Seawater Treatment

VMSD (Vacuum Multi-Stage Desalination)

  • The most modern desalination technology based on vacuum distillation allows production of baby-suitable water

  • Capacity ranging from 5 to 1500m3 of fresh water/day

  • The biggest advantage is the possible usage of waste heat which allows to produce high-quality drinking water for close to ZERO running costs!

  • Environmentally Friendly

  • No CO2 Production

Extremely LOW-COST drinking water

Our technological design enables use of waste heat that is produced as a by-product in many production processes. This technology does not contribute to global warming.

Reduced pressure inside the device leads to a marked decrease in the water’s boiling point. This equals lower energy consumption and lower cost of drinkable or usable water produced.

Wasted heat saves money

VMSD is able to utilize for desalination process:

Conventional

(thermic, nuclear, hydro)

Alternative

(solar, wind, etc.)

The biggest advantage is the possible usage of waste heat which allows to produce high-quality drinking water for close to ZERO running cost.

Main disadvantages of Reverse Osmosis when compared with VMSD

  • VMSD produces 100 to 300 times cleaner water (in terms of depleted salts).
  • RO is more susceptible to cleanliness of the inlet water. Besides its own filter membrane it still needs pre-filtration and also uses activated charcoal which increases the running costs of the consumables.
  • RO is more limited by the salinity of the inlet water. If the salinity of raw water is increased also the pump capacity must be increased (need of installation of more powerful pumps).
  • RO is limited by inlet water temperature, its functionality is guaranteed only up to water temperature + 30°C.
  • RO manufacturers are unable to produce small units with capacity of only few m3/day.
  • RO has increased demands on time-out for filter regeneration (backflow of the filters) and the associated high consumption of purified water for self-regeneration and also for pressurized pump energy.
  • RO needs a qualified operator for its own operation, regular replacement of filter membranes and can be installed only in a clean operating environment.
  • RO needs chemicals (acids) for its washouts and these acids must be subsequently disposed.
  • If there is a waste heat source available on site RO has significantly higher running costs than the VMSD.

Water from VMSD can be used for irrigation

Fundamental difference is quality of output water.

The long-term use of water treated by RO for irrigation leads to gradual soil degradation due to the irreplaceable proportion of salt in irrigation water.

This can be illustrated by the case of Israel, where irreversible soil degradation has occurred in many places due to usage of low-salt irrigation water from Reverse Osmosis.

Technology of the 21st Century

  • VMSD is an innovative, next generation technology for desalination devices.
  • It is a unique method that allows for production of baby water from non-drinkable water.
  • It will enable the supply of water to regions affected by high amounts of diseases and high mortality rates caused by water pollution.
  • It can be used in areas with no infrastructure, using only solar energy.
  • It is energetically self-sustainable, using the waste heat from other equipment.
  • It does not require complicated technological and building preparations.
  • It has a long service life.
  • It does not require qualified personnel.
  • It can be widely used in agriculture: for irrigation, thickening of liquid fertilisers, etc.
  • It is effective in industrial use: i.e. when thickening or separating water from other substances.
  • It is suitable for water production on ships.
  • It brings immediate financial savings thanks to the use of waste heat.
  • It brings additional financial savings by not needing operating materials.
