Each filter set operates in two stages: forward filtration and backflushing. The two filter sets work alternately, with the process automatically managing filtration, cleaning, and排污 simultaneously—eliminating the need for manual cleaning and completely preventing clogging.

Key features:
◆ Expertly crafted with durable equipment: Built using advanced German manufacturing equipment and technology.
◆ Premium materials used: The part in contact with water is made from special-grade stainless steel.
◆ High heat exchange efficiency: ≥80% , utilizing large-scale heat exchange and carefully considering the flow direction and duration of the water being exchanged.
◆ Unmanned Operation: Designed with an advanced, fully automated operation mode.
◆ No manual cleaning or maintenance required: An automatic backwash cleaning system has been designed to alternately and cyclically perform backwashing for efficient waste removal.
◆ No scale formation: The buildup of scale can severely impair heat exchange efficiency, but our unique fluid-control design effectively prevents scale from forming.
◆ Comprehensive data reports and operating curves: By accessing the computer, users can view various data such as energy savings, temperature, and pressure, along with detailed operating curves, enabling remote monitoring, maintenance, and management.

Work流程:
◆ Forward operation: B1 (B2)-G1-K1-G2 Positive Filter - K5 - Heat Exchanger - K8-G3 Backwash and Cleaning – K4-2# Wastewater Pond.
◆ Reverse operation: B1(B2) - G1 - K2 - G3 forward filter - K6 - Heat exchanger - K7 - G2 backwash cleaning - K3 - #2 Wastewater Pond.

Electrical System

◆ The electrical system consists of sensors, a variable frequency drive, and a PLC. Composed of a touchscreen and other components, it features a fully Chinese-language human-machine interface for operation, program control, multi-point signal acquisition and display, as well as computer-based and remote real-time monitoring.
◆ The all-Chinese human-machine interface utilizes Siemens products from Germany, allowing various data parameters, curves, and fault alerts to be displayed directly on the interface’s touchscreen.

Reversing Valve Assembly

◆ The reversing valve assembly consists of multiple valves controlled automatically by a program, enabling forward filtration as well as backwashing for debris removal and discharge. It features reliably functioning, long-lasting valves imported from South Korea.

Particle and Fiber Filter

◆ The system features two sets of filters that effectively remove particulates and fibrous debris from wastewater. Each filter set operates in two stages: forward filtration and backflushing. The two filter sets work alternately, with the process automatically controlling filtration, cleaning, and排污 simultaneously—eliminating the need for manual cleaning and preventing clogging altogether.

Fully Automatic Filter Cleaner

◆ The filter is durable and long-lasting—no replacement needed for its entire lifespan.
◆ Suitable for various raw water qualities and water usage requirements.
◆ Fewer wear parts, no consumables, low operating costs, and simple operation and management.
◆ Automatic self-cleaning with continuous flow.

Clearwater Inlet

◆ The all-around wrapped capillary tubes by Qing Shui can effectively absorb heat.

Capillary

◆ The capillary is meticulously crafted from a special material with a highly polished inner surface, offering excellent corrosion resistance and rapid heat absorption. As a result, wastewater flowing through the capillary efficiently conducts heat at an accelerated pace.
