Abstract

An effluent treatment apparatus, and associated methods of use, are provided for treating in a closed-loop configuration a volume of effluent contained in a holding vessel. The apparatus includes one or more treatment tank units arranged to hold a volume of molecular filtering material capable of removing one or more toxic contaminants from the effluent, al least in part, as the effluent contacts the surface areas of the molecular filtering material within each tank unit. A pump unit is provided to draw effluent from the holding vessel and deliver the effluent to selected tank units to effect treatment. The apparatus further includes fluidic conduit structures to fluidically couple the holding vessel, a pre-filter, the pump, and each selected tank unit. The conduit structure forms a closed-loop wherein effluent drawn from the holding vessel is pre-filtered, delivered to each selected tank unit, treated by contacting the molecular filtering material as the effluent flows through the tank unit, and returned to the holding vessel, repeatedly as required for treatment of the volume of effluent. A pressure regulation and bypass arrangement coupled via the conduit structure in a shunting configuration with respect to the tank units may also be provided with the invention to enable the pressure at which the treatment in the tank unit is conducted to be maintained at or below a pre-selected pressure level, even when the flow of effluent through one or more selected tank units is significantly restricted.
