Koch Membrane :: Reverse Osmosis

Today's leading Cellulose Acetate (CA) membrane was developed by the pioneering FLUID SYSTEMS^® team at Koch Membrane Systems.

The well-established, long-proven line of ROGA^® Cellulose Acetate (CA) membranes developed by the FLUID SYSTEMS^®  pioneers of Koch Membrane Systems, continue to lead the field in specialized applications. In potable water desalination, municipal wastewater, industrial water, color and organic material removal from cold surface water, and in chlorinated water environments, ROGA elements have been turning in a top quality performance for decades.

ROGA^® Proven Performance:
ROGA membrane is the "original" spiral wound membrane - and still a top performer today. With a smooth surface and neutral charge, KMS ROGA CA membranes are produced as ultrafiltration (UL), low pressure (LP) or high rejection (HR) elements. They have been especially developed (UF) to deliver superior resistance in high organic fouling environments, where thin film membranes would be impractical. ROGA membranes perform exceptionally well in new or replacement systems.

In applications requiring chlorine in the feed water to disinfect the membrane, ROGA membranes offer a unique advantage because of their chlorine tolerance. The HR type delivers a 98% chloride rejection rate at medium pressure.

ROGA^® Elements Primary Applications:
•  Potable water desalination
•  Municipal wastewater (sewage) reclamation projects
•  Industrial water treatment and recycling
•  Where chlorine is required for continuous membrane disinfection
•  Removing color and organic material from cold surface water

ROGA^® An Array of Choices:
Ultrafiltration (UF), low pressure (LP) and high rejection (HR) cellulose acetate (CA) membranes in a wide range of diameters and lengths,
In 4" and 8" diameter and 40" or 60" length.
