Water & Wastewater Treatment
Water treatment is vital to the daily health and safety of every household. WANVALVE is determined to shoulder this social responsibility.
Project Success Stories
“Blue Oasis” Seawater Desalination & Storage
Location：Dubai, UAE
Challenge：Achieve 25-year maintenance-free operation in 48 °C, high-salinity seawater while treating 200,000 m³/day.
Solution：Electric Butterfly Valves
“Zero-Discharge” Industrial Wastewater Reuse
Location：Johor Petrochemical Park, Malaysia
Challenge：High-COD, high-solids wastewater had to be fully recycled; the system also demanded millisecond-level dosing control and emergency shut-off capability.
Solution：High-Pressure Solenoid Valves
Smart Waterworks Upgrade
Location：Yangtze River Delta, China
Challenge：Retrofit an aging plant without shutdown or pipe replacement, while enabling precise dosing and remote control.
Solution：Electric V-port Ball Valves
Municipal Effluent Equalization Basin
Location: Central Arizona, USA
Challenge: Daily 6 m level swing, 40 °C reclaimed water, requiring flow diversion every 2 h for 30 years without draining the basin.
Solution: Electric Actuator Pool Valves
Rhine River Intake
Location：Germany
Challenge：Unmanned pump station required DN300 valve to open/close within 5 s and <2 kPa pressure loss when fully open.
Solution：Full-Bore Electric Ball Valve, ISO 5211 F25 Mount
Atacama Brackish-Water Desalination
Location：Chile
Challenge：High-pressure pump discharge needed frequent start-stop (6×/shift); conventional gate valves caused water hammer.
Solution：Pneumatic Ball Valve, Double-Acting, Quick-Exhaust
