Surface aerators and submersible aeration equipment for wastewater treatment
The activated sludge process requires certain types of microorganisms to break down organic matter in wastewater. As any other living organism, the microorganisms need energy to reproduce. When breaking down organic matter or oxidizing ammonium (NH4+) to Nitrite (NO2-) energy in the form of ATP for microorganism reproduction is released. However, both conversions need oxygen. […]
Activated sludge process – Upgrade with IFAS
After explaining how the activated sludge process works in part 1 we are now taking a closer look on how to increase the wastewater treatment capacity of ASP with IFAS systems. IFAS stands for integrated fixed film activated sludge and describes the combination of fill media attached growth systems with the activated sludge process. The […]
