LP/ULP22-8040 Vontron Industrial RO Membrane

LP ULP22-8040 Vontron Industrial RO Membrane

n

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.

n

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.

n

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.

n

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.

Installation & Maintenance Guidelines

n

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

n
n

n
• Use proper pre-treatment to control turbidity, iron, chlorine (residual <0.1 ppm), and scaling potential

n

• 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

n

• Use periodic CIP (chemical cleaning) in accordance with membrane manufacturer guidelines

n

• Avoid exposure to harmful oxidants or chemicals outside the recommended pH / chlorine limits

n

• Keep the membrane wet when stored and use preservative solutions (e.g., sodium bisulfite) when not in service

n

• Monitor differential pressure and reject / permeate TDS to detect fouling early
