Industrial Water Treatment: Six Ways They Treat And Recycle Your Wastewater

Water is a precious resource that we must do our best to preserve and protect. Industrial water treatment companies help make this possible by treating wastewater and recycling it for industrial use. They also provide cleaning services, which can be very helpful in an emergency like a flood or sewage spill! Here are six ways these companies treat and recycle your wastewater:

Wastewater Pretreatment

This process involves removing any solids in wastewater before it is sent over to chemical precipitation or membrane filtration treatment plants. Some industrial water treatment companies will use sedimentation tanks, which allow solid particles like sand and grit to settle on the bottom of these large tanks due to gravity while allowing clear liquid (water) above them to be filtered through different filters where they can remove oil, grease, bacteria, etc. This allows industrial water treatment companies to recycle this clean water for industrial purposes without having dirty contaminants enter into their machines where they cannot get rid of them quickly.


This is one of the first steps industrial water treatment facilities take to filter out oil, grease, sediment, bacteria, viruses, chemicals, and other impurities from the wastewater before sending it on to another phase of treatment. They follow the EPA’s industrial pretreatment standards to ensure that the wastewater they send out meets specific criteria.

Chemical Precipitation

This process involves adding reagents like lime to the wastewater, which causes dissolved metals in it (like lead) to form particles that can be removed. The industrial water treatment company will then collect these particles for disposal or recycling. This process is beneficial because it prevents metals from contaminating other industrial processes.

Coagulation & Flocculation

This process involves mixing solid impurities with coagulant chemicals to become larger and heavier, allowing them to settle out of the wastewater more easily. This method is most often used when removing heavy metals from industrial wastewater.

Membrane Processing

Biological Oxidation. Once this is complete, the clean effluent can be discharged into rivers or waterways according to local regulations. The solids generated during these treatments usually get sent off for final disposal in landfills or waste incinerators, where they will remain safely contained forever!

Chemical Additives

Industrial water treatment facilities also use industrial chemicals to treat the wastewater. They usually attach or inject sodium hypochlorite (NaOCl) into the pipelines, which provide disinfectant properties that kill bacteria in the wastewater as it flows across industrial sites. The NaOCl is then removed at downstream locations by other industrial water treatment companies and its attached impurities!

Industrial water treatment companies make industrial wastewater safe for industrial workers and the environment.
