Oil water separator, an equipment in which is used for separating oil and water mixtures into their own respective components. It is important because it is used to ensure that water disposal overboard are within the legal limits while in good working condition and is operating under the MARPOL regulations. In other terms, oil water separator clears the bile water of oily content until it reach he acceptable range for discharge overboard. Also, it is used to prevent spilling of oils during pumping of bilges. The force behind the separation of oil and water is through its difference in densities. The forces of gravity acting on them makes the oil go to the surface and the water to the bottom.
Also, Oil separators utilize to remove oil from bilge drinking water prior to its’ discharged overboard. Normally bilge water is composed of contaminants which incorporate may grades of oil in water as well as suspended solids, rust, chemical substances, detergents, soot, paint chips and cargo dust. If the oil is not separated from bilge water before it is discharged, it may result into an undesirable transfer of squander oil to the maritime atmosphere.
A number of factors affect the satisfactory operation of the marine water separators like its design wherein it contains the simple operating concepts of the separator and the enhancements made for marine context. Another one is operation which is very vital because the operations understanding and approach is generic and primarily based on the products and technical specifications. Bilge manage is also one of the factors that affects the operation. It is crucial to know what goes into the bilge water and it is affected. Lastly, the maintenance and personnel training in which the persons assigned for the maintenance and troubleshooting of the equipment should be endorse properly with the knowledge needed in times of operational needs.
There are different types of oil water separator and each of them has different characteristics made for specific purpose in industries. Treating contaminants such as free floating oil, emulsified oil, and suspended solids is one of the purposes of OWS. In designing and selecting oil water separators, there are parameters to be considered in determining performance. These include, oil droplet size, oil density, water viscosity, feed oil concentration, and feed oil water flow.
Oil water separators (OWS) (marine) are specific for marine industry. It is used to separates oil and other contaminants that can be harmful to the oceans. They are commonly found on board ships where oil is separated to product of shipboard operations called bilge water before the disposal of waste water. Bilge water includes drain water, water from broilers, drinking water, etc. Furthermore, propulsion area of the ship also drains other waste such as fuels, lubricants, hydraulic fluid, solvents, and cleaning chemicals into the Bilge system.
RWO have been manufacturing deck hardware’s for years and still are continuously seeking to improve the range of supply and demands of the present sailing trends and to continue sponsoring and supporting sailboats that are actively racing across the globe.
