Water intake recommendation, desalination & remineralization solution, and water distribution pump station.
04
Plug & Play
Modular design: add 4 containers for another 5,000 m³/day of production.
05
Reliable, Long Service Life
30 years of experience in seawater desalination. Well-known brands; non-corrosive super duplex steel for pumps, energy recovery devices and high-pressure piping; UPVC/HDPE piping; heavy-duty marine paint on frame and containers. A durable UF membrane protects the RO high-pressure pumps, energy recovery devices and RO membranes, extending their life.
06
Low Energy, Easy Operation
High-efficiency low-pressure pumps (>80%), high-pressure pumps (>90%), energy recovery device (>95%) and low energy-consumption RO membrane (>5% lower). Upper computer control with cloud monitoring.

Desalination process

Based on UF and RO technology

1
Feed water
Other pretreatment such as DAF, clarifier or multi-media filter is available on request.
2
Ultrafiltration (UF)
Particles and bacteria are filtered out through the UF membrane. The filtrate enters the RO feed tank and is also used for backwashing the UF stack.
3
Reverse Osmosis (RO)
UF filtrate is pumped to the RO high-pressure pump. Fresh water is pressurized through the membrane to the RO product tank; concentrate is discharged after energy recovery. RO product water is also used for flushing the RO stack.
4
Remineralization
RO product water passes through a calcite filter, adding calcium and bicarbonate to meet drinking water standards.

Rated recovery rate is 42% for all models; rated product flow equals 58.3 / 116.7 / 175.0 / 233.3 L/s.
   1) The rated product flow and rated recovery rate are based on the design feed of 35,000 ppm and 20°C standard seawater. Contact us for higher product flow and higher recovery rate.
   2) The power consumption is based on the design feed of 35,000 ppm and 20°C standard seawater, but does not include the consumption by the intake pump and product distribution pump.
Water standards

Feed water and product water

Feed water standards
Salinity (TDS)³20,000 – 42,000 mg/L
Temperature5 – 35 °C
Turbidity⁴< 20 NTU
Chemical Oxygen Demand (COD)< 10 mg/L
Ferrous (Fe²⁺)< 0.1 mg/L
Manganese (Mn²⁺)< 0.1 mg/L
Oil and grease⁴0 mg/L
Product water standards⁵
Salinity (TDS)< 500 mg/L
pH6 – 8
Turbidity< 0.2 NTU
3) If feed water salinity is higher, the recovery rate might be lowered and a 2nd pass RO might be needed. Contact us for more details.
   4) If feed water turbidity or oil and grease is higher than the above specifications, QT will provide extra pretreatment. Contact us for more details.
   5) If the source water is natural seawater, the produced drinking water shall meet the WHO Guidelines for Drinking-water Quality, 4th edition, 2012.
