QILEE Group has unveiled the QL-SWTP 900K Series Integrated Surface Water Treatment System, a full-process unit capable of directly turning highly turbid and compositionally complex river or lake water into high-standard industrial process water or municipal drinking water.
With a total treatment capacity of 900,000 cubic meters per day, the QL-SWTP 900K integrates pre-treatment, gravity clarification, and advanced nanofiltration (NF) into a single, automated framework. The system is built to serve large-scale municipal water supply projects, water treatment plants for mega industrial parks, river basin water quality restoration initiatives, and pretreatment operations for brackish water desalination in saline-alkali regions.
Technical Architecture and Performance
The QL-SWTP 900K operates through a continuous, fully automated mode that leverages three distinct processing zones:
- Zone 1: Pre-treatment: This initial stage employs dual-powered rotary drum screens to deliver a filtration accuracy between 20 and 100 micrometers. The zone is backed by an integrated, intelligent PAC/PAM proportional dosing system that optimizes chemical application.
- Zone 2: Gravity Clarification: Engineered for ultra-low operational expenses, this zone relies on a zero-energy gravity-flow design that consumes no electricity. Each module processes 50,000 cubic meters per hour, successfully eliminating more than 95 percent of suspended solids (SS) through natural sedimentation.
- Zone 3B: Advanced Treatment: The final processing stage features a large-scale nanofiltration (NF) skid with a single-unit capacity of 300,000 cubic meters per day. This phase ensures highly effective removal of total organic carbon (TOC), color, and multivalent ions. The NF technology guarantees stable, high-quality water production regardless of seasonal variations in raw river water conditions.
Production, Deployment, and Automation
During the research and design phase, QILEE engineers optimize the system’s sedimentation units through Computational Fluid Dynamics (CFD) simulations. All skid-mounted components are standardized, manufactured, and coated with specialized anti-corrosion finishes at QILEE’s digital factory. Prior to shipment, the equipment undergoes complete Factory Acceptance Testing (FAT) to ensure immediate plug-and-play capability at the project site.
The modular, skid-mounted design supports rapid deployment, cutting on-site installation time by roughly 60 percent compared to conventional concrete water treatment plants. In operation, the system enables fully automated PLC/DCS remote control and gives operators real-time water quality monitoring via mobile devices.
Target Markets and Field Validation
The QL-SWTP 900K Series is primarily aimed at municipal water utility groups, EPC contractors, large steel and chemical manufacturing plants, and environmental engineering companies. Geographic focus areas 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 and energy-efficient design has already proven its field viability. 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.”
