Oil Water Separation Process Description for Ecoline B Series

Following, we provide technical information and calculations regarding oil water separation with the EcoLine B 3 (50 GPM / 3 L/S flow rate)  oil water separator.

Stokes Law and other considerations as applied to Freytech oil water separators.

The oil/water mixture flows into the tank where there is sufficient dwell time for some of the solids / mud (if any are present) to sink to the bottom of this section of the tank. The oil water mixture now contains fewer solids as it continues downstream to the section of the tank where the coalescing media panel is installed. Some of the larger oil droplets present in the waste stream will start to rise to the surface and form an oil layer or a sheen floating on the surface of the water.
The wastewater still contains small oil droplets which have not had enough retention time to rise to the water surface and this waste stream continues its flow downstream and enters the coalescing media.

What actually separates the oil from the water is our oleophilic media made of washable and durable reticular polyurethane-polyether material. Oil is attracted to this media. As soon as each oil droplet in the waste stream comes into contact with the coalescing media, it is separated and immediately collides with other oil droplets which are also being simultaneously separated.

As these oil droplets continue to collide with each other, they coalesce together forming larger oil droplets and then detach from the media and rise to the water surface because of their specific weight (oil being lighter than water). 

The reticular polyurethane-polyether material which separates the oil from the water has a surprisingly large surface area given its composition and consistency.

The formula for the minimum effective surface of the coalescing media is A = 1.4 x NS m² Surface (in m²) = 1. 4 x Nominal size.
A conventional 50 GPM / 3 l/s treatment flow rate below ground separator has: 3 x 1.4 = 4.2 m2 (45 ft2 ) of minimum required coalescing surface area. The Freytech Inc. EcoLine B-ADD 3 model has  9 m2 (97 ft2) of effective coalescing surface area.

ECOSORP

FOR EMULSIFIED AND DISSOLVED OIL: (ECOSORP BELOW 1 PPM)

The EcoSorp oil water separator is for use to obtain below 1 part per million (PPM) separation efficiencies. It is for use with free or PHYSICALLY EMULSIFIED AND DISSOLVED OIL by adsorption from water. This represents exceptionally clean separation. The EcoSorp requires filter / coalescing media cartridge replacement since it works through adsorption and the media becomes saturated over time (typically once a year). Recommended for use downstream of a Freytech Inc. above or below ground 5 PPM oil water separator to prolong its useful life. The media can absorb up to 22 lbs (10 kg) of oil. Units available with flow rates up to 100 gallons per minute (GPM) / 380 liters per minute (L/M). No electrical power requirements.

Typical Fields of Application

  • For emulsified and dissolved oil. 

HIGH FLOW RATE OIL WATER SEPARATOR

Each XL Separator Panel can effectively treat oily water flow rates ranging from 320 GPM (20 l/s) to 640 GPM (40 l/s). Achieves 5 Part per Million (PPM) separation of free non-emulsified oil. By far, the most affordable method for large industrial oil-water separation since panels can be installed side by side like windowpanes in a submerged cross-wall in locally procured concrete or steel tanks. This unique solution represents a huge advantage over shipping conventional bulky separators since there is no limit to the flow rate that can be treated and the panels are washable and reusable. Maintenance is conducted from above ground making it safer, cleaner, quicker and of course, more affordable. Each panel requires 1 yard / 1 meter of submerged wall space. Optional polishing system available to also separate trace emulsified oil down to 0.1 PPM.

With the optional ADD Skimmer, the oil being separated by the XL Panels is mechanically and automatically collected 24/7 and drained by gravity to a separate receptacle. The skimmed oil will contain only 0.3% of water thus providing the operator with an outstanding 99.7 % concentration of pure used oil. This represents a significant advantage over other skimmers in that the operator no longer has to pay for the separated oil and the excess water to be removed from the separator by septic truck and shipped/ treated in a wastewater treatment plant. The operator can even sell or donate the pure separated oil since it is now possible to skim it free of water from the separator on site.
