Wastewater treatment. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it.
Kurita Water Industries Ltd. (栗田工業株式会社, Kurita Kōgyō Kabushiki-gaisha) is a Japanese manufacturer, providing water treatment chemicals and facilities as well as process treatment chemicals. [3] During the 1950s Kurita Water Industries expanded the portfolio and started with the water treatment facilities business, chemical ...
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. [ 2]
As part of the continuing global rollout of LanzaTech’s technology to capture carbon dioxide emissions and turn those emissions into fuel and chemicals, the company is rolling out a new small ...
Some techniques require pre-treatment of wastewater to ensure reliable performance, which could be potentially costly and technically demanding. For instance, presence of bicarbonate ions (HCO 3 − ) can appreciably reduce the concentration of ·OH due to scavenging processes that yield H 2 O and a much less reactive species, ·CO 3 − . [ 4 ]
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. Water treatment removes contaminants and undesirable ...
Water pollution refers to the contamination of water bodies (such as rivers, lakes, oceans, groundwater) by harmful substances or pathogens, making them unfit for human use or harmful to aquatic life. This contamination can occur from various sources, including industrial discharge, agricultural runoff, untreated sewage, and improper disposal ...
Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1]: 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
