  • Anaerobic Pond in Wastewater Treatment
    DEFINITION ANAEROBIC POND Anaerobic ponds are deep treatment ponds that exclude oxygen and encourage the growth of bacteria, which break down the effluent. It is in the anaerobic pond that the effluent begins breaking down in the absence of oxygen "anaerobically". The anaerobic pond acts like an uncovered septic tank. Anaerobic bacteria break down the organic matter in the effluent, releasing methane and carbon dioxide. Sludge is deposited on the bottom and a crust forms on the surface as show...

  • Aeration Basins in Waste Water Treatment Plants
    APPLICATION HIGHLIGHT Wastewater Treatment Plant Aeration Basins Application: One of the first steps that a Waste Water Treatment Plant (WWTP) will do is shake up the sewage to expose it to air. This causes some of the dissolved gases that taste and smell bad to be released from the water. As organic mater decays, it uses up oxygen. Aeration replenishes the oxygen. The aeration distribution lines at the bottom of the aeration tanks need sufficient airflow to effectively aerate. A typical WWTP...
