Reverse osmosis is a proven, environmentally friendly and rational way to remove dissolved salts from natural waters. Desalination is carried out by purely physical means – no chemicals are required for the actual process.
Semi-permeable membranes are used in reverse osmosis. These membranes are permeable for water molecules, but not for the dissolved salts, organic matter, TOC (total organic carbon), bacteria and viruses contained in the water. When the pressure is increased, the water is forced through these membranes – and desalinated.
So much for theory. In practice, the quality of the components used and the durability of the membranes used, which have to withstand permanently high pressure loads, are decisive.
JUDO reverse osmosis units are preferably used in cases where demineralised water is required on an ongoing basis. The main fields of application: Steam boiler, cooling and air conditioning technology, beverage and food production, pharmaceutical and cosmetics industry, hospitals, brackish and seawater desalination.
We offer the optimally coordinated unit for every application – including the appropriate pre- and post-treatment. When it comes to membrane technology, we not only draw on decades of experience. We also cooperate with the world’s leading manufacturers.
JUDO reverse osmosis units are characterised by their compact design, low-noise operation, high-quality components, long service life and ease of maintenance. The microprocessor control enables simple and safe operation as well as economical operation.
Our units have proven themselves worldwide, even under difficult economic conditions. We supply both standardized and customized units in any size, also in container design on request.
Our project consultants are at your side with all their expertise and will be happy to advise you, from an initial offer to commissioning.
If a saline solution and pure water are separated by a semi-permeable membrane, the saline solution is diluted according to the natural law of osmosis by “sucking” in pure water which penetrates through the separating membrane. This process causes an increase in volume of the salt solution and thus a pressure difference between solution and water – commonly known as osmotic pressure. If a greater than osmotic pressure is artificially exerted on the salt solution, the process is reversed: Water is forced through the membrane in the opposite direction, leaving the dissolved parts behind.
