The Activated Sludge Reactor (ASR) is an aerobic, suspended growth biological treatment process and the mixed liquor containing the microorganisms which flows from the ASR are settled in a separate clarifier.
Recycled activated sludge is returned from the clarifier to the ASR to maintain the required concentration of suspended growth in the reactor. This process is also used to degrade soluble organic material.
The ASR goes through cycles of aeration and mixing to optimise the oxygen requirements of the microorganisms. This technique is also suitable where nitrogen removal is required and may require a separate anoxic reactor for the denitrification process. Excess biosolids from the ASR are removed by a waste activated sludge pump.
The AeroASR uses Aerofloat’s patent-pending aeration lance design to produce a maintenance friendly system.
Aerofloat has extensive experience in biological treatment of wastewater and can build either the proprietary AeroASR design or conventional ASRs if larger, more traditional systems are required.
