Film fill plastic media and attached biofilm growth I Wastewater treatment
Biological processes in wastewater treatment can be classified into two main categories: suspended growth and attached growth/ biofilm processes. In suspended growth processes the microorganisms responsible for wastewater treatment are maintained in liquid suspension by appropriate mixing and aeration. The most common suspended growth process is activated sludge. Instead in the attached growth process, the […]
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 […]
