In short, a clarifier oil water separator is designed to remove both heavy suspended solids AND free and dispersed, non-emulsified oil from the oil water mixture.

The removal of solids is especially important in washing applications in the heavy construction, mining and oil and gas drilling industries where the volume of solids in the wastewater is large.

If the water is to be discharged, most sewer authorities restrict the amount of total suspended solids (TSS). If the water is to be recycled and reused onsite, reducing the amount of solids is critical to providing a high quality rinse and wash water.

The design of the clarifier oil water separator starts with an inlet chamber that reduces influent suspended solids, dissipates the energy and begins separation. The water then goes to the next chamber where particles drop down and slide down the inclined plate and join larger previously settled particles in sludge hopper. The water then proceeds through coalescing media where the oil is removed.

So, for washing applications involving heavy solids, a clarifier separator is your best bet for separating oil and solids.
