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.  Looking for a Water Treatment Plants Manufacturer, Operator, and Maintenance Firm?

STPs are crucial to human society and the environment’s well-being in their entirety. As the name suggests, these plants treat sewage water and cleanse it before it is released into water streams, rivers, etc., or reused in any form. But what exactly does an STP do, and how do the concerned authorities ensure its efficiency? Let’s delve into a few aspects of STP operation and maintenance. What is an Sewage Treatment Plants? Sewage Treatment Plant treats wastewater/sewage, breaking it down into a cleaner effluent that can be safely reused or released. STPs are crucial because they help maintain groundwater balance, prevent the spread of diseases, and curtail environmental degradation. In the residential context, STP-treated water can be used for washing cars, gardening, construction, etc. It helps reuse water and avoids water scarcity. How Does an Sewage Treatment Plants Operate? STP works in four phases. Let’s overview each. Preliminary treatment involves removing tree branches, figs, plastic wrappers, bottles, and various other solid materials. Primary treatment takes place in a sedimentation tank that lets organic and inorganic solids settle at the bottom. At the same time, lighter materials, oil, grease, etc., float to the top with the help of skimmers. This is a crucial phase as it helps remove about 55-60 percent of solids. The remaining water moves to the next step.  Secondary treatment involves secondary clarifiers separating biological floc from the liquid via aerobic biological processes. It is done through indigenous microorganisms that consume biodegradable soluble contaminants. The stage helps clean about 90 percent of the water as solids and other pollutants are cleared during the primary treatment. This is the stage where nitrogen, pathogens, and other inorganic compounds are removed. It involves the chemical disinfection of water via UV light or micro-filtration before it is released for reuse. The sludge is then treated in digesting tanks with the help of anaerobic bacteria. The former can be used as a fertilizer. What is Included in Sewage Treatment Plants Maintenance? Maintenance is essential to maintain the STP’s efficiency. While low-quality STPs need frequent maintenance, high-quality STPs also aren’t devoid of maintenance, although not as frequent. However, the latter also requires de-sludged and servicing at least once a year. After the desludging process, the plant should be refilled with water so that internal and external pressure is balanced. STP operators and maintenance professionals must prevent the entry of water, as it could wash out all the bacteria and result in flooding. STP maintenance includes checking the following.
