COD stands for Chemical Oxygen Demand. It’s a key measure of water pollution in wastewater. COD shows how much oxygen is needed to break down organic matter in water. COD treatment is crucial for protecting the environment and meeting water quality standards. Treating COD in wastewater involves various methods. These can include physical, chemical, and […]

Aeration is a critical process in the treatment of wastewater, involving the introduction of air into sewage to allow aerobic bio-degradation of the pollutant components. It is a vital part of most biological wastewater treatment systems; microorganisms in the wastewater need oxygen to break down organic matter into harmless by-products. Oxygen is supplied through aeration, […]
