Subsurface Release Dissolved Air Flotation (DAF) is a water treatment process that enhances the removal of fine particles and suspended solids. The process involves the dissolving of air into water under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles that adhere to the […]

Aeration in Wastewater Treatment: Principles, Techniques, and System Design Aeration is a critical process in wastewater treatment that involves introducing air into sewage to enable aerobic biodegradation of pollutants. Microorganisms require oxygen to break down organic matter into harmless by-products, making aeration a vital component of biological treatment systems. By applying appropriate aeration techniques and […]
