Compact Ultrafiltration Membrane Filter System with 4 GPM Flow Rate – 0.02 Micron ultrafiltration (UF) membrane removes bacteria, viruses, dirt, and other particulates. Ideal for light residential and commercial applications.

The Premiere PS-500 has a 0.02 micron ultrafiltration (UF) membrane which removes particulates and solids like bacteria, viruses, protozoa, algae, dirt, mold, sediment, clay, iron, sand, and more on a microscopic level. It’s a powerful and highly effective filtration system.

With a flow rate of up to 4 gallons per minute, it’s ideal for light residential and commercial application. (For reference, a 4-person household uses approximately 8 – 12 gallons per minute). It operates smoothly at a low pressure and does not require electricity. Since it produces water on-demand, it does not need a storage tank. Best of all, the UF membrane lasts up to 5 years due to innovative technology which lets you easily flush (clean) the UF membrane whenever it gets full of contaminants. Enjoy substantial savings over expensive, short-lived replacement filters or membranes that need to be replaced entirely when they get full!

Additional variations of the PS-500 are available:

• PS-1000 Ultrafiltration Membrane (8 GPM flow rate)
• PS-1000 + Sediment pre-filter – PS-2000S
• PS-1000 + Carbon post-filter for chemicals – PS-2000C
• PS-1000 + Carbon post-filter for chemicals & lead – PS-2000PB

Premiere PS-500 Compact Ultrafiltration System Features and Benefits

Extremely long membrane life (up to 5 years!) – it’s easy to flush (clean) the UF membrane

• Breakthrough system lets you easily flush (clean) the membrane of collected contaminants
• Don’t keep buying expensive replacement filters or membranes you can’t flush – the Premiere PS-500 is truly revolutionary in this sense!
• Membrane should be back-flushed on a regular basis to ensure longest membrane life (3 – 5 years)
• To flush the membrane, simply turn the valve and leave open for up to 15 seconds to fully flush the membrane. (A small amount of water will go to drain while the valve is open)
• Save time and money by replacing filters significantly less often without any drop in water quality
• The membrane-housing is efficiently designed to provide easy backflushing. (When a membrane undergoes a backward flush, its pores are flushed inside out to clean it of contaminants)

Safe, healthy water

• 0.02 micron UF membrane – Filters out solids and particulates as small as 0.02 micron absolute including bacteria, protozoa, cysts, viruses, algae, dirt, mold, silt, colloidal silica, clay, iron, sand, lead particulate, inorganic and organic materials, and more
• Very high effectiveness in removing bacteria (over 99.9999%), viruses (over 99.99%), and protozoa like giardia and cryptosporidium (over 99.95%) from your water
• Eliminates particulates, sediment, sand, silt, colloidal silica, and other solids and particulates as small as 0.02 micron
• The membrane has four o-rings to ensure a seal so that bacteria and other contaminants do not get back into your filtered water
• The UF membrane also removes particulate lead. (Please see our PS-2000PB to reduce soluble and particulate lead).
• Ultrafiltration can remove tannins in water too. However, if you have both iron and tannins present in your water, you will need a separate, adequate pre-treatment filter system to remove the iron. Water with both tannins and iron is a tricky combination that the PS-500 and our other ultrafiltration systems cannot handle on their own. If you have both iron and tannins in your water, please contact us before purchasing a system.

Constant product quality regardless the quality of the incoming water

• Continuous, 4 gallon per minute flow rate (water pressure dependent)
• If there is an influx of contaminants in the incoming water, the PS-500 will still deliver a consistent, high quality of water no matter how bad the incoming water is

Environmentally friendly technology

• No chemicals used
• Zero waste water during the ultrafiltration process
• Breakthrough well water filter system easily takes the place of outdated reverse osmosis (RO) and ultra-violet (UV) systems
• No storage tank or electricity required to operate this system

This system is ideal for light residential and commercial applications including:

• Whole house
• Food service beverages & ice
• Convenience store beverages & ice
• Beverage process filtration
• Schools
• Hospitals
• Hotels
• Home brewing
• and much more

What is ultrafiltration?

Ultrafiltration (UF) is a type of membrane filtration which removes particulates and solids on a microscopic level. A membrane barrier acts like a filter using slight pressure to separate particles like bacteria, viruses, germs, pollen, algae, and inorganic and organic molecules from the water. Ultrafiltration is ideal for residential or commercial applications using either well water or municipal water.

Benefits of ultrafiltration:

• No chemicals required
• Environmentally friendly technology
• Constant product quality no matter the feed quality
• Exceeds regulatory standards of water quality- has over 99.9% bacteria and pathogen removal
• A membrane filter lasts much longer than a conventional filter (years versus months)

Is 4 gallons per minute enough flow rate for your application?

This compact ultrafiltration system is for applications requiring a 4 GPM flow rate or less. Flow rates for a family of four is approximately 8 – 12 gallons per minute but can be much higher for larger families or higher water use. Here’s the flow rates in a standard home:

• Kitchen faucet: 2 – 3 GPM
• Shower: 1.5 – 3 GPM
• Dishwasher: 2 – 4 GPM
• Washing machine: 3 – 5 GPM

If you need more than 4 GPM please check out our PS-1000 which has a flow rate of 8 gallons per minute. Our ultrafiltration systems can be installed side-by-side to provide higher flow rates (i.e., two PS-500 systems would be 8 GPM, three PS-500 systems would be 12 GPM; two PS-1000 systems would be 16 GPM; three PS-1000 systems would be 24 GPM, etc.).

PS-500 Ultrafiltration Well Water Filter System Maintenance

The ultrafiltration membrane should be flushed on a regular basis to ensure longest membrane life. To flush the membrane, simply turn the valve and leave open for up to 15 seconds to fully flush the membrane. A small amount of water will go to drain while the valve is open.

How often you flush the membrane will depend on your water conditions. The ultrafiltration membrane should be flushed at least once per month, and some users may find they need to flush it a few times a month, weekly, or even daily.

In general, you will know it is time to flush the membrane when there is a consistent, noticeable drop in water pressure. At minimum, it still should be flushed at least once per month even if you do not notice any drop in water pressure.

Replacement ultrafiltration membrane filter is the PS-500-MEM – replace once every 3 – 5 years.

Replacement membrane for the PS-500 is the PS-500-MEM

The PS-500 ultrafiltration membrane system is available with a larger flow rate (8 GPM) and as a multistage system with additional filters for added filtration benefits:

• PS-1000 – 0.02 Micron Whole House Ultrafiltration System with up to 8 gallon per minute flow rate.
• PS-1000 + 5 Micron grooved sediment filter (Premiere PS-2000S) – removes suspended particles in your water that can clog the UF membrane quicker and shorten the life-span of the membrane
• PS-1000 + 5 Micron carbon filter with scale inhibitor (Premiere PS-2000C) – removes chemicals; scale inhibitor product stops limescale and stops corrosion
• PS-1000 + 0.5 Micron activated carbon filter (Premiere PS-2000PB) – removes and reduces dissolved lead, heavy metals, chemicals

Attention: Does your water have chemicals, dissolved lead, lots of particulates, and/or iron and tannins?

If your incoming water has chemicals (benzene, chlorine, chloramine, trihalomethanes, volatile organic compounds, methane tertiary butyl ether, pesticides, radon), you should consider a carbon post-filter. Our PS-2000C ($1,620) is a two-stage ultrafiltration system with the PS-1000 membrane and a carbon post-filter too. The coconut shell carbon filters adsorbs harmful contaminants and improve the appearance and taste of drinking water.

If your incoming water has soluble lead (e.g., lead that has leached into water from pipes and fixtures), you should consider our PS-2000PB. While the PS-1000 does remove particulate lead, it does not reduce or remove soluble lead. Our PS-2000PB ($1,795) is a two-stage ultrafiltration system with the PS-1000 ultrafiltration membrane and a carbon post-filter that tackles particulate AND soluble lead too. 

If your incoming water has high amounts of particulates (sand, sediment, silt, silica, iron, sulphur, or other minerals or metals), you should consider a sediment pre-filter for your water. Our PS-2000S ($1,590) is a two stage ultrafiltration system with the PS-1000 membrane and a sediment pre-filter too. A sediment water filter removes suspended particles in your water that can clog up the ultrafiltration membrane and shorten the life-span of the UF membrane.

If you incoming water has both iron and tannins, it’s a tricky contaminant combination that the PS-500 or PS-1000 and our other ultrafiltration systems will not be able to handle on their own. You will need a separate pre-treatment filter system to remove the iron. If you have both iron and tannins in your water, please contact us before purchasing a system.

Please contact us if you have any questions about your water.

Special notes:

• The PS-500 is NOT recommended for water with a high total dissolved solids (TDS) level (i.e.,over 500 ppm), or if you wish to reduce/remove TDS. The ultrafiltration process preserves healthful minerals (minerals make up TDS). If you have a TDS level above 500 ppm or wish to reduce/remove your TDS level, please keep in mind that only reverse osmosis or deionization will reduce and remove TDS in water. Read about total dissolved solids here.
• Taste-wise, if you want to achieve “tasteless” water that is free from total dissolved solids (TDS) and/or minerals (i.e., how some bottled water tastes – or doesn’t taste, rather) you will want to consider reverse osmosis because ultrafiltration preserves healthful minerals which can contribute to how your water will taste.
• Membrane life may vary according to flow rate, inlet line pressure and local water conditions which may require more frequent replacement.
• Since plumbing configurations can vary, you may need to supply additional parts/adaptors in order to connect this system to your plumbing.
• Install the PS-500 before any water softeners that use sodium (salt). This is because some water softeners make hard water “soft” by replacing the calcium and magnesium with sodium. These high levels of sodium break down the membrane so therefore the PS-500 should be installed before any softener.
