We can tailor this 500 LPH RO System with automation, monitoring, or additional disinfection modules to meet your exact water treatment needs.

BWE series Reverse Osmosis (RO) systems are pre-engineered and pre-assembled units with 8” membrane housings for brackish water(higher TDS).The large volumes can help meet your a variety of industrial applications.T hey are designed for overall superior performance, high recovery rates and offer great savings with low maintenance and operation costs.

Multi-Media Filter (MMF)
Our Multi-Media Filter (MMF) is a highly efficient water filtration system designed to remove suspended solids, turbidity, and other impurities from water. Unlike single-media filters, MMFs use multiple layers of filtration media—such as sand, anthracite, and gravel—each with varying sizes and densities.
This layered structure allows for superior filtration, increased dirt-holding capacity, and longer operational cycles.
Multi-Media Filters are widely used in industrial, municipal, and commercial water treatment applications, serving as a crucial pre-treatment step for processes like reverse osmosis (RO) and ultrafiltration (UF). By ensuring cleaner water and reducing maintenance needs, MMFs enhance the overall efficiency of water treatment systems.

AQUALITEK 12TPH Industrial UF Water Treatment Device (UFL-4 Series) delivers high-efficiency, high-throughput ultrafiltration with Automatic Backwash Technology, high fouling-resistance membrane modules for efficient pretreatment and turbidity reduction in industrial and commercial applications.

Membrane Cleaning Systems (CIP system ) play a crucial role in maintaining the efficiency and longevity of RO (Reverse Osmosis), NF (Nanofiltration), and UF (Ultrafiltration) membranes. These systems are specialized solution designed to clean and maintain membranes without requiring their removal from the system. It could effectively eliminate fouling, scaling, and biological contaminants that accumulate over time, ensure optimal performance, enhance operational efficiency, and extend membrane lifespan. By preventing fouling and scaling, membrane cleaning systems ensure optimal water treatment processes, reducing downtime and maintenance costs.
