QILEE Group has unveiled its latest innovation, the QL-SWTP 900K Series Integrated Surface Water Treatment System. This full-process facility is designed to directly transform river or lake water—even when it is highly turbid and chemically complex—into high-grade industrial process water or potable municipal drinking water.
With a total daily treatment capacity of 900,000 cubic meters, the QL-SWTP 900K integrates pre-treatment, gravity clarification, and advanced nanofiltration (NF) into a single, automated system. It is built 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 regions.
Technical Architecture and Performance
The QL-SWTP 900K operates in a continuous, fully automated manner through three distinct processing zones:
- Zone 1: Pre-treatment: This first stage employs dual-powered rotary drum screens to achieve filtration accuracy between 20 and 100 micrometers. It is supported by an integrated, intelligent PAC/PAM proportional dosing system that optimizes chemical usage.
- Zone 2: Gravity Clarification: Designed for ultra-low operational expenses, this zone uses a zero-energy gravity-flow approach that consumes no electricity. Each module processes 50,000 cubic meters per hour, removing over 95 percent of suspended solids (SS) through natural sedimentation.
- Zone 3B: Advanced Treatment: The final stage incorporates a large-scale nanofiltration (NF) skid with a single-unit capacity of 300,000 cubic meters per day. This phase ensures efficient removal of total organic carbon (TOC), color, and multivalent ions. The NF technology delivers stable, high-quality water 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 using Computational Fluid Dynamics (CFD) simulations. All skid-mounted components are standardized, manufactured, and treated with specialized anti-corrosion coatings at QILEE’s digital factory. Prior to shipment, the equipment undergoes full Factory Acceptance Testing (FAT) to guarantee immediate plug-and-play functionality at the project site.
The modular, skid-mounted design enables fast deployment, cutting on-site installation time by roughly 60 percent compared to conventional concrete water treatment plants. For operations, the system supports fully automated PLC/DCS remote control and allows operators to monitor water quality in real time 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 firms. Key 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 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.”
