AQUASTILL is an autonomous evaporator operating without membrane, vacuum pump or compressor. This solution is easy to use, reliable and energy efficient. It can be adapted to solar (photovoltaic or thermal), geothermal or residual energy sources, in isolated or remote places under water stress. AQUASTILL can operate 24 hours a day, 7 days a week, with very little maintenance.


A new sea-water desalination technology.

AQUASTILL, developed by TMW, is a unique and patented seawater desalination technology inspired by the natural water cycle. It makes it easy to purify seawater or brine into pure, drinkable water.

AQUASTILL is particularly suitable for the treatment of highly charged or brackish water. AQUASTILL will treat brine (brine) from reverse osmosis treatment.

1Easy to use and ready to go
2Suitable for isolated and remote locations
3Can be used with any energy source – solar, geothermal, wasted heat and so on
4No membrane / Low Maintenance
5Fouling and scaling resistant
6Easy to clean and maintain
7Uses environmentally friendly pre-treatment materials
8Suitable for installations with a capacity of 1000 l/day up to industrial size
9Distant management and remote control


The Machine

AQUASTILL consists of an evaporation unit and a condenser, a fan to circulate air and an overheating mechanism for the liquid being purified. The assembly is then thermally insulated


The Technology

MHD technology is a unique process which has the following characteristics:

• Evaporation at atmospheric pressure and at a temperature of 85°C, the system is made entirely of plastics (PP, HDPE)
• Mean thermal output equal to 9 kW per treated cubic meter.
• Thermal power consumption between 70 and 150 kWh/m3
