However, even in the U. Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various methods of water treatment to provide safe drinking water for their communities.
Shop What is Wastewater Treatment? Wastewater treatment is the process of converting wastewater — water that is no longer needed or is no longer suitable for use — into bilge water that can be discharged back into the environment.
Wastewater is full of contaminants including bacteria, chemicals and other toxins. Its treatment aims at reducing the contaminants to acceptable levels to make the water safe for discharge back into the environment.
There are two wastewater treatment plants namely chemical or physical treatment plant, and biological wastewater treatment plant. Biological waste treatment plants use biological matter and bacteria to break down waste matter. Physical waste treatment plants use chemical reactions as well as physical processes to treat wastewater.
Biological treatment systems are ideal for treating wastewater from households and business premises. Physical wastewater treatment plants are mostly used to treat wastewater from industries, factories and manufacturing firms. This is because most of the wastewater from these industries contains chemicals and other toxins that can largely harm the environment.
The latter is called water reclamation and implies avoidance of disposal by use of treated wastewater effluent for various purposes. Wastewater Collection This is the first step in waste water treatment process.
Collection systems are put in place by municipal administration, home owners as well as business owners to ensure that all the wastewater is collected and directed to a central point. This water is then directed to a treatment plant using underground drainage systems or by exhauster tracks owned and operated by business people.
The transportation of wastewater should however be done under hygienic conditions. The pipes or tracks should be leak proof and the people offering the exhausting services should wear protective clothing.
Odor Control At the treatment plant, odor control is very important. Wastewater contains a lot of dirty substances that cause a foul smell over time. To ensure that the surrounding areas are free of the foul smell, odor treatment processes are initiated at the treatment plant.
All odor sources are contained and treated using chemicals to neutralize the foul smell producing elements. Screening This is the next step in wastewater treatment process.
Screening involves the removal of large objects for example nappies, cotton buds, plastics, diapers, rags, sanitary items, nappies, face wipes, broken bottles or bottle tops that in one way or another may damage the equipment.
Failure to observe this step, results in constant machine and equipment problems. Specially designed equipment is used to get rid of grit that is usually washed down into the sewer lines by rainwater.
The solid wastes removed from the wastewater are then transported and disposed off in landfills. Primary Treatment This process involves the separation of macrobiotic solid matter from the wastewater.
Primary treatment is done by pouring the wastewater into big tanks for the solid matter to settle at the surface of the tanks. The sludge, the solid waste that settles at the surface of the tanks, is removed by large scrappers and is pushed to the center of the cylindrical tanks and later pumped out of the tanks for further treatment.
The remaining water is then pumped for secondary treatment. Secondary Treatment Also known as the activated sludge process, the secondary treatment stage involves adding seed sludge to the wastewater to ensure that is broken down further.
Air is first pumped into huge aeration tanks which mix the wastewater with the seed sludge which is basically small amount of sludge, which fuels the growth of bacteria that uses oxygen and the growth of other small microorganisms that consume the remaining organic matter.
This process leads to the production of large particles that settle down at the bottom of the huge tanks.
The wastewater passes through the large tanks for a period of hours. Bio-solids handling The solid matter that settle out after the primary and secondary treatment stages are directed to digesters. The digesters are heated at room temperature. The solid wastes are then treated for a month where they undergo anaerobic digestion.
During this process, methane gases are produced and there is a formation of nutrient rich bio-solids which are recycled and dewatered into local firms.
The methane gas formed is usually used as a source of energy at the treatment plants. It can be used to produce electricity in engines or to simply drive plant equipment.
This gas can also be used in boilers to generate heat for digesters. Tertiary treatment This stage is similar to the one used by drinking water treatment plants which clean raw water for drinking purposes.
The tertiary treatment stage has the ability to remove up to 99 percent of the impurities from the wastewater.Process Water Treatment.
Process water is water that is used for a variety of manufacturing processes, including: boiler make-up water; cooling tower make-up water; coating and plating; rinsing and spraying; washing and many others. Municipal or ground water supplies often contain dissolved minerals which can cause a multitude of problems than can affect product quality and manufacturing Location: Highway 75, Blountville, TN.
Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release to the environment.
Filtration: The water is then filtered through layers of fine, granulated materials — either sand, or sand and coal, depending on the treatment plant.
As smaller, suspended particles are removed, turbidity diminishes and clear water emerges.

What is HiPOx – Advanced Oxidation Process for Water Treatment HiPOx is a patented, continuous, in-line, plug-flow, advanced oxidation process for water treatment (AOP) with innovative injection and mixing techniques that utilizes hydrogen peroxide and ozone to efficiently create hydroxyl radicals (OH•) that destroy organic compounds while.
Water is an essential part of industrial processes. The waning amount of available fresh water, tighter government regulations, cost of water disposal and growing concern for the environment means industry must find ways to treat and reuse wastewater.
That’s where Clearflow comes in.
