Abstract
A retrofit system for biological treatment sanitation vaults wherein evaporation of the liquid waste is accelerated by locating a conduit within the waste receptacle into which only liquid may flow and evaporate within the conduit in the air flowing therethrough. A double conduit system substantially connected in parallel may be used to evaporate liquids accumulating in vaults receiving heavy use for short durations as a float operated air control system permits the most effective utilization of the air movement through the conduit circuit as automatically controlled by the liquid level.
Claims13
A retrofitable waste treatment system for waste vaults, the vault comprising a receptacle receiving liquids and solids having a substantially horizontal bottom, upstanding sides and an upper region, comprising, in combination, a conduit system within the receptacle having an evaporation portion, an inlet portion and an outlet portion, said evaporation portion being substantially horizontal and being located adjacent the receptacle bottom for exposure to liquid within the receptacle, liquid pervious filter means defined in said conduit system evaporation portion permitting liquid within the receptacle to enter said evaporation portion while excluding solid waste therefrom, and air flow inducing means associated with at least one of said inlet and outlet portions producing air flow through said evaporation portion to evaporate liquid therein.
A retrofitable waste treatment system for waste vaults, the vault comprising a receptacle receiving liquids and solids having a substantially horizontal bottom, upstanding sides and an upper region, comprising, in combination, a conduit system within the receptacle having an upper and lower evaporation portions, an inlet portion and an outlet portion, said inlet and outlet portions being in communication with both said upper and lower evaporation portions, said evaporation portions being substantially horizontal, said lower portion being located adjacent the receptacle bottom and said upper portion being located above said lower portion, liquid pervious filter means defined in said upper and lower evaporative portions permitting liquid within the receptacle to enter said evaporative portions while excluding solid waste therefrom, air flow control means located within said upper portion controlling air flow therethrough in dependence upon the liquid level within the receptacle, and air flow inducing means associated with at least one of said inlet and outlet portions producing air flow through said evaporation portions to evaporate liquid therein.
