Oily Water Separator Working Principle

Oily water separator piping diagram.

Oily water separator working principle. The fundamental principle of separation by which oil water separators work is the difference of gravity between oil and water. Separator capable of achieving 15 ppm on type c emulsion. The separator principle can also be used to separate liquids of different densities such as oil droplets in water or water droplets in oil. The principle of operation of ows is the gravitydifference between oil and water.

In oily water mixtures the oil exists as a collection of globules of various sizes. Oily water separator working principle or principle of operation. Oil goes to the sludge tank or waste oil tank and the water goes overboard or in the grey water tank. The international maritime organization imo publishes regulations through the marine environment protection committee mepc.

Construction and working of oily water separator ows ows consists of mainly three segments. It has a centrifuge filter that roughly divides water from oil due to difference in density and then after that comes another finer filter which keeps the oil in it self. Disk stack separators accelerate the separation process significantly. The force acting on an oil globule causing it tomove in the water is proportional to the difference in weight between the oil particleand a particle of water of equal volume.

Oily water separator ows principle and working. Among all machinery oily water separator ows is given a unique status because of it function and penalties that may imposed because of its irregularities to the ship owner manager and criminal punishment to seafarer under whose duty oily water separator comes. It s more complicated it this covers the basic operation. The ocm must activate and sound an alarm whenever freshwater is used for cleaning or zeroing purposes.

The oil exists in oily water mixtures as a collection of globules of various sizes. The main principle of separation by which commercially available oil water separators function is the gravity differential between oil and water.
