## Abstract

Disclosed are remote oily water treatment systems, including systems and related methods of remote oily water treatment with point-of-treatment discharge of treated water. In a preferred embodiment, (a) oily water is treated at a location proximate to where the oily water by passing the oily water through a tank containing a medium defined by at least one polymer mixed with activated carbon and (b) treated water is discharged at the point-of-treatment of the oily water.

## Claims

### Claim 1

A water treatment process comprising the steps of:
a. receiving oily water in a receiving station that features a spill containment pan and that is located on land and adjacent to an inland water way, wherein the oily water was generated or collected at the inland water way that is a lake, stream, or wetland;
b. metering the oily water received in the receiving station;
c. passing oily water through a screen or bag filter to remove solid waste and debris consisting of garbage, rags, and rock;
d. collecting the oily water in a storage tank that is self-supporting without framework and that has a three to five-thousand-gallon capacity;
e. separating the oil from the oily water via an oil-water separator or by a settling tank wherein an amount of oily water is either (a) settled into an oil stream and a water stream or (b) provided through an oil/water separator to create the oil stream and the water stream;
f. passing
i. the water stream through a fiberglass, industrial sand filter to remove solid waste and debris and
ii. the oil stream to a holding tank;
g. passing the sand filtered water through flocculation tank or coagulation tank to promote agglomeration and settling of particulate wastes, wherein the flocculation tank or coagulation tank comprises flocculation agents, coagulation agents, and metal particles;
h. passing the flocculated water into a settling tank to produce water and agglomerated and settled particulate waste, where the agglomerated and settled particulate waste is called “sludge”;
i. separating water from the sludge via a filter press, wherein the filter press de-waters the sludge to create pressed water and pressed sludge, wherein the pressed sludge is provided to a bin before being disposed of or destroyed, and wherein the pressed water is provided to a flush storage tank with two to three-thousand-gallon capacity and translucent sidewalls and recirculated into the water stream;
j. passing the water stream through polyester-coated steel five-foot-tall in-cage cylindrical media tanks sized with a seven-foot diameter for cleansing the water to a particular purity;
k. passing the water stream through an ultraviolet light treatment to purge any biological materials in the water;
l. placing the purged water in holding tanks with a liquid level gauge and visual and sound alarms; and
m. discharging the water into the inland water way that is a lake, stream or wetland.

### Claim 2 (depends on 1)

The process of claim 1 wherein the media tanks are filled with a polymer bond media mixture comprising at least one polymer mixed with activated carbon.

### Claim 3 (depends on 2)

The process of claim 2 wherein the flocculation is ballast enhanced using ballasting agents, including metal particles.

### Claim 4 (depends on 3)

The process of claim 3 wherein the storage tank, oil-water separator, screen or bag filter, holding tank, sand filter, flocculation tank or coagulation tank, settling tank, media tanks, filter press, ultraviolet light treatment, and holding tanks define a kit that is assembled on-location and further comprising the step of assembling the kit.

### Claim 5 (depends on 4)

The method of claim 4 wherein the kit is assembled on any one of the following items selected from the group consisting of a ship or other vessel, a shipping container, a truck trailer, or a portable container that is deliverable via helicopter or drone.

### Claim 6 (depends on 5)

The process of claim 5 further comprising the steps of:
delivering an assembled kit to the inland water way that is a lake, stream, or wetland;
moving the oily water through the assembled kit; and,
discharging an effluent to the inland water way.
