Tags: Municipal Water | Zhuhai Project | Self-Cleaning Filtration | Smart Water
KEY RESULTS
• 70%+ reduction in labor maintenance costs
• 100% uninterrupted continuous operation
• Self-cleaning cycle completed in seconds
PROJECT BACKGROUND
Zhuhai Water bears the heavy responsibility of ensuring water supply security and comprehensive water environment management for the entire coastal city. During the upgrading and transformation of a large-scale water treatment plant (pumping station), the client urgently needed an efficient, stable, and highly intelligent pre-filtration system — one capable of handling seasonal fluctuations of sediment, algae, and suspended solids in raw water (reservoir/river water), while protecting downstream core treatment processes such as ultrafiltration membrane modules and high-pressure pumps from wear and clogging.
CORE CHALLENGES
1. High Flow & Continuous Supply
Municipal water supply operates on a massive scale. Equipment must perform cleaning and blowdown without interrupting flow, ensuring zero impact on urban water supply network pressure.
2. Sudden Water Quality Fluctuations
Located in a coastal area, Zhuhai regularly experiences typhoons and heavy monsoon rains, causing raw water turbidity to spike dramatically — easily paralyzing traditional static filter screens.
3. Smart Interconnection Requirements
The water group is advancing the construction of "unattended/minimally attended" smart water plants, demanding filtration equipment with extremely high automation control capabilities and remote data transmission functions.
OUR SOLUTION
1. Powerful Suction / Brush Self-Cleaning Technology
The interior utilizes high-strength stainless steel wedge wire screens, paired with a motor-driven, highly efficient cleaning mechanism. When the pressure differential reaches a set value, the cleaning scanner automatically activates, thoroughly removing impurities from the screen surface using minimal water.
2. 100% Uninterrupted Operation
The self-cleaning and blowdown process is completed in just dozens of seconds. During this time, the main pipeline water flow continues normally, perfectly meeting the stringent standards of continuous municipal water supply.
3. Seamless Smart Water Integration
Equipped with a high-end PLC smart control cabinet supporting triple trigger modes — Differential Pressure, Timer, and Manual. Operational status, pressure drop data, and fault alarms are transmitted in real-time to the Water Group's SCADA central control screen via industrial communication protocols.
CUSTOMER VALUE & RESULTS
• Withstood Multiple Typhoons: Successfully handled high-turbidity raw water surges from multiple typhoons and heavy rainstorms, with outlet water quality consistently meeting standards.
• Extended Equipment Lifespan: Effectively protected downstream water treatment equipment, significantly extending the service life of ultrafiltration membranes and other core components.
• Labor Costs Cut by 70%+: The fully automatic self-cleaning function completely freed up manual labor, slashing costs for daily inspections and filter maintenance by over 70%.
• Smart Water Benchmark: Efficient, energy-saving, and intelligent performance provided solid equipment support for Zhuhai Water's benchmark modern "Smart Water" management project.
