbons, simple production of brown coal substitute, synthesis gas, liquid petroleum ...
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 public sewers are not available ...
