You would know that almost all industries would be working with chemicals and some toxic gases. Whatever may be their processes, they will produce a hell of wastes in the end. However, they will easily spit these wastes in the liquid form outside their premises. Most of this wastewater gets dumped into rivers or other water resources. As water pollution is being the deadliesta deadly factor that causes a range of diseases, industrial wastewater should get treated well before it joins the water bodies. There are several water treatment plants out there to help in this. In this article, let us go through the various steps in industrial water treatment in brief.
Screening – Water directly coming from the industry will contain huge waste particles like paper, wood, plastics, and many more. The screening equipment will take all these unwanted bulk particles out and will send the remaining water out.
Grit removal – In this stage, minute but heavy impurities like sand will get removed as they could form sludge. The removed sand and other particles will get dumped along with the bulk particles in landfills.
Primary setting – Although there are no heavy particles, you can still see some particles ready to get sedimented. This process will allow them to get sedimented and will remove the remaining water from the tank. This stage includes the removal of phosphorous from the mixture using chemicals.
Aeration – As the name suggests, this process adds air to increase the dissolved oxygen in the water, will convert the impurities into cell tissues and water molecules. The process isproviding optimal conditionsactivated by the inclusion of thefor thecertain type of bacteria to quickly break down organic matter that causes damage to rivers and lakes. that will help in the degradation of the impurities as they would do in rivers and oceans.The aeration intensifies the natural reaction that happens in natural water treatment technology water bodies.
Filtration and disinfection – In this stage, the final treated water will get filtered and the remaining bacteria will also get destroyed with the aprocess of such as UVultrasonic disinfection.
