Different Types of Chemicals Used in a Wastewater Treatment

Wastewater treatment is important for us from a personal and environmental point of view. Wastewater treatment plants use complex processes that involve the use of different chemicals for treating used water to eliminate pollutants, contaminants, and other organic compounds from water so that they can be introduced back to the environment.

Water treatment plants use several processes including biological and chemical processing that requires the use of different chemicals to disinfect water and balance the pH level. You can also buy water treatment chemicals for sale for wastewater treatment.

Let's discuss the main chemicals used in wastewater treatment plants depending on the application.

pH neutralization of water

To balance the pH level of the wastewater, you can add the basic chemicals to the water that includes alkalis and other acidic acids.

Use of chemical precipitation to remove heavy metals

Chemical precipitation is a process that helps remove heavy metals from wastewater. You can add precipitation reagents to water to remove contaminants. Heavy metals are bounded ionically with reagents formed into solid particles. These solid particles are then removed from water using filtration.

Chemical Coagulants

Chemical coagulants are aluminum or iron-based chemicals that help in removing pathogens, fluoride, organic compounds, and other contaminants. They work to destabilize wastewater particles by introducing positively charged coagulant that reduces the negative charge of the particles. The waste particles form into larger bodies that can be filtered out.
