Product Introduction

Product Description:

Membrane Material: Modified Aromatic Polyamide (MAPA)

Membrane Type: Reverse Osmosis Membrane - High Flux, High Desalination Rate BW

Outer Wrapping Type: Fiberglass Reinforced Plastic (FRP) Wrapping

Flow Channel Type: Diamond-Shaped Flow Channel 28mil/31mil/34mil, etc.

Membrane Welding Method: Multi-page/Short-page Welding

Application Scenarios: Upgrading Tap Water Quality, Drinking Water, Industrial Pure Water/Ultra-pure Water, etc.

Product Advantages:

Utilizes imported membrane sheets combined with proprietary modification patents to eliminate microscopic defects on the membrane surface, enhancing the membrane's rejection efficiency and flux while reducing pollutant deposition on the membrane surface, improving anti-fouling performance;

Employs multi-page/short-page welding technology to increase the utilization rate of effective membrane area, eliminate dead zones, and thereby enhance water production flux.

The ROA series membrane elements combine the advantages of traditional polyamide composite membranes, such as low pressure, high flux, and high desalination rate, with excellent anti-fouling properties, offering outstanding cleaning durability. Suitable water sources include pretreated surface water, groundwater, river water, and tap water. Widely used in water treatment applications, such as drinking water, municipal tap water quality upgrading, and industrial pure water/ultra-pure water production.
