Sewage treatment refers to the process of removing contaminants in domestic or industrial waste water (hereinafter referred to as lower waste water).
It minimizes environmental problems in water circulation or to re-use water that has been treated. The typical method used to treat waste water is biological treatment using microorganisms’ metabolic process. Among this, active sludge is the most common method.
·The process of filtering mud, sand and other particles that has flowed into the sewage water.
·The process of separating sediments and supernatants.
·The process of decomposing organic matter by supplying oxygen to aerobic microorganisms.
·The process of sending the pure water to the discharge site after the organic matter has sinked to the bottom.
·The process of filtering out water one more time in the filtration basin.
·The process of disinfecting one more time using chlorine and UV before being transferred to the discharge site.
Generally, purified water means using surface water (river, lake, etc.), underground water, sea water, stream water and other water resources to purify and supply it according to the user’s purpose, from drinking water to water for industrial use.
The treatment method is mainly composed of a combination of a solid-liquid separation step, filtration and disinfection. In general, when the purified water quality does not meet the management target even after the purification process, advanced water purification processes such as active carbon treatment method, ozone treatment method, bio treatment method and Membrane etc. are combined as a treatment method.
· A process in which water is drawn from the source to the treatment facility.
· A process of injecting chemicals such as polyaluminium chloride, activated carbon and chlorine to remove harmful substances that are present in water.
· A process where sediments are formed by gathering impurities through the injected chemicals.
· A process where the condensed impurities go to the a sedimentation basin and the clear supernatant portion is classified to go to the filter basin.
· A process where impurities are filtered out one more time in the filter basin.
