Emerging filtration approach
Pentair developed hollow fiber nanofiltration technology that makes it possible for you to:
- remove micobiology and dissolved organics from surface water
- apply a sustainable and environmental safe solution
- help decrease the use of chemicals and energy that is required to treat your surface water
- reduce organic impurities that cause color, odor, and bad taste
As the wastewater from hollow fiber nanofiltration does not contain chemicals or increase in minerals, it can potentially be returned to the environment without further treatment.
Typical applications
- Where sustainable operation with very low environmental impact is required
- Relatively small-scale operations in remote locations with NOM and color issues
- Tourist locations with seasonal occupation, such as visitor centers
- Water plants without operating personnel that require a high degree of automation
When do you choose hfnano?
- Feedwater color: up to 100 Hazen units
- Feedwater TOC (Total Organic Carbon): up to 50 mg/l
- Low salinity, low hardness
- Microbiological contamination requiring multiple barriers (e.g. combining NF with UV and chlorine)
While the above is a good indication of surface water conditions that warrant the choice for HF Nano, the ideal solution is determined by your site-specific conditions and your water quality. In general, flow demand and the availability of proper sludge discharge facilities drive the choice between coagulation/ultrafiltration and nanofiltration.
