Water purification is the primary purpose of water treatment plants. But you don’t receive contaminated water from a single source. Hence, water received from every source comes with a unique treatment requirement. Accordingly, we will look at the various types of water treatment plants and their applications.
Wastewater Treatment Plant (WWTP)
WWTP treats water from agricultural, domestic, industrial, transport, and medical activities. The water is further classified as sewage water and industrial wastewater. While the former is received from bathrooms, sinks, toilets, etc., the latter’s source is industries, manufacturing companies, etc. Applications of WWTP include chemical industries, petroleum refineries, and paper and pulp factories as well.
Effluent Treatment Plant (ETP)
As the name suggests, ETPs treat effluents, which are the byproducts of various industrial activities. ETP applications include industries with high and extensive chemical contamination in wastewater. It includes pharmaceuticals, manufacturing, chemical, and dye manufacturing.
Sewage Treatment Plant (STP)
Sewage treatment plants separate contaminants from the wastewater received from commercial buildings, households, etc. But STPs also handle debris from sewers and rainwater.
STPs are an integral part of human society, as they treat wastewater via various complex procedures, including biological, chemical, and physical processes. Thus, they help avoid the release of contaminated water into the environment.
STPs follow a three-stage wastewater treatment – primary, secondary, and tertiary.
Primary: The wastewater travels into the foremost clarifiers. The natural solid accumulates at the tank’s backside, and lighter particles float at the top.
Secondary: It comprises aerobic aeration, wherein oxygen exchange with the microbes within the sewage enables them to digest the common matter.
Tertiary: The wastewater travels through the sand filters that cast off any final fine particulate matter. Further, the water is subject to UV treatment that eliminates viruses and bacteria that could cause infections.
STP applications include commercial buildings, residential complexes, etc.
Reverse Osmosis (RO) Water Treatment
It refers to a filtration method that removes various contaminants and impurities from the wastewater via pressure when it is on the side of the membrane. Applications include companies that manufacture semiconductors, boiler feed, metal finishing, food, and beverage, etc.
Demineralization (DM) Treatment Plant
Demineralization usually involves the total removal of dissolved solids or minerals from process streams or feedwater. These plants are used in industries that require water with high purity levels, like food and beverage, feed water in high-pressure boilers, electronic manufacturing process streams, etc.
