Notes

  • This data should be used soley as a guideline for separator sizing.
  • Other known and unknown factors may affect separator sizing. For interior floor drain applications, the international plumbing code may apply and may require a larger separator.
  • Oil / water separators are designed to remove free floating oils and greases as described in our literature. Our oil / water seperators are not designed to remove volatile organic solvents or highly dissolved solids. The use of general detergents will emulsify oils and greases and will not allow them to separate adequatley in our oil water separators. This will lower the oil / water separators effeciency.
  • Many actors effect the proper operation of oil / water separators. Although the sizing utility calculations above are believed to be accurate and reliable, Kleerwater Technologies LLC makes no warranties, expressed or implied, as to concepts or guidance used in this information, or as to the performance of the apparatus represented until reviewed by Kleerwater™ Technologies LLC.
