Protecting water reuse and pure-water systems #
This category covers equipment for industrial water reuse and pretreatment ahead of RO membranes, EDI, and ultra-pure water systems. Multi-stage filtration removes suspended solids, colloids, oils, organic matter, heavy metals, and microbial impurities, reducing the load on downstream equipment, extending service life, and improving water-quality stability.

Micro Screen Filter #
An internal-drum micro screen provides solid-liquid separation for finer suspended solids and is commonly used in water reuse and wastewater pretreatment. The official material lists it as part of the water reuse system.
Intelligent Differential Pressure Precision Filter #
This filter uses differential-pressure monitoring and automatic control for precision filtration, suitable for applications requiring stable effluent quality and automated operation. The official page positions it as a “super intelligent” precision differential-pressure filter.

Automatic Pressurized Sand Bed Filter #
A fully automatic pressurized sand bed filter removes suspended solids and fine particles. It can serve as pretreatment for purified water, pure water, or water reuse systems.
Automatic Pressurized Sand Bed Filter category
Automatic Continuous Flow Sand Bed Filter Equipment #
A continuous-flow sand bed design allows ongoing filtration and backwashing, suitable for larger flows or continuous operation.

System integration #
Yuan Chang’s water reuse solutions can be integrated with evaporation, membrane filtration, ion exchange, and UV disinfection units to form a one-stop system covering pretreatment, recovery, reuse, and discharge.
Water Reuse & Reclaimed Water Systems
Selection note #
Filtration equipment selection depends on raw-water quality, suspended-solids concentration, target effluent quality, treatment capacity, downstream membrane requirements, and backwash water volume. Final configuration and water-quality guarantees should be based on Yuan Chang’s engineering evaluation and, where necessary, on-site testing.
