The COAR™ Sanitary family of membrane elements applies Forward Osmosis (FO) technology to food, beverage, dairy, and other sanitary process streams where gentle concentration and product preservation are critical. By utilizing natural osmotic pressure to drive water removal, COAR™ Sanitary membranes provide an effective alternative to conventional concentration methods while minimizing product stress and helping maintain quality, flavor, and value.

Engineered for hygienic processing environments, COAR™ Sanitary membranes support product concentration, ingredient recovery, and process optimization across a wide range of applications. Their low-fouling cellulose membrane construction promotes reliable operation, simplified cleaning, and extended membrane life, enabling manufacturers to improve recovery rates, reduce waste volumes, and enhance overall process efficiency.

How Do COAR™ Sanitary FO Membranes Work?

COAR™ Sanitary elements use a pioneering membrane process called Forward Osmosis (FO) to concentrate brine and recover resources. FO uses a natural osmotic pressure difference to move water across a semipermeable membrane without the high operating pressures required by conventional water treatment technologies. Water is drawn from the feed stream into a concentrated draw solution, leaving salts, nutrients, contaminants, and other impurities behind.

Because FO relies on osmotic forces rather than high hydraulic pressure, it is particularly effective for treating difficult, high-fouling streams while maintaining stable performance and water flux. This makes FO a valuable technology for water recovery, brine concentration, and Zero Liquid Discharge (ZLD) applications where reliability is critical.
