wastewaters. The CMAS process is relatively simple to operate but tends to have low organic substrate concentrations(i.e., low F/M ratios)that encourage the growth of filamentous bacteria, causing sludge bulking problems. < Requirement & Assumption >1. 1차 유출수+반송수 Q=15260.3㎥/d2. 포기조 DO=2.0g/㎥3.

bacteria in an oxidation pond.Aeration tankAeration is used to treat tastes and odors, to help remove minerals such as iron and manganese from water, and to remove carbon dioxide from the water. How Does Aeration Work?Scrubbing action: this is caused by turbulence which results when the water and air mix together. The scrubbing action physically removes gases from solution in the water, a

wastewater goes through the system, BOD and organics concentration are greatly reduced. Variations to this method include: adding return sludge and/or in decreasing amounts at various locations along length of the tank; wastewater BOD is reduced as it passes through tank, and air requirements and number of bacteria required also decrease accordingly. Complete Mix: wastewater may be immediately
