5 Stages Of Oil Water Separation Diagram

5 Stages of Oil Water Separation Diagram

  1. The free oil (150 micron in size or greater) is separated in the inlet quiescent zone.
  2. The settleable solids will flow downward into the hopper section for removal.
  3. The suspended solids and dispersed oil will flow upward through the inclined plates
    section, where most of the suspended solids will slide down the plates into the hopper.
  4. The remaining suspended solids and dispersed oil will flow into the separation
    compartment where the coalescing plates will separate the oil 30 micron or greater to
    the surface for removal .
  5. The flow of water will go over the overflow weir plate into the clean water compartment
    and then discharge to the sewer.

Food processing procedures are as varied as the food produced! The processing and packaging procedures for spaghetti sauce are a lot different from those of sausage, cheese and bread. And, each process produces their own unique waste streams.

That’s where we come in. We can work with your staff and custom-design a comprehensive washing and water treatment system based on your needs.

If you have to wash machinery, piping, conveyors, shelving or tanks, we can help you with pumping and heater packages featuring manual, automated and Variable Frequency Drive controls. A Variable Frequency Drive (VFD) system is one of the most cost effective units to run and maintain and allows multiple users at the same time. Different heating packages can be paired with the pumping and pressure washing systems so that you get the proper water temperature for your washing operation. Foaming, chemical injection and ozone disinfection systems can also be added to the washing systems, if required.

We can help you treat the wash water so that it can be properly discharged. If the washing process produces solids, we have a range of solutions to first separate the solids from the wastewater. After the solids are removed, we can process the water through our wastewater treatment systems.

We provide the following equipment:

Issue: An equipment rental company was expanding and they moved into a new facility
without a wash pad. There was plenty of indoor space but no outdoor space to put in a
new wash pad. The property owner did not want them to cut concrete or substantially
alter the property but our client still needed be able to wash their equipment onsite,
contain the water and discharge it properly to the sewer.

Solution: For a complete wash system, we recommended installing a SPT-10 Clarifier
Oil Water Separator System
, an industrial-grade electric heated water pressure washer
with two portable hose reels, and a portable wash containment pad.
The portable wash pad allows them to wash as much as possible without any major
modifications to the property. They will also be able to move the entire system to a new
facility, if needed. The wash pad was equipped with pedestrian grating along both sides
so that the service personnel can work safely on a dry surface!

Oil Water Separator
The system removes the floating oils from the top of the water surface and directs the water continuously into the oil water separator.

“Our washing operation used to dump 3,000 to 5,000 gallons of process water down the sewer each day because it was contaminated with petroleum oil and wax. Not only did we lose this water in the middle of the worst drought in history but the heat energy it contained as well. We also risked plugging up the city sewer system.

With the help of Wash Bay Solutions, we designed a system using a floating oil skimmer on a hose, a non-emulsifying air pump, and a coalescing stainless steel oil water separator.

The system removes the floating oils from the top of the water surface and directs the water continuously into the oil water separator. The unit produces water so clean that we can use it in our boilers and cooling towers. Zero water is now sent down the sewer.”

Clarifier Oil Water Separator in Mexico
The clarifier oil water separator used for the mining company in central Mexico.

Problem: A gold mine in central Mexico was modifying their vehicle maintenance facility and adding a wash bay for their heavy mining trucks and vehicles covered with solids, dirt, oil, and grease. The mining company contacted an engineering firm in Arizona who then contacted us for our wash bay expertise.

Solution: We worked with the engineering firm to help design the wash bay with the proper pad layout to accommodate the enormous vehicles, substantial wash water volumes and large amounts of solids. We also had to account for rainwater volumes since their wash bay was uncovered.

Our SPT-50 Clarifier Oil Water Separator System was a perfect fit since it was designed for treating wash water from industrial washing operations with large solids concentrations. It includes a stainless steel clarifier oil water separator that has both a clarifier section, which will remove all settable solids and an oil water separator section, which will remove all non-emulsified oil from the waste stream.

During construction of the wash pad and installation of the SPT-50, we continued to work with the engineering company so insure all tasks were completed properly. We provided all manuals and documentation in both Spanish and English so that as little information as possible was lost in translation. The client has reported that the SPT-50 has been working very well since installation.

In many cases, a below ground oil water separator is the best option due to space restrictions and layout. You can use gravity to drain into a below ground system and then into the sanitary sewer system so there is no need for pumps and controls. In other cases, a below ground system has been previously specified and it is not possible to change the specifications.
