Pulsed-power water treatment is the process of using pulsed, electro-magnetic fields into cooling water to control scaling, biological growth, and corrosion. The process does not require the use of chemicals and helps eliminate environmental and health issues associated with the use and life-cycle management of chemicals used to treat water. [ 1 ]
Treatment disposal of human excreta can be categorized into three types: fertilizer use, discharge and biogas use. Discharge is the disposal of human excreta to soil, septic tank or water body. [75] In China, with the impact of the long tradition, human excreta is often used as fertilizer for crops. [76]
Using biochar may decrease N 2 O emissions from soils by an average of 54%. [5] the usage of artificial fertilizer in the agricultural field it leads to nutrition imbalance in the soil. Soils can sequester carbon dioxide (CO 2) from the atmosphere, primarily by storing carbon as soil organic carbon (SOC) through the process of photosynthesis.
Biosolids are solid organic matter recovered from a sewage treatment process and used as fertilizer. [1] In the past, it was common for farmers to use animal manure to improve their soil fertility. In the 1920s, the farming community began also to use sewage sludge from local wastewater treatment plants. Scientific research over many years has ...

to mitigate the adverse effects of shallow water tables and soil salinization, some form of watertable control, soil salinity control, drainage and drainage system is needed; as drainage water moves through the soil profile, it may dissolve nutrients (either fertilizer-based or naturally occurring) such as nitrates, leading to a buildup of ...
Organic fertilization techniques have lower environmental consequences in comparison to the production of artificial chemical fertilizers, because they use no harsh caustic or organic solvents to produce fertilizer and the seaweed raw material is a renewable resource, as opposed to mineral deposits and fossil fuels needed to synthesize chemical ...
Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking , industrial water supply, irrigation , river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
