Seawater To Fresh Water
QuenchSea 3.0 is a groundbreaking, low cost, portable, manually powered device that instantly turns seawater into drinkable freshwater.
Includes QS RO Membrane and Pre-filter
Advanced Reverse Osmosis Membrane. Seawater only. Capacity 8 Litres/2 Gallons per hour. You will receive 2 x QuenchSea RO Membranes SW1708
Please note these RO membranes only work with QuenchSea version 3.0
Ultrafiltration 0.01 Micron Hollow Fiber and microfiltration pre-filter to remove suspended solids, pathogens, parasites and microplastics. Antibacterial activated carbon fiber filter ensures that the taste of water is palatable and the odour of water is pleasant. You will receive 2 x QuenchSea Pre-filters
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.
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.
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
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.
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.
Yes. QuenchSea has a unique triple pre-filtration system. One is a filter cartridge, the second is an ultrafiltration system.
In ideal conditions, QuenchSea can produce up to 6 litres/1.6 Gallons of freshwater per hour
No. QuenchSea can only be used for seawater
