Ultrafiltration Economy Portable Series

Economy Portable Series

Ultra-Filtration (or U/F for short) uses permeable membranes to separate water-based solutions, emulsions and suspensions. Under pressure, the membranes allow smaller molecules (such as water) to pass through the membrane and larger molecules (like oils) to remain behind. If you generate water-based wastes in your operations, you need to either dispose of the wastes off-site (which can be expensive) or treat them yourself to remove the waste contaminates. U/F is usually the most cost-effective and least labor-intensive way of treating aqueous wastes so the water can be sewered.

  • What happens to the contaminants?
  • With U/F, processing is done in batches, either out of a tank or drum. The liquid being processed is pumped from the tank, through the U/F unit, and back to the tank. This is done as a constantly re-circulating loop. As the liquid passes through the U/F unit, a small amount of water diffuses through the membrane. The volume of waste in the tank drops as its contents become more and more concentrated with contaminants. This continues until no more water can be extracted, at which point the batch is done. The concentrated contaminants are then empties to a drum or tank for eventual disposal. Now the process tank or drum can be re-filled with a new batch of waste.

  • How often do I need to change membranes?
  • One of the beauties of U/F is that the membranes typically last for one to two years. All that’s needed to keep them performing properly is to run a detergent solution through the U/F unit to remove the contaminants that build up on the membrane surface. The dirty detergent can then be transferred to the process tank for cleaning with the next batch if desired. The frequency of cleaning varies with the nature and level of contamination. It can be after every batch, or it could be on a weekly basis. Experience will indicate which works best.

  • How expensive is a U/F system?
  • U/F is almost always more cost effective than the alternatives when compared on a per-gallon basis. Off-site disposal is one of the most costly choices, and it allows third parties to expose you to potential long-term liability. Evaporators are expensive, have very high energy usage costs, and often require permitting.

    The cost of a U/F system depends on the volume of waste you need to process. Typically, as the daily volume goes up, the per gallon system costs decline. Our entry-level machine can process up to 50 gallons per day. Our larger (non-portable) units can handle thousands of gallons per day.
