How Wastewater Treatment Begins

Wastewater treatment includes a number of processes where pollutants and debris are eliminated from water before discharging it to the environment or recycling it back. Knowledge of the stages of wastewater treatment assists in knowing how waste water plants handle the waste water coming to them.

Primary Treatment: Screening and Grit Removal

The process starts with the screening process where large materials like plastic, rags, and other objects are removed from the waste. This is followed by grit removal whereby sand, gravel, and other small particles that can affect machinery are separated. Primary clarifier then enables the removal of heavy materials and fats/oils.

Biological Treatment: Secondary Treatment

In the biological treatment process, microorganisms feed on the organic components present in wastewater. The supply of oxygen in the aeration process ensures this is possible. In secondary clarification, separation of biological components from the effluent is done; some of the activated sludge is returned to the process.

Filtration and Disinfection

The filtration process helps remove more suspended particulates after previous processes. The use of disinfection, which may include ultraviolet radiation or chemical disinfection, is used for controlling hazardous microorganisms. In some instances, there may be a need for further aeration before release.

Improving Treatment Plant Efficiency

The Lakeside Equipment Corporation highlights the significance of proper equipment and efficient functioning of the plants. Automation, energy-efficient pumps and motors, as well as proper process control, can assist plants in coping with the variable wastewater flows, unnecessary energy consumption, and constant performance of the treatment process.

Each step of the treatment process is well understood. This will allow operators to recognize the requirements for equipment, schedule maintenance, and increase efficiency of the whole process.
