An Understanding of Industrial Wastewater Treatment Procedure

Industrial Wastewater is usually the liquid discharge from manufacturing processes. After water has been used in various industrial processes, it is treated for reuse purpose. The key objective of wastewater treatment is by and large to let human and industrial effluents to be disposed of without creating a risk to human health or deplorable damage to the natural environment. After treating the industrial waste water, it returns to the environment in a way consistent with water quality regulations. Usually, the industrial wastewater treatment covers up the means and methods that are used to treat wastewater produced as a by-product of industrial or commercial activities.


After completing the treatment procedure, the treated or purified wastewater is either reused or released to a sanitary sewer or to surface water in the environment. The biodegradable organic materials of plant or animal origin in the industrial wastewater are quite easy to treat using extended conventional sewage treatment processes, such as

  • Activated sludge process: Activated sludge is a popular biochemical process that is used to treat sewage and industrial wastewater. The process use air and microorganisms to biologically oxidise organic pollutants, resulting in producing a waste sludge containing the oxidised material. Under activated sludge process, air is injected into the aeration tank and is thoroughly mixed into the wastewater. The waste sludge is then allowed to settle in a setting tank, also known as a clarifier or settler. A part of the waste sludge is recycled to the aeration tank and the left over waste sludge is removed for further treatment and final disposal.
  • Trickling filter process: Trickling filters are basically the conventional aerobic biological wastewater treatment units. They are usually comprised of gravel, rocks, plastic, slag and other media over which the flows downward and contacts a layer of microbial slime. The pre-treated wastewater is trickled over the filter using a rotating sprinkler. The process involves assimilation of organic compounds in the wastewater by the microbial slime layer, dispersion of air into the slime layer to supply the oxygen required for the biochemical oxidation of the organic compounds. The end products of trickling filter process include water, carbon dioxide gas, etc.

Industrial wastewater usually comprised of an assortment of impurities; thus, require a treatment composed of special tasks as mentioned above.

There are many water supply companies in the UK that provides water and sewerage supply services. Northumbrian Water is one of the well-known water companies in the UK, offering mains water and sewerage services in various regions of Northumberland. They are amongst the UK’s ten largest water and sewerage companies, providing services to approximately 2 million properties. You can use the Northumbrian Water contact number to discuss about their wastewater management services. You can also call them to inquire about their products, changing account details, understanding water bills, reporting a water leakage, installing water meters, saving water and reducing costs and for general help and support.
