Desalination of brackish water 

up to 60,000 L/D with 70% recovery


  • Australian well water often contains high level of dissolved solids which make the water not suitable for agricultural applications. Mostly affected in a negative way is irrigation of fruits, vegetables, crops but also water for animal supply. High dissolved solids make no use of the water even though it is right there where it could be of a great benefit for farmers, growers, industries and homes.

  • Australian well water also contains high level of suspended solids which lower significantly the efficiency and life expectancy of traditional water treatment.

  • Usage of city water accounts for high operational cost. Proper and efficient water treatment for existing well water will lower significantly the operational cost of farmers and businesses where it needs to be applied.

  • Well water contains additionally high level of microbiological contamination, silt and organics which are completely and efficiently removed.



Together with the growing population on the planet, there is an increasing demand on water supplies. In some countries , there are already insufficient freshwater resources to supply residents, industry and agriculture. These areas are dependent primarily on the use of the salt water. Salty sea water contains large amounts of dissolved substances, reaching concentrations up to 37 000 mg/l and because of such a high concentrations, it is not suitable for further use. With the use of the membrane processes, it is possible to remove the solubles and enable its further use as a drinking water, in the industry, or in agriculture. The most suitable method to desalinate the sea water is the reverse osmosis, which provides a highest efficiency in relation to energy consumption.

There is a vast amount of water on the Planet, but only the less than one thousandth of a percent is fresh water in a liquid form. Almost 98 percent of water is in the oceans and the seas - the salt water. Because of its high level of dissolved solids, the sea water is quite unsuitable for consumption or for another, eg. industrial use.

If the water contains more than 2000 mg/l of dissolved solids, it is referred to as a salty water and therefore unsuitable for drinking. The average content of dissolved solids in the sea water ranges between 33 000 to 37 000 mg/l. If such a water has to be suitable for drinking, it would be necessary to decrease the dissolved solids content to less than 1000 mg/l (such water is already known as edible), or preferably to a value of about 500 mg/l.

There is a number of possibilities to reduce the amount of dissolved solids in the salt water. Decreasing of the dissolved salts content is generally called as desalination and the process mostly used for the salt water desalination is the membrane technology.
