ABSTRACT:
A system for removing volatile constituents (e.g., hydrocarbons) from a liquid (e.g., water) containing the same by which there is a continuous countercurrent contact between the liquid and a forced air flow. Water collected in a reservoir is continuously pumped to the top of a stripping tower where it is dispersed downwardly over packing material. A blower forces air upwardly in the tower so as to remove the volatile constituents that exit the tower with the exit air. Since the water flow is continuous, multiple passes occur through the tower to enhance separation efficiency. Water from the base of the tower returns to the reservoir via overflow from a standpipe. A lower liquid level sensor in the reservoir initiates operation of the water pump to the tower, and an upper liquid level sensor initiates operations of another pump for pressure discharge from the base of the tower to an exterior site. There is a security enclosure to prevent unauthorized access with this enclosure being mounted on a support base for supporting the other components.
