What is an Oil Water Separator (OWS) and How does it Work?

In the shipping and maritime industry, waste management is an important part of operations. The waste produced may be a combination of oil and water, which, if released straight into the sea, can pollute the environment and damage the ecosystem. To prevent environmental pollution, the marine industry uses an Oil Water Separator (OWS), a system that separates waste oil and water from wastewater. Furthermore, OWS is an essential device in marine waste management as it is able to store waste oil in tanks (to be brought to land) and discharge filtered water directly to the sea whilst meeting environmental standards.

Basically, the Oil Water Separator (OWS) is a device that functions to separate oil from water based on differences in specific gravity. Oil that has a lower density will float on water, making the separation process easier. With the help of the latest technology, the Oil Water Separator device can work automatically in filtering hazardous waste into water that is safe for disposal into the environment.

Working Principle and Components of Oil Water Separator Device

The Oil Water Separator device works on a simple yet effective principle. When liquid waste flows into the device, oil and water begin to separate naturally due to the difference in their specific gravity. The lighter oil will rise to the surface, while the heavier water will settle at the bottom of the tank. This separation process is then enhanced through several additional stages of filtration for the final result to reach the set standard.

Some of the main components in an OWS device include:

Separation Tank: The chamber where the entire separation process takes place. This tank is made from corrosion-resistant materials to withstand the extreme conditions of the marine environment.

Inlet and Outlet: These channels regulate the process of wastewater entering the tank and discharging clean, separated water at the right rate.

Coalescence Media: This system coalesces small oil droplets into larger particles, making it easier to collect oil from the surface.

Filters and Monitoring Systems: The filter can help filter out solid particles as well as impurities, while the integrated sensor measures the oil content in the water. Thus, ensuring that the discharged water meets environmental standards.

Stages in the OWS Work Process

The following are the stages in the Oil Water Separator (OWS) work process:

Waste Flow: The liquid mixture containing oil and water is flowed into the tank through the inlet, with careful flow regulation to maintain the stability of the separation process.

Gravity Separation: Due to the difference in density, oil automatically floats to the surface while water settles at the bottom of the tank.

Coalescence of Oil Droplets: The coalescence medium helps to coalesce small oil droplets into larger particles, thus facilitating the oil collection process.

Additional Filtration and Monitoring: The filtration system then filters out sediment and solid particles, while sensors monitor oil levels in a timely manner. The data from the sensors ensures that the produced water is below the allowable threshold.

Clean Water Discharge and Oil Collection: Once qualified, the clean water is discharged through the channels provided, while the separated oil is collected for further recycling or treatment.

These stages produce a separation process that is quick, efficient, and meets environmental standards, allowing the OWS device to perform efficiently in various operational conditions.

Types of OWS Devices

There are various types of OWS to satisfy the demands of the marine industry:

Gravity OWS: This system utilizes gravity to naturally separate oil and water. This method is often used on wastes with low to medium oil content.

OWS Coalescer: Equipped with coalescence media, this system accelerates the coalescence of small oil droplets into larger particles, making it ideal for effluents with fine emulsions.

Benefits and Advantages of Using OWS

The use of an Oil Water Separator in a marine waste management system provides a number of advantages. For starters, it helps to minimize the oil content in the wastewater, ensuring that the water discharged into the environment does not pollute the marine habitat. Furthermore, employing the proper oily water waste separator will keep equipment and machinery clean and in excellent operating condition, lowering the risk of damage and high maintenance costs.
