How to Choose the Right Separator

 

Above Ground Separators & Clarifiers

Above ground separators are most often used for separating oil and solids, since they are easier to maintain than in-line units. Above ground oil water separators are ideal for most applications, except for spill containment or stormwater runoff.

Liquid to liquid separation with trace amounts of solids

  • OIL: free and dispersed (non-emulsified)
  • SOLIDS: trace amount of settleable solids

Liquid to liquid separation with light amount of solids

  • OIL: free and dispersed (non-emulsified)
  • SOLIDS: light amount of settleable and suspended solids

Liquid to liquid separation with higher amount of solids

  • OIL: free and dispersed (non-emulsified)
  • SOLIDS: high concentration of settleable solids • low concentration of suspended solids

Liquid to liquid separation with heavy oil and high amount of solids

  • OIL: heavy concentration of free and dispersed (non-emulsified)
  • SOLIDS: high concentration of settleable solids and suspended solids

Water with heavy amount of suspended solids

  • OIL: zero or trace amount of free and dispersed (non-emulsified)
  • SOLIDS: heavy concentration of suspended solids

Below Ground Separators

You would want to use a below ground oil water separator for spill containment, stormwater runoff, vehicle maintenance and washing applications, and any application where an in-line separator is required.

In-line separation with solids

  • OIL: free and dispersed (non-emulsified)
  • SOLIDS: light to heavy amount of settleable solids
