QILEE Group has officially unveiled the QL-SWTP 900K Series Integrated Surface Water Treatment System, a comprehensive facility capable of transforming heavily turbid and chemically diverse river or lake water directly into premium industrial process water or potable municipal water.
With a total processing capacity of 900,000 cubic meters per day, the QL-SWTP 900K integrates pre-treatment, gravity clarification, and advanced nanofiltration (NF) within a single, automated platform. This system is designed to support large-scale municipal water supply initiatives, water treatment plants for major industrial parks, river basin water quality improvement projects, and pre-treatment operations for brackish water desalination in saline-alkali areas.
Technical Architecture and Performance
The QL-SWTP 900K functions through a continuous, fully automated process featuring three specific treatment zones:
- Zone 1: Pre-treatment: This first stage employs dual-powered rotary drum screens, delivering a filtration accuracy ranging from 20 to 100 micrometers. An integrated, intelligent PAC/PAM proportional dosing system supports this zone to fine-tune chemical usage.
- Zone 2: Gravity Clarification: Built for minimal operational expenses, this zone relies on a zero-energy gravity-flow design, consuming no electricity at all. Each module handles 50,000 cubic meters per hour, eliminating over 95 percent of suspended solids (SS) via natural settling.
- Zone 3B: Advanced Treatment: The final step incorporates a large-scale nanofiltration (NF) skid with a single-unit capacity of 300,000 cubic meters per day. This stage ensures efficient removal of total organic carbon (TOC), color, and multivalent ions. The NF technology guarantees stable, high-quality water output despite seasonal variations in raw river water quality.
Production, Deployment, and Automation
During the research and design phase, QILEE engineers optimize the system’s sedimentation units using Computational Fluid Dynamics (CFD) simulations. All skid-mounted parts are standardized, manufactured, and coated with specialized anti-corrosion finishes at QILEE’s digital factory. Prior to shipping, the equipment undergoes complete Factory Acceptance Testing (FAT) to ensure immediate plug-and-play functionality at the installation site.
The modular, skid-mounted configuration allows for rapid deployment, cutting on-site installation time by roughly 60 percent compared to traditional concrete water treatment plants. For operations, the system supports fully automated PLC/DCS remote control and offers operators real-time water quality monitoring through mobile devices.
Target Markets and Field Validation
The QL-SWTP 900K Series is primarily aimed at municipal water utility groups, EPC contractors, large-scale steel and chemical manufacturing facilities, and environmental engineering firms. Key geographic regions include large coastal industrial zones, Southeast Asia, Central Asia, and the Middle East—specifically major EPC infrastructure projects in Saudi Arabia and the United Arab Emirates (UAE).
The automated, energy-efficient design has already proven its effectiveness in the field. A project manager overseeing an overseas municipal water supply project remarked: “QILEE’s gravity system has performed exceptionally well in remote areas. It not only saved significant electricity costs but also solved the challenge of limited local maintenance personnel through its fully automated design.”
