■ About biofilm process Biofilm process is one of various wastewater treatment method, and it is a method to attach microorganisms onto carrier and to make them decompose contaminants. The microorganisms attached on surface of carrier is called biofilm. Activated sludge process is a process to generate small floating activated sludge and microorganisms in […]
This article is about sequencing batch reactor process which is one of various activated sludge method in wastewater treatment. This is a method consists with a sequence of filling wastewater, aeration reacting, settling, and drawing clarified water (treated effluent). Also, this can be used as advanced wastewater treatments which remove phosphorus and nitrogen. ■ About […]
