How Quenchsea 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 Filtration Process

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.

Our Technology

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)

Seawater To Fresh Water

It Takes Two Clicks…

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
