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.

PureULTRA II UF modules are constructed using highly hydrophilic modified PVDF hollow fiber membrane with a tight nominal pore size of 0.025 micron. The outside-in flow configuration contributes to easier cleaning as it keeps the solids, pathogens, and other foulants on the outside of the fibers. The fiber is designed to handle most feed water sources and tolerate solids loadings while operating within an optimal flux range.

PureULTRA II modules are used for:
- RO pretreatment
- Surface water treatment (plant influent)
- Water reuse
- Tertiary wastewater treatment
- Seawater treatment

BIO-CEL MBR is a cost-effective and scalable solution for meeting challenging effluent requirements for municipal and industrial wastewater treatment.

It creates a cleaner, higher quality effluent than conventional wastewater treatment systems, using up to two times smaller overall footprint due to its high packing density.

The BIO-CEL series is built upon our unique, patented self-healing laminate technology – a proven innovation that has been delivering reliable performance for over 15 years. This revolutionary technology addresses the critical challenges faced by traditional MBR applications, such as membrane durability and fouling, among other key benefits:
- Reliable filtration quality
- Enhanced fouling resistance
- Reduced cleaning frequency
- Minimized energy demand and downtime
- Optimized TCO (total cost of ownership)

iSep 500+ UF modules offer compact, efficient treatment for high-fouling and variable-quality water sources. With an integrated tank design and vacuum-driven spiral-wound membrane, iSep 500+ handles challenging feedwaters such as industrial effluents, river water, and produced water with ease.

Featuring a hydrophilic 0.03 μm PVDF/PES membrane, the system removes suspended solids, oil & grease, and turbidity while delivering consistent, high-quality permeate. Internal aeration and backwash features reduce chemical use and fouling, enabling stable operation even under heavy solids loading—without the need for extensive pre-treatment or large tanks.

The FILTER Line delivers robust, efficient pretreatment to safeguard downstream membrane processes like UF and RO. Designed for diverse feedwaters, from surface and brackish to wastewater and industrial effluents, it ensures optimal membrane performance and longevity.

The FILTER Line includes:
- Cyclon Filters
- Strainers
- Self-Cleaning Filters
- Bag Filters
- Cartridge Filters
- Private labeling options are available
