Abstract
Abstract The disclosure pertains to an oil decontamination and water recycling system which is designed to prevent oil, grease, and fuel contamination of ground or surface water and to return the clean water in a single pass for reuse. Water contamination results from pressure or steam cleaning of grit, scale, oil, grease and fuel contaminated equipment. The system is a closed loop separation, filtration and absorption system which removes these contaminants and most other petroleum products. The free oils are discharged to a holding barrel and the solids are removed from the settlement tank and drained off from the centrifugal separator. The petroleum based contaminants such as oil, grease and fuel are absorbed mechanically by a cartridge filter for easy disposal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
A water decontamination system comprising a first phase cleansing station and a second phase cleansing station, said first phase cleansing station including a multi-compartment tank for receiving contaminated gravity fed water and producing semi-cleansed water, said multi-compartment tank, including baffle means, stabilizing means and absorption means, said first phase cleansing station delivering said semi-cleansed water to said second phase cleansing station through pressurizing means; said second phase cleansing station including centrifugal separator and coalescing means, and additional absorption and filtering means, each of said means being fluidly interconnected.
Claim 2
Dependent Claim
88 words
A water decontamination system comprising a first phase cleansing station and a second phase cleansing station, said first phase cleansing station including a multi-compartment tank for receiving contaminated gravity fed water and producing semi-cleansed water, said multi-compartment tank, including baffle means, stabilizing means and absorption means, said first phase cleansing station delivering said semi-cleansed water to said second phase cleansing station through pressurizing means; said second phase cleansing station including centrifugal separator and coalescing means, and additional absorption and filtering means, each of said means being fluidly interconnected.
Claim 3
Dependent Claim
67 words
The water decontamination system of claim 1 wherein said centrifugal separator and coalescing means comprises a unitary compartment which receives water from said pressurizing means; said water entering said compartment at an angle to impart a swirling motion to the water thereby forcing the release of solids contained in the water and said solids fall by gravity to a collecting chamber at the bottom of said compartment.
Claim 4
Dependent Claim
42 words
The water decontamination system of claim 1 wherein said centrifugal separator and coalescing means includes a centrally located perforated polypropylene pipe which attracts larger globules of oil products which have been coalesced by centrifugal action in said centrifugal separator and coalescing means.
Claim 5
Dependent Claim
77 words
The water decontamination system of claim 1 wherein said multi-compartment tank baffle means, stabilizing means and absorption means includes a first heavy solids and heavy oil removal compartment, a second compartment wherein additional solids are separated from the contaminated water and a third compartment wherein remaining free oil is removed from the water, and storage means for retaining the semi-cleansed water after it has passed successively through said compartments, said storage means being provided with pressurizing means.
Claim 6
Dependent Claim
21 words
The water decontamination system of claim 1 wherein said second phase cleansing station further includes storage means and additional pressurizing means.
