Abstract: This invention relates to an improvement in the process of water treatment, particularly where such process involves the treatment of well waters for iron removal by aeration and filtration under pressure. Huge amounts of air are sucked in as drinking water is being withdrawn. Normally, the aeration tank itself provides plenty of holding time for air to do its work. Every drinking water reservoir respirates: Aeration and deaeration of drinking water reservoirs is necessary for pressure equalisation as the water level in the water chamber varies. The efficiency of aeration depends on the amount of surface contact between air and water, which is controlled primarily by the size of the water drop or air bubble. In aeration tank the wastewater is mixed with activated sludge and oxygen is provided to the microorganisms through diffused aeration. METHODS OF AERATION. The resulting âpurifiedâ water trickles out through pipes for further treatment. After sitting for 12 to 24 hours, drain the storage tank through a drain valve or through the distribution system.
