QILEE Containerized RO Skid Systems

High-Efficiency Desalination for Converting Brackish Water to High-Quality Pure Water, which is designed specifically for brackish water with high hardness, high sulfates, or specific contaminants (e.g., Fluoride, Arsenic).
The QILEE QL-BWRO Series is an integrated solution designed for treating brackish water with high salinity and producing high-purity water. It incorporates multi-stage pre-treatment, precision filtration, the core Reverse Osmosis (RO) desalination process, and post-conditioning within a standard container. It effectively removes dissolved salts, ions, heavy metals, and organic pollutants, producing water quality that far exceeds drinking water standards. It is the ideal choice for brackish water regions, industrial parks, and high-purity water applications.

Core Advantages

High-Efficiency Desalination

Employs high-rejection RO membranes, achieving a removal rate of over 98% for Total Dissolved Solids (TDS), easily converting brackish water into pure water.

Efficient & Stable

Optimized system design and high-quality membrane elements ensure stable operation at high recovery rates, reducing operational costs.

Intelligent Integration

Fully automatic control with an integrated membrane cleaning system to effectively prevent scaling and fouling, extending membrane life.

Plug-and-Play

Containerized design, fully assembled and tested before shipment, significantly reducing on-site installation and commissioning time.

For Custom Sizing and Technical Support

Our engineering team can design optimized RO skid configurations based on your specific water analysis and capacity requirements.

Designed Raw Water & Treated Water Quality

This series is designed for treating brackish water with TDS < 10,000 mg/L and can also be used as a polishing stage after conventional purification systems.

Water Quality Indicator	Designed Raw Water Value (Brackish)	Guaranteed Treated Water Value
Total Dissolved Solids (TDS) (mg/L)	＜ 5,000	≤ 500

Treated Water Quality

The effluent stably meets and exceeds the Chinese "Standards for Drinking Water Quality" (GB 5749-2022), making it particularly suitable for applications with strict TDS and specific ion requirements.

Product Applications
