What is the function of oil sensing probe on oily water separator?

Sketch of shipboard oily water separator This is known as the collection space. A sensor will then sense the level of oil and it will be dumped accordingly via an oil valve to the dirty oil tank. The remaining oil / water will move down to the fine separation compartment and move slowly between catch plates.

How can an oily water separator separate water and oil?

After wastewater passes through filters to separate out the largest solids, it is funneled into the oil water separator to undergo treatment. In most cases, the wastewater travels across a series of plates, generally on an incline. These plates help to separate oil, water, and sludge into three distinct spaces.

How do you maintain an oil separator?

Oil Water Separator Maintenance

1. Turn off the influent water to the unit.
2. Open the unit cover.
3. Remove any oil and dispose of it in a way that complies with company and legal procedures.
4. Drain the water from the separator.
5. Measure the depth of the leftover solids and write it down.
6. If necessary, dispose of the solids.

What is oily water separator in ship?

marine. A device used to separate oil from oily water mixtures and from the emulsion. Bilge separators are necessary aboard vessels to prevent discharge of oil overboard while pumping out bilges or while cleaning oil tanks.

How does an oil separator work?

How Does it Work? After wastewater passes through filters to separate out the largest solids, it is funneled into the oil water separator to undergo treatment. These chambers help to separate oil, water and sludge into three distinct spaces. The heavy sludge and suspended solids drop to the bottom.

What ppm of oil in water is allowed in OWS?

15 parts per million
As per maritime regulations, the oil content in the water processed from the OWS must be less than 15 parts per million of oil.

How does an oil content monitor determine the oil content inside the pipe by using light?

On a vessel this can be known as the oil content monitor (OCM). These oil content meters work using a light scattering measurement principle. The sample is passed through an optical cell and the light scatter algorithms will calculate the level of oil content, measured by PPM (parts per million).
