While reverse osmosis is an effective process used to remove common chemical contaminants, pre-treatment through media filtration is often beneficial for water sources having the following physical properties or containing the following contaminants:
- Dissolved iron
- Dissolved manganese
- Organic matter
- Suspended solids.
When these conditions exist, membrane cartridges can become fouled, requiring more frequent cleanings and replacement.
Other common indicators that pre-treatment may be beneficial:
- Premature fouling of membrane cartridges
- Increased costs from additional antiscalant demand
- Increased system costs associated with additional membrane cleanings and change outs
In summary, pre-treatment ensures that influent (feed water) is compatible with the membrane elements while extending the operating cycles prior to cleaning effectively extending the life of the membrane. It also boosts system efficiency, reduces lifecycle costs, and maintains your system’s integrity. Contact us to learn more about your pre-treatment process options.
