Abstract
An oil and grit separator system having twin vortex which uses gravity providing a twin vortex effect to remove sediment and oil from contaminated water. The system is designed to control storm water runoff and reduce the annual suspended solids loading of the granulometric particles. The conception and configuration of the system has a double action vortex. It ensures an optimal treatment level in either light or heavy rain and avoids re-suspension of particles. It also removes, separates and stores floating oil without any possible re-suspension of the matter.
Claims6
An oil and grit separator system comprising:
- a manhole bin having an entry line configured to receive water having oil and sediments and an output line configured to allow water free of oil and sediments to exit the system;
- a flow divider plate configured to direct the water into at least one centrifuge plate, wherein the at least one centrifuge plate is configured to direct the water into at least one funnel configured to induce the contaminated water to vortex to separate the sediments from the water;
- a sediment vault configured to hold the water and separated sediments;
- and,
- an oil storage area positioned in the sediment vault, wherein the oil storage area is confined by an angular plate having a retaining flap downwardly extending from angular plate providing a trap for the oil and an exit for the water, wherein the exit is in communication with the output line.
