Abstract
The invention provides a method of decontaminating a waste stream liquid of solid particulate and one or more other pollutants, the method comprising the steps of: (i) removing solid particulate contaminant from the waste stream liquid by passing the waste stream liquid through at least one solids trap into a waste stream liquid holding reservoir whereby solid particulate is retained in the at least one solids trap; and (ii) removing one or more other pollutants from the waste stream liquid in the reservoir by contacting the waste stream liquid with at least one contaminant trap whereby the contaminant trap sequesters the one or more other pollutants within the contaminant trap.
Claims24
A system for servicing a grease interceptor for decontaminating a waste stream liquid of solid particulate and one or more hydrocarbon pollutants, the system comprising:
- the grease interceptor comprising:
- at least one reservoir for waste stream to be decontaminated, the reservoir having at least one inlet for receiving the waste stream into the reservoir and at least one outlet for removal of decontaminated waste stream from the reservoir;
- at least one solids trap in direct fluid communication with the at least one inlet for separating solid particulate material from the received waste stream before the waste stream enters into the reservoir;
- at least one hydrocarbon contaminant trap for removing the one or more hydrocarbon pollutants from the waste stream received into the reservoir, wherein the hydrocarbon contaminant trap includes one or more oleophilic sorbent materials for sequestering the one or more hydrocarbon pollutants therein;
- and
- a vacuum means suitable for removing the solid particulate material from the at least one solids trap and the one or more oleophilic sorbent materials from the hydrocarbon contaminant trap.
A method of decontaminating a waste stream liquid of solid particulate and one or more hydrocarbon pollutants in a grease interceptor, the method comprising the steps of:
- (i) removing solid particulate from the waste stream liquid by passing the waste stream liquid through at least one solids trap into a single chamber waste stream liquid holding reservoir, wherein the solids trap is provided in the direct path of the waste stream as it enters the reservoir such that the waste stream liquid flowing through the at least one inlet of the reservoir flows through the solids trap prior to discharge into the reservoir, whereby solid particulate is retained in the at least one solids trap such that the waste stream liquid entering the reservoir for further treatment is substantially particulate free;
- and
- (ii) removing one or more hydrocarbon pollutants from the waste stream liquid in the reservoir by contacting the waste stream liquid with at least one hydrocarbon contaminant trap whereby the hydrocarbon contaminant trap includes one or more oleophilic sorbent materials for sequestering the one or more other pollutants within the contaminant trap;
- wherein the interceptor is configured such that the one or more oleophilic sorbent materials and the sequestered hydrocarbon pollutant are removable from hydrocarbon contaminant trap by a vacuum means.
