Sedimentation is a primary treatment process that involves the settling of suspended solids in wastewater, allowing them to be removed.

A clarifier is a tank that allows suspended solids to settle and separate from the wastewater, enabling their removal.

Aerobic bacteria are used in the activated sludge process to break down organic matter in wastewater in the presence of oxygen.

A trickling filter is a biological treatment process that involves passing wastewater over a bed of rocks or plastic media, providing a surface for microbial growth and the breakdown of organic matter.

Chlorination is a widely used disinfection method in wastewater treatment, involving the addition of chlorine to kill pathogenic microorganisms.

Tertiary wastewater treatment aims to further polish and refine treated wastewater to meet specific discharge standards or reuse requirements.

Reverse osmosis is an advanced water treatment technology that uses a semipermeable membrane to remove dissolved solids, producing high-quality water.

Constructed wetlands are designed to mimic natural wetlands and provide a natural habitat for wildlife while treating wastewater through natural processes.

Pollution prevention aims to reduce the generation of pollutants at the source, minimizing the need for extensive treatment.

Green infrastructure involves the use of natural or engineered systems to manage stormwater runoff and reduce pollution.

Nanofiltration is an emerging technology that employs nanomaterials to remove contaminants and produce high-quality water.

Water reuse involves the utilization of treated wastewater for beneficial purposes, such as irrigation, industrial processes, or groundwater recharge.

Natural treatment systems, including constructed wetlands, utilize natural processes to treat wastewater and reduce pollution.

Bioremediation involves the use of microorganisms to break down and remove pollutants from water and soil.

A rotating biological contactor (RBC) is a biological treatment technology that uses rotating discs to provide a surface for microbial growth and the breakdown of organic matter.
