Successful case Turkey photovoltaic plant 100m³/h ultra pure water
system with UF+RO+EDI units
I. Overview
Ultra-pure water is the “invisible lifeblood” of efficient
photovoltaic cell production, with applications spanning the entire
process from silicon wafer cleaning to module encapsulation. The
ultra-pure water systems we provide to our Turkish photovoltaic
plant customers are highly efficient and energy-saving, serving as
a key technological foundation for enhancing cell efficiency
(>22%) and reducing the cost per kilowatt-hour.

IV. Application Advantages of Ultra-Pure Water Equipment
Economic Efficiency: EDI technology eliminates the need for
acid-base regeneration, reducing operating costs by 30%.
Concentrated water can be recycled to the front end of the RO
system (recovery rate: 50–70%).
Stability: Fully automatic control ensures water quality
fluctuations of ≤±0.1 MΩ·cm, avoiding production interruptions
caused by mixed-bed regeneration
Environmental Friendliness: No waste acid or alkali emissions,
compliant with EU environmental regulations (Turkey is currently
aligning with EU standards)
Scalability: Modular design (e.g., 100 tons/hour system) flexibly
adapts to production line expansion requirements

VI. Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea
water, etc)
Provide water analysis report(TDS , conductivity, or resistivity,
etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or
agriculture, etc )
