typical use
Install Pentair X-Flow HFNANO Solution with the Pentair X-Flow HFW1000 membrane elements, it leverages the strengths of hollow fiber technology and nanofiltration (NF) membranes into a sustainable membrane filtration solution.
The X-Flow innovative HFW1000 hollow-fiber NF membrane element is chlorine resistant and backwashable, which helps address the challenges of spiral-wound NF membranes. The X-Flow HFNANO Solution eliminates the need for coagulants to remove dissolved organics from difficult surface water sources.
scope
Pentair X-Flow HFNANO Solution uniquely removes color and organics from drinking water and wastewater and can be used in both municipal and industrial operations. With carefully selected partners, Pentair develops innovative and ready-to-use membrane installations that meet both regulatory and financial KPI’s.
With world-class X-Flow Membrane Solutions and Pentair X-Flow Membrane+ Approach, you’ll gain peace of mind.
Delivering what you and your customers strive for – a chemical free water treatment with one-step nanofiltration.
Fields of application
- 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.
Typical applications
HFNano systems are built when it becomes difficult to treat surface water.- 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
