The ultimate TDS water tester can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million) before and after you use QuenchSea. Anything below 1,000 ppm is drinkable water. This TDS pen can test also seawater salinity levels.

A unique hydraulic system builds pressure to 60 bars (6,000 kPa) to remove salts from seawater through a reverse osmosis membrane.
QuenchSea has in-built ultrafiltration and microfiltration system to remove suspended solids, pathogens, parasites and microplastics.
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.
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.
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)

Seawater to fresh water instantly. The ultimate survival tool. QuenchSea can be a vital lifeline offering emergency access to clean water in the worst-case scenario. Only manual operation is needed to produce above 4 litres of fresh drinking water an hour




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
