RO membrane replacement service | TMH20-400 Ultra Low Pressure High Salt Rejection RO

Product Introduction

Complete liquid filter and full water treatment component solutions form our one-stop service system, and our core business covers reliable RO membrane replacement service for all sizes of brackish water RO equipment. Many water station operators and industrial plant managers face common troubles including declined permeate flux, rising conductivity, high power consumption and frequent membrane fouling after long-term operation, and timely RO membrane replacement service can thoroughly solve these persistent water quality problems.

TMH20-400 from high-efficiency TMH series is our top recommended replacement model, featured with ultra low pressure and high salt rejection. Compared with old, aging standard RO membranes, it delivers stable desalination efficiency while lowering overall system operating pressure, helping clients save continuous electricity expenses after replacement. Our RO membrane replacement service includes on-site inspection, old membrane removal, new TMH20-400 installation, system debugging and post-service maintenance guidance, providing full support for commercial drinking water stations, food factories, electronics manufacturing workshops and municipal well water purification projects.

Working Principle

TMH20-400 adopts spiral-wound thin-film composite polyamide structure, the core design that supports its ultra-low pressure and high salt rejection performance after RO membrane replacement service. Its hydrophilic active layer reduces water penetration resistance greatly, so pure water can pass through under mild operating pressure, while salts, colloids, bacteria and heavy metal ions are intercepted by molecular screening and electrostatic repulsion. Internal low-resistance corrugated feed spacers create stable turbulent flow to reduce concentration polarization and slow scaling and biofouling, extending the service cycle after replacement. When you choose our RO membrane replacement service and upgrade to TMH20-400, the optimized winding structure maximizes effective membrane area without increasing flow loss, balancing sufficient water output and low energy consumption for long-term stable operation.

Technical Parameters

TMH20-400 is standard 400-size brackish RO element, perfectly compatible with all mainstream 400 membrane housings, which makes it the most suitable option for our RO membrane replacement service. It maintains over 99.2% stable salt rejection under standard test conditions, with steady permeate flow matching daily water demand of small and medium pure water systems. The ultra-low pressure operating range lessens the load of high-pressure pumps and cuts power consumption obviously. For cleaning tolerance, continuous operation pH ranges from 2.0 to 10.0, cleaning pH 1–12 and maximum cleaning temperature 45°C, compatible with most industrial cleaning chemicals. The maximum feed water SDI is limited to 5, so we will inspect and check your pre-treatment liquid filter during our RO membrane replacement service to avoid rapid fouling of new TMH20-400 elements. All parameter test reports will be handed over to clients after replacement construction for later system maintenance reference.

Product Advantages

The biggest benefit of choosing TMH20-400 in our RO membrane replacement service is its outstanding energy-saving performance as a TMH series ultra-low pressure model. It can reduce pump power consumption by 20%–30% versus aging traditional membranes, lowering long-term operation costs for end users. It retains stable high salt rejection even after multiple cleaning cycles, avoiding repeated replacement work within a short period after our RO membrane replacement service. The universal unified size realizes plug-and-play replacement, no need to modify existing pressure vessels or pipelines during construction, shortening the whole replacement downtime and minimizing production loss for industrial customers. Besides membrane supply and installation, our RO membrane replacement service also provides regular maintenance reminders, standardized cleaning operation tutorials and one-year technical follow-up support, forming a complete after-sales guarantee system for every client.
