With their activities, many industrial plants and facilities consume or produce wastewater. Depending on local laws and permission requirements, the effluent may be released or reused during their process.
The majority of the time, water must be treated to some extent in order to meet quality standards or legal requirements. This process is known as wastewater treatment.
What is pretreatment of industrial wastewater?
Pretreatment is the process by which commercial and industrial facilities treat wastewater, to eliminate dangerous components before discharging it into a sewer system, under the supervision of a publicly owned wastewater treatment plant.
You risk paying fines and facing legal repercussions if you don't properly manage your effluent, or treat your water. Wastewater pretreatment is probably crucial to the quality of your products, aside from avoiding legal penalties.
Pretreatment for industrial wastewater treatment plants
· Chlorine dosing system
To maintain a residual level of free chlorine in feedwater between 0.2 and 0.5 PPM, sodium hypochlorite solution is used to chlorinate it. It includes a solution tank, a pump, and extras. The raw water tank houses the chlorination water.
When microbiological contamination is present, we occasionally advise using ozonation, or chlorine dioxide dosage in raw water.
· System for dosing alum/polymer
The raw water tank is dosed with alum and polymer for the flocculation and coagulation process, which increases the effectiveness of filtration in downstream filters.
· Multilevel filter
After being chlorinated, the water is sent through a Multi Grade Filter (MGF) to remove pollutants. The Multi grade filter is made up of different layers of gravel, coarse sand, and fine sand. It purges the raw water of the suspended particles.
· Multi Grade Filter for the removal of Suspended Solids (SS)
The Multi grade filter is made up of different layers of gravel, coarse sand, and fine sand.Filter supply is available in fully automatic and manual modes.MOC is available for SS, MSRL, MSEP, MS, and FRP with frontal linking pipes, Auto-Manual Multiport valve, and first charge of media. We also advise using Lamella Clarifiers, plate-type clarifiers, when the suspended solid is greater than 50 PPM.
· Activated carbon filter
The removal of organic compounds or the adsorption of free chlorine from water, is done using an Activated Carbon Filter (ACF), which is the next step after filtering the water. The activated carbon filter is made up of pebbles and several layers of activated carbon. The raw water's free chlorine is eliminated.
· Water softener plant
By swapping Ca& Mg Ion with Na, it creates soft water by removing hardness.
· Filter for removing iron
After being filtered, water is next sent through an Iron Remover Filter (IRF) to remove inorganic iron. The resins used in the Iron Remover Filter are of a particular quality. With outlet conditions in the region of 0.3 PPM, it can remove dissolved Iron.
Filters that have had the iron removed are also offered in completely automatic or manual mode. Additionally, FRP/MS vessel MOC is available.
How can we assist?
Netsol Water is aware of the particular requirements for industrial wastewater treatment applications. In contrast to municipal sewage treatment, this treatment requires you to concentrate on the precise procedure that generates the waste stream.
Your wastewater surcharge cost from the city will increase based on how much wastewater, you create and release. The bottom line of your company can be impacted by wastewater pretreatment just like plant production, since it can help you reduce expenses and maintain profits.
At Netsol, we not only assist you in choosing the best water and wastewater treatment system for your needs, but also provide routine maintenance. If you have any questions regarding our services, please don't hesitate to contact our design head or send us an email.
