Second Life membranes
The advanced chemical treatments restore used membranes to optimum performance levels, offering a cost-effective, high-quality regenerated membranes for secondary application that meets the highest standards of reliability, efficiency, and customer satisfaction
These membranes have very high rejection similar to sea water RO membranes ideal for municipal and industrial applications that require monovalent ions removal
These membranes combine high rejection/low energy properties, similar to low energy BW RO membranes ideal for municipal and industrial applications treating brackish water streams (TDS < 18.000 ppm)
These membranes have very high permeability to monovalent ions, similar to NF membranes ideal for municipal and industrial applications that require divalent ions or larger molecules removal
"Second life membranes" refer to end-of-life Reverse Osmosis (RO) and filtration membranes that are chemically or physically restored to achieve secondary utility. By avoiding landfills, these regenerated 8 inch modules are widely repurposed for wastewater treatment, irrigation, and decentralized drinking water systems, providing a highly sustainable and circular water economy.
Primary Applications
- Secondary Wastewater Treatment: Repurposed membranes are frequently integrated into municipal and industrial treatment processes to filter out suspended solids and reduce turbidity.
- Desalination Pre-Treatment: Regraded RO membranes are heavily reused as pre-filters in seawater and brackish desalination plants to remove larger particulate matter before passing the water to new membranes
- Tertiary Wastewater Treatment: Polishing municipal or industrial effluent to remove suspended solids, micro-pollutants, and remaining organic matter.
- Brackish Water Treatment: Desalting lower-salinity water feeds for industrial loops or groundwater systems at lowered operating pressures
- Agricultural Irrigation: Producing soft, clean water streams optimal for farming, digestate treatment, golf courses, and green recreational spaces
- Special applications: some industrial processes “consume” membranes at a faster rate then the normal economic life time of RO modules - "Second life membranes" offer an economical alternative for these solutions
Environmental & Economic Benefits
- Waste Reduction: Processing used RO elements keeps massive amounts of plastic modules out of landfills.
Key Takeaway: For all applications where desalination is necessary but low-cost, high-value filters are required, 2ndLife (Second-Life) Membranes are the definitive way to go!
