Membrane filtration technology applied to the production of ethanol from cellulosic materials

The production of fuel grade ethanol has exploded in recent years due to the push to get away from the reliance on fossil fuels such as gasoline. Until just recently, the primary source for the majority of ethanol has been corn. However, ethanol derived from cheaper and more renewable sources such as cellulosic biomass like corn stover, switchgrass, cereal straws and wood chips has emerged as a major factor in this industry.

Environmental applications

Chemical Industry and Process Waste Water Membrane filtration can play an integral role in processing difficult wastewater streams to reduce BOD, COD, and hydraulic loadings as well as producing a clean water source that can potentially be re-used within the plant.

Typical environmental applications are:

  • Dairy and food plant waste streams
  • Potato flume water
  • Polishing of evaporator condensate
  • Recovery and re-use of spent cleaning solutions

Many chemical processes also utilize membrane filtration for:

  • De-salting, diafiltration and purification of dyes, pigments and optical brighteners
  • Clean-up of rinse and washwater streams
  • Concentration and de-watering of minerals such as Kaolin Clay, titanium dioxide and calcium carbonate

Chemical Industry Applications

  • Pigment Production/Recovery
  • Industrial Gelatin
  • Metals Recovery
  • Pharmaceutical Intermediates
  • Industrial Salts
  • Caustic Clarification
  • Paper Additives
  • Process Water Reclamation
  • Polymer Production
  • Specialty Chemicals
  • Kaolin Clay
  • Titanium Dioxide
  • Kraft Black Liquor
  • Spent Sulphite Liquor

  • Paper/Textile Dyes

Waste Water Applications

  • Wheat Starch
  • Tomato
  • Dairy Plant
  • Rendering Plant
  • Lime Process
  • Corn Starch
  • Potato Starch Recovery
  • Stick Water Recovery
  • Egg Process Waste Stream
  • Metals Recovery
  • CIP Chemicals Reclaim
  • Evaporator Condensate Recovery
  • Oily Water Recovery
  • Specialty Chemicals Recovery
  • Syrup/Sweetener Recovery
  • Pasta Starch Recovery

Cross-flow membrane filtration technology is quickly gaining global acceptance as an important manufacturing step in many process industries worldwide. The ability to produce very specific separations / purifications at low or ambient temperatures often make membrane filtration a much more cost-effective technology than more conventional methods such as rotary vacuum filtration or filter presses.

Membrane filtration is a pressure driven technology with pore sizes ranging from 100 molecular weight to 5 microns. The technologies included in membrane filtration are: Reverse Osmosis RO, Nanofiltration NF, Ultrafiltration UF, and Microfiltration MF.
