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.

  •  Workflow:

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.

  •  Workflow:

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.

  •  Workflow:

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.

  •  Workflow:

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.

  •  Workflow:

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.
