6 One way of treating the waste stream is by recirculating the effluent through a filter (gravel, sand or peat, for instance). The common denominator in such secondary treatment systems is a recirculation tank. A ZCL wastewater tank can be used in any system that requires recirculation of the waste stream. Whether a wastewater customer is installing a new system or is retrofitting an existing system, a ZCL recirculation tank, in which all waste liquids can be stored in one tank, is a superior option. Installing a ZCL recirculation tank can eliminate the need to install a whole new septic system. Recirculation tanks can be designed and manufactured to fit specific requirements for splitter valves and pumping equipment. Whether the system has a hanging pump chamber or a submerged pump mounted on a pump platform, ZCL can provide a recirculation tank and accessories to fit a customer’s specific requirements. If the application requires the use of the entire tank capacity, ZCL also manufactures bottom sumps to meet this requirement. A typical example of a ZCL recirculation tank application is a recently installed 10-foot-diameter, 113,000 Litre recirculation tank at a trailer park that previously had a concrete septic system that needed upgrading because of new regulations pertaining to existing secondary treatment systems. Recirculation Tank Applications Dosing Tank Applications Certain wastewater systems require a dosing tank. A ZCL dosing tank is designed to receive the wastewater from a septic tank at two points in the process — after primary treatment and/or after secondary treatment — and then dispense of the effluent for final dispersal and/or disinfection. A ZCL fibreglass dosing tank allows for the storage of surge capacity in the system and periodic dispersal of doses of effluent into the drain field in one of two ways — either electrically with a pump or hydraulically with a siphon. Each ZCL tank is manufactured with the same structural integrity designed to handle the pressures of continuous filling and emptying of the tank at specified burial depths. A watertight, corrosion-resistant ZCL fibreglass tank is an excellent choice as a dosing tank in a wastewater system.
