Product Beschrijving

Stark High-Efficiency LP-4040 Industrial RO Membrane

The Stark STK-LP4040 is a “Low Pressure” (LP) series aromatic polyamide compound membrane element designed for commercial and industrial water treatment applications. It is engineered to deliver high permeate flow while operating at lower pressures, significantly reducing energy consumption and pump operating costs.

This standard 4-inch membrane element (4″ x 40″) is a universal fit for glass fiber or stainless steel pressure vessels, making it an ideal drop-in replacement for existing RO systems.

Key Features and Benefits

  • Superior Salt Rejection: With an average rejection rate of 99.2%, it effectively removes dissolved salts, organics, and bacteria, ensuring high-quality permeate water.
  • High Flux Output: Producing up to 5L/min (approx. 1900 GPD), this membrane maximizes water production efficiency.
  • Energy Saving Design: Operates efficiently at a low testing pressure of 0.9 MPa (approx. 130 psi), lowering the load on high-pressure pumps compared to standard membranes.
  • Durable Structure: Features a robust 7.8 m² effective membrane area with a 31mil-pp feed spacer to minimize fouling.

Ultra-Low Pressure Operation for Maximum Energy Savings

The Stark STK-LP4040 is engineered with advanced “Low Pressure” (LP) polyamide composite technology. Unlike standard RO membranes that require high operating pressures, this model achieves optimal performance at just 0.9 MPa (approx. 130 psi). Why is this a major advantage?
  • Reduced Electricity Costs: Lower operating pressure means your high-pressure pumps don’t have to work as hard, significantly cutting down energy consumption by up to 30% compared to standard membranes.
  • Extended Equipment Lifespan: Lower pressure puts less stress on pumps, pipes, fittings, and O-rings. This reduces the risk of leaks and mechanical failures, leading to lower maintenance costs over the system’s life.
  • Cost-Effective Upgrade: It allows system integrators to use smaller, more affordable pumps for new installations without sacrificing water production volume.

Voordeel TWEE

Superior Permeate Quality with High Flux Technology

Productivity matters. The Stark LP-4040 features an optimized effective membrane area of 7.8 m², delivering a massive permeate flow rate of 5L/min (approx. 1900 GPD). This “High Flux” capability ensures you get more purified water in less time. Uncompromised Purity:
  • 99.2% Salt Rejection Rate: Utilizing a dense polyamide active layer, it effectively blocks dissolved salts, heavy metals, organics, and colloidal particles.
  • Stable Performance: Even with variable feed water qualities (up to 1000ppm concentration), it maintains a minimum salt rejection of 99.0%, ensuring the safety and conductivity standards of your output water.
  • Fouling Resistance: The smooth surface structure and 31mil feed spacer design help reduce the accumulation of contaminants, extending the cleaning cycle (CIP) intervals.
