How Quenchsea Works
The Ideal Emergency device. Seawater to freshwater.
QuenchSea is an innovative technology that combines a hydraulic system, triple pre-filtration and a small reverse osmosis membrane to desalinate seawater into freshwater using manual human power. At sea or on the coast, convert seawater into clean fresh drinking water instantly
How it works
Hydraulic
System
A unique hydraulic system builds pressure to 60 bars (6,000 kPa) to remove salts from seawater through a reverse osmosis membrane.
Triple
Prefiltration
QuenchSea has in-built ultrafiltration and microfiltration system to remove suspended solids, pathogens, parasites and microplastics.
Advanced Reverse
Osmosis Membrane
QuenchSea uses an advanced and state-of-the-art industrial Reverse Osmosis membrane. Seawater is demineralised under 55 bar to 60 bar (6000 kPa) pressure through a semipermeable membrane
Human
Power
QuenchSea is human powered, requiring no outside energy source. A simple detachable lever is used to pump seawater through a hydraulic system to create the required pressure.
More On How It Works
Reverse Osmosis
QuenchSea uses an advanced and state-of-the-art industrial Reverse Osmosis membrane to remove salts, bacteria, parasites and microplastics. Seawater molecules are forced through semi-permeable membranes to filter out impurities, salts and all contaminants leaving only pure safe drinking water that is guaranteed to be below 1,000 TDS (Total Dissolved Solids)
How to use
FAQs
Does QuenchSea need a battery?
No, the energy is generated using a sophisticated hand-operated lever and hydraulic system.
How long will the QuenchSea unit last?
The RO membranes will need replacing depending on usage. With good quality seawater and good maintenance the RO membrane will last between 6 to 12 months and produce up to 1,000 litres of fresh water
What are Reverse Osmosis membranes?
Reverse Osmosis, commonly referred to as RO, is a process where water is demineralised under pressure through a semipermeable membrane. The pressure required to desalinate seawater to freshwater is around 60 bar (6,000 kPa). The Quench Sea device replicates this pressure through a unique hydraulic system. During the Reverse osmosis process, the reject brine is ejected from the device via an outflow tube.
How do you maintain the QuenchSea unit?
Reverse Osmosis membranes are very sensitive to the quality of feed seawater. The QuenchSea already has a prefilter system but clear seawater should be used to help prolong the life of the membrane. Rinsing with fresh water after use will help with prolonging the life of the membranes.
Does the QuenchSea have a pre-filtration system?
Yes. QuenchSea has a unique triple pre-filtration system. One is a filter cartridge, the second is an ultrafiltration system.
How many Litres/Gallons can QuenchSea produce?
In ideal conditions, QuenchSea can produce up to 6 litres/1.6 Gallons of freshwater per hour
Can you use QuenchSea for freshwater water filtration?
No. QuenchSea can only be used for seawater
