ULP series (ultra-low pressure) aromatic polyamide RO element is developed by VONTRON for treatment of surface water and underground water. Its operation pressure is about 2/3 of the low-pressure membrane, and the rejection rate can reach 99.5%. Thus it can reduce the investment cost of related pumps, pipelines, containers, and other equipment and the operation cost of the RO system, improve economic benefits.

LP series (low pressure) aromatic polyamide RO element is developed by VONTRON for treatment of brackish water. It has the characteristics of low-pressure in operation, high permeate flow, and excellent rejection performance in removing of solvable salts, TOC, SiO

LP ULP22-8040 Vontron Industrial RO Membrane

The LP ULP22-8040 Vontron Industrial RO Membrane is engineered for superior performance in large-scale water purification systems. Designed to deliver high efficiency, it effectively removes dissolved salts, heavy metals, and organic impurities from various water sources such as borehole, municipal, and industrial feed water. As a result, it ensures clean, safe, and great-tasting water for both commercial and industrial applications.

Furthermore, this Vontron RO membrane operates at low pressure while maintaining high rejection rates, which helps reduce operational costs without compromising water quality. Its robust design allows a longer lifespan and consistent output, making it a reliable choice for continuous use in demanding environments.

In addition, the LP ULP22-8040 features a 99.5% salt rejection rate and excellent chemical resistance. Because of its advanced polyamide thin-film composite structure, it provides stable performance even under fluctuating water conditions.

When paired with a compatible industrial RO system, it enhances productivity and minimizes maintenance downtime. Therefore, it is ideal for industries such as food processing, beverage production, pharmaceuticals, and power generation.

If you want to achieve efficient desalination and consistent water purity, choose the LP ULP22-8040 Vontron Industrial RO Membrane from Puritech — your trusted partner in professional water treatment solutions.

Applications & Use Cases

Because of its high efficiency and low-pressure design, the LP/ULP22-8040 Vontron membrane is well-suited for:

  • Municipal water purification and desalination when feed TDS is ≤ 2,000 ppm
  • Bottled drinking water production
  • Boiler feed water and make-up water systems
  • Food & beverage processing, pharmaceuticals, and clean water loops
  • Mid- to large-scale RO systems needing high flow with reduced pump loads

Installation & Maintenance Guidelines

To get the best from the LP/ULP22-8040 membrane, ensure the following:

  • Use proper pre-treatment to control turbidity, iron, chlorine (residual <0.1 ppm), and scaling potential
  • During commissioning, flush the membrane with low-pressure flushing (15–25 minutes) then high-pressure flushing (60–90 minutes), discarding the initial permeate. prest.ro+1
  • Use periodic CIP (chemical cleaning) in accordance with membrane manufacturer guidelines
  • Avoid exposure to harmful oxidants or chemicals outside the recommended pH / chlorine limits
  • Keep the membrane wet when stored and use preservative solutions (e.g., sodium bisulfite) when not in service
  • Monitor differential pressure and reject / permeate TDS to detect fouling early
