ULP 4021 Commercial RO Membrane

Introducing the ULP-4021 950 GPD Commercial RO Membrane, a highly dependable choice for water filtration in commercial drinking water systems. These Reverse Osmosis membrane elements are renowned for their consistent performance, made possible through advanced membrane technology and automated fabrication. Shipped dry for ease of handling and extended shelf life, our ISO 9001-rated membranes operate at 60 PSI and can purify approximately 20% more water than competing elements at the same pressure.

The ULP 4021 standard flow membrane system is designed to produce 950 gallons per day (GPD) at an operating pressure of 150 PSI. However, if you reduce the incoming city water pressure to a range of 60 to 80 PSI, the reduced pressure will result in a lower permeate flow rate. In this case, you can expect the permeate flow to be approximately in the range of 400 to 500 GPD, depending on the specific incoming low pressure applied. We recommend replacing your membrane every two years.

Key Features:

  • Effectively removes particles down to 1/10,000th of a micron, eliminating 98% of impurities, including organics, inorganics, and chemicals.
  • Maintains stable, high rejection of contaminants, even with high TDS water sources.
  • Utilizes advanced membrane technology with an innovative thin-layer composite membrane design, resulting in more consistent performance and less fouling, necessitating fewer cleanings and replacements.
  • Ensures 100% dry storage for an extended shelf life.

General Guidelines:

  • Discard the initial permeate from the first full tank, avoiding its use for drinking water or food preparation as it may contain carbon fines and manufacturing by-products.
  • Keep the membrane moist at all times after initial wetting.

  • For extended system shutdowns, it's recommended to immerse membrane elements in a preservative solution to prevent biological growth.
  • While the membrane resists short-term contact with chlorine (hypochlorite), prolonged exposure should be avoided to prevent damage.
  • Strict adherence to the operating limits and guidelines outlined in this bulletin is essential to maintain the limited warranty.

The ULP-4021 membrane is an ideal choice for commercial reverse osmosis systems, providing top-tier filtration and reliable performance for a range of applications. They fit standard 4" x 21" membrane housings, whether stainless steel, PVC, or fiberglass.

Applications:

This membrane is suitable for residential reverse osmosis systems, schools and educational institutions, commercial establishments, such as restaurants, coffee shops, small-scale food processing facilities, office buildings, hospitals and healthcare, ice machines, public water dispensers, manufacturing and processing, recreational facilities, and more.

XLP 4021 Commercial RO Membrane

Introducing the Max Water XLP-4021 800 GPD Commercial RO Membrane, a specialized solution tailored for maple sap filtration.

Best for Maple Sap Filtration:

Our XLP-4021 membrane is your ideal choice for filtering maple sap, allowing for a greater flow while effectively screening out impurities. As concentration increases, it can pass small amounts of sugar.

For more in-depth guidance, check our PDF file A Sap to Syrup Guide.

The XLP 4021 membrane is designed to produce 800 gallons per day (GPD) at an operating pressure of 100 PSI. However, if you reduce the incoming city water pressure to a range of 60 to 80 PSI, the reduced pressure will result in a lower permeate flow rate. In this case, you can expect the permeate flow to be approximately in the range of 480 to 640 GPD, depending on the specific incoming low pressure applied. We recommend replacing your membrane every two years.

Key Specifications:

  • 800 Gallon Per Day Membrane certified to ISO 9001 standards.
  • Removes particles down to 1/10,000th of a micron, eliminating 98% of impurities including organics and inorganics.

Performance Highlights:

  • Ensures stable, high rejection of impurities, even with high TDS water sources.
  • Employs advanced membrane technology with an innovative thin-layer composite membrane design.
  • Maintains more consistent performance with less fouling, requiring less frequent cleaning and change-outs.
  • Stored 100% dry, maximizing its shelf life.

Guidance and Tips:

  • Discard the initial permeate from the first full tank, avoiding its use for drinking water or food preparation, as it may contain carbon fines and manufacturing by-products.
  • Keep the membrane moist after initial wetting.
  • For extended system shutdowns, it's recommended to immerse the membrane elements in a preservative solution to prevent biological growth.
  • While the membrane resists short-term contact with chlorine (hypochlorite), prolonged exposure should be avoided to prevent damage.
  • Strictly adhere to the operating limits and guidelines outlined in this bulletin to maintain the limited warranty.
