Reverse Osmosis RO membrane - Low pressure

ERO-4021 & ERO-4040 Reverse Osmosis Membranes: Pure Water, Lower Energy

Achieve superior water purification with the ERO-4021 and ERO-4040 Reverse Osmosis (RO) membranes, specifically designed for efficient, low-pressure operation in UK tap water applications. These high-performance, low-energy membranes provide an exceptional average salt rejection rate of over 98.5-99% and are the go-to choice for commercial pure water production, including spot-free window washing and general industrial use.

Key Features & Benefits

• High Purity Output: Effectively removes a broad range of contaminants including dissolved salts, heavy metals (lead, arsenic, mercury), bacteria, viruses, organic compounds, chlorine, and nitrates for exceptionally clean water.
• Low-Energy Efficiency: Designed to deliver high permeate flow rates at lower operating pressures, reducing energy consumption and operating costs. Optimum performance is achieved at around 10.3 bar (150 psi).
• Robust & Durable Construction: Features a robust fibreglass outer wrap for enhanced physical protection and an extended operational life.
• Anti-Fouling Technology: The unique anti-fouling layer on the membrane surface minimises organic fouling, ensuring consistent performance and less frequent membrane change-outs.
• High Flow Rates: The ERO-4040 can produce up to 8,350 litres of purified water per day, offering a high-volume, on-demand supply. The ERO-4021 delivers high flow rates suitable for various commercial needs.
• Trusted Performance: Widely used in the UK for applications requiring reliable, high-quality purified water, from window cleaning to process water.

Technical Specifications

The 40" membrane is a replacement for:

Axeon HF4-4040

Filmtec XLE-4040

Osmonics AK4040

Upgrade Your Water Purification System

Whether you're setting up a new commercial RO system or upgrading an existing one, the ERO membranes provide a reliable, cost-effective solution for uncompromised water quality.

Note: The actual system generally includes pre-filters (sediment and carbon) and a membrane housing for complete operation. Ensure correct operating pressure and waste-to-pure water ratios for optimal performance and longevity.
