ECOSTILL ™, developed by TMW is a unique and patented evaporative-concentration technology which was inspired by the natural water cycle Any amount of any polluted liquid can be recycled into purified water easily and at low cost.


ECOSTILL™ is a self contained evaporator operating without a membrane or a vacuum pump. This is easier to use, more reliable and lower cost than any other competing waste-water treatment technology. ECOSTILL™ can be used on any already existing industrial water system and can operate 24 hours a day, 7 days a week with very little maintenance.

A dedicated analysis is always performed


The machine

The ECOSTILL™ module consists of an evaporation unit and a condenser, a single fan to circulate air and an overheating mechanism for the liquid being treated. The assembly is then thermally insulated with expanded poly-propylene. It concentrates the waste while producing pure water. The liquid is concentrated as follows: when some of the water evaporates from the untreated effluent the pollutants such as metals, organic materials and so forth do not evaporate and are concentrated. The vapour condenses and produces pure water.

The Technology

MHD technology is a unique process with the following characteristics:

  • Evaporation at atmospheric pressure and low temperature (85°C)
  • The machine is entirely made in plastics (PP & HDPE).
  • Average power consumption between 6 kW (ECOSTILL™ 400) and 24 kW (ECOSTILL™ 1500).
  • Thermal power between 70 and 150 kWh/m3 of treated raw effluent.
  • Production of a re-useable distillate and concentrate ready for disposal.
  • Machine Size: from 4 m² (ECOSTILL™ 400) to 30 m² (ECOSTILL™ 3800) and 2.5 m high.
