Application 01
Ethanol and biofuel dehydration
AZEO-SEP® pervaporation removes water past the 95.6% ethanol azeotrope for fuel-grade and beverage-grade product, without entrainers. The Sarnia bioethanol/ABE refinery hybrid is the related case study.

Food, Beverage & Biofuels
plants and separation, end to end.
Food, beverage, and biofuels applications need both sanitary, traceable fabrication and the right membrane chemistry for the specific feed. We build sanitary 316L vessels and skids with validated cleaning regimes, and we deploy our own membrane platforms for ethanol and biofuel dehydration, protein concentration, beverage and food processing, fermentation product recovery, and distillation optimization. Most delivered work in this sector runs out of PSE Kerteh; the membrane chemistry and process design anchor in Mississauga (Greater Toronto Area).

Application 02
Protein extraction and concentration
Membrane-based concentration of plant- and animal-derived protein streams. Recent build at PSE Kerteh (April 2026, 13-photo project record) for a food-and-bioprocessing client. Sanitary fabrication, FDA-compatible materials.
Application 03
Food and beverage processing
Concentration, fractionation, and clarification of food and protein streams. Completed dairy plant in China (2016), 1,000 m³/day capacity. Sanitary 316L, validated cleaning regimes.
Application 04
Fermentation product recovery
Pervaporation and vapor permeation for recovering ethanol, butanol, acetone, and other fermentation products from broth.
Application 05
Process water recovery for food sites
Closed-loop water recovery for food and beverage plants. AQUA-SEP® recovers process water at less than 10 ppm TDS, allowing direct reuse on hot-water duties or polishing for CIP.
Fabrication scope

Membrane technologies
The right process for the fluid.
Food, beverage, and biofuel feeds split between solvent-bearing vapor (fermentation off-gas, dehydration loops) and process liquid (protein concentrates, food and beverage streams, process water). Pervaporation and vapor permeation handle the first family. Membrane distillation, which Petro Sep runs as vacuum membrane distillation (AQUA-SEP®), handles the second. We pair them when both exist on the same site.
