Ultrafiltration removes oil and metals to allow the treated water to be acceptable for discharge for an automobile parts manufacturer. A UF system was selected based upon its ability to consistently meet the discharge requirements without chemicals and with limited operator involvement. This 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 thus making this an excellent solution to this problem.
Ultrafiltration uses a membrane to separate suspended and colloidal materials in an aqueous phase. It will normally separate everything that is not soluble and some larger macro molecules that are soluble. Ultrafiltration uses a PVDF tubular membrane that is permeable to perform the separation. One of the uses that demonstrates the usefulness of ultrafiltration is separation of oil in an emulsion from water. In this case, machining coolant oil emulsions can have the oil separated and concentrated, with the water passing through the membrane, and the concentrated oil phase disposed.
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
