Oil/Water Separators

Designed for the removal of small particles, organics, and floating contaminants to protect downstream equipment or meet discharge requirements.

General Description

oil water separationOil water separators (OWS) are used for the separation of free and dispersed (non-emulsified) oil and settleable solids from water. Oil water separators are an effective tool to remove any type of oil lighter than water. Oil/water separators are a simple tool for treating water because gravity is the driving force for the separation.

Oil removal is driven by a unique cross-fluted PVC coalescer. The coalescing pack provides laminar flow and high surface area, which is important to allow the small droplets to coalesce with each other and on the oil-attractive PVC media surface. Once attached, they provide additional surface area to the coalescing media while attracting other small oil droplets with their cohesive properties. This process combines oil droplets until they are large enough to rise to the surface for skimming. H2K Separators are ½ the volume and as little as 1/5 the length of gravity separators. Model sizing is based on the oil/fuel specific gravity, droplet size removal desired and other parameters of the waste stream. H2K oil/water separators are constructed to standards that meet or exceed API Bulletin 421, API Bulletin 1630, UL Subject 2215, and USCG 46 CFR 162.050.

oil water separatorDesign Considerations

  • Flow rate and conditions
  • Oil/water ratio in the inlet water
  • Media Size (two types)
    • Wide – Reduces fouling from solids
    • Narrow – Provides better oil separation
  • Oil disposal method
  • Oil droplet size
  • Specific Gravity of oil

Stoke's law constant of contaminants
Stoke's law is the driving force behind oil water separators. Stoke's Law relates the difference in specific gravities of the two known fluids, to the viscosity for the main fluid. In the case of an oil water separator, water and oil are generally the fluids of concern. Given this information the media size, system flow rate requirement, the size of the oil water separator can be determined.

Construction Options

Fiberglass Construction:

Fiberglass construction is the most common oil/water separators from H2K Technologies. These units perform well where corrosion resistance is required or pH level is strongly acidic or basic. Fiberglass separators are also a good choice in coastal areas where salt would cause rust to steel units.

Stainless-Steel Construction:

Stainless-Steel units can be built to the same spec as steel and fiberglass units, with the advantages of stainless steel. Construction is available in 304 and marine grade 316 stainless steel to match site requirements. Stainless units provide the most durability, longest lifespan, and corrosion resistance in most industrial environments. Internal separation media is available in either PVC or stainless steel.

Carbon Steel Construction:

H2K Oil/water separators are also available in welded steel for higher flow applications where either fiberglass or stainless would be cost-prohibitive. These units come with an industrial epoxy finish to provide protection against the elements. Carbon steel units are typically used where corrosion is less of a concern, but are capable of handling most environments.
