MANN+HUMMEL Water & Membrane Solution offers spiral wound membranes designed to meet specific customer requirements, delivering high-performance results.

RO membranes are typically made of thin-film composite (TFC) materials, and can be used for:

• Boiler feedwater

• Industrial process water

• Water re-use

• Polishing effluent from MBR or UF

• Desalination

NF membranes, depending on the modules characteristics, offer a selective rejection of divalent and polyvalent ions while permitting the monovalent ions to pass through membranes. They can be used for:

• Water softening

• Removal of certain contaminants

RO /NF membranes are available in 2.5”, 4” and 8” spiral wound design but also in several other size and configuration.
