An automotive parts manufacturer was in need of a system to process oily waste water. An ultrafiltration (UF) system was selected based upon its ability to consistently meet the discharge requirements without chemicals and limited operator involvement. This ultrafiltration (UF) system removes oil and reduces zinc in compliance with discharge requirements.

Ultrafiltration excels at the clarification of solutions containing suspended solids, bacteria, and high concentrations of macromolecules, including oil this making this an excellent solution to this problem.

Automotive Parts Manufacturer Contaminants Removed

  • Biochemical Oxygen Demand (BOD)
  • Oil and Grease (O&G)
  • Suspended solids
  • Zinc
  • Lead

Dynatec Systems industry-leading tubular ultrafiltration (UF) system is used to treat a broad range of industrial wastewater by separating insoluble components from waste streams. As a cost effective and simple solution for separating insoluble components and colloidal contaminants from a waste stream, wastewater UF offers significant advantages over conventional separation. It is a useful process that does not require chemicals or much space to separate insoluble contaminants.

UF is a pressure-driven process that removes the following from wastewater and other solutions:

  • Emulsified oils
  • Metal hydroxides
  • Colloids
  • Emulsions
  • Dispersed material
  • Suspended solids
  • Other large molecular-weight materials

Ultrafiltration systems are also capable of concentrating:

  • Bacteria
  • Some proteins
  • Some dyes
  • Colloidal or emulsified components

Ultrafiltration systems excels at the clarification of solutions containing:

  • Suspended solids
  • Bacteria
  • High concentrations of macromolecules including:
    • Oil and water
    • Fruit juice
    • Milk
    • Whey
    • Electro-coat paints
    • Pharmaceuticals
    • Poly-vinyl alcohol and indigo
    • Potable water
    • Tertiary wastewater

Ultrafiltration offers the following advantages over conventional separation:

  • No chemical required
  • Very little labor required
  • Simple mechanical process
  • Less sludge
  • Ability to concentrate the retentate for beneficial use
  • Less space required
  • Overall lower operating costs

Tubular Configuration:

  • Higher permeate rate
  • Lower rates of fouling
  • Higher concentration of retentate
  • Easier to clean
  • Longer membrane life
  • Low operating cost
