WASTEWATER TREATMENT – AERATED PRE-EQUALIZATION TANKS
The tank is divided into two (2) main sections. The first section is the solids retention section, which is separated from the remaining section of the tank by a stainless steel mesh screen. The second section of the tank has the aeration pumps and the dual controlled discharge pumps. The pumps are ontrolled by a time clock or PLC which alternates power to the aeration pumps every two hours. The timer or PLC is adjustable for the amount of programmed ON and OFF time for pump operation. Hand-Off-Auto switches are provided for confirming the proper mechanical operation of the motors or for manually overriding the control circuit.
