Application The reverse osmosis system REVOTEC produces demineralized water that is perfectly suited for manufacturing of beer and beer-based mixed drinks. Considering the quality of the raw water, the unit is designed individually for each specific application. Description Reverse osmosis (RO) is the reversal of natural osmosis. If a semipermeable membrane is placed between pure water and water with dissolved ions (salts) osmosis will come into play. The pores of the membrane only allow the passage of H2O, but not of salts, suspended solids, bacteria and larger molecules. Osmotic pressure due to a concentration difference on both sides of the membrane causes the pure water to pass through the membrane to dilute the solution on the impure side. This will continue until osmotic equilibrium (the same concentration on both sides)…
ApplicationThe ion exchange system IONTEC softens water used for beer and beer-based mixed drinks or for steam generation. Water hardness causes scale deposits in piping and process systems.DescriptionFor ion exchange there are ion exchange resins in the unit. These resins are insoluble granular polymers appropriate for the specific application. In their molecular structure they contain loosely held positive cations or negative anions. These ions exchange with the ions in the treated water as it passes through the unit.For softening of water a cation resin containing Na+ is applied. The calcium and magnesium ions which form hardness in water, creating scale deposits, are exchanged for the sodium ions of the resin. The resin binds more strongly with Ca2+ and Mg2+ than with Na+. When most of the ions in the resin have been replaced…
Raw water quality depends greatly on its source. Based on the raw water quality and the specifications for the purified water, Centec select the most appropriate technologies for each client. Usually, multi-stage regimes are necessary for water purification. For water pre-treatment, sand and multi media filters are used to remove suspended material (e. g. silt, clay, organic matter). Such material in water can reduce the effectiveness of downstream components such as ion exchange resins and reverse osmosis membranes. Soluble iron and manganese are found in water that contains no dissolved oxygen. They cause a metallic taste and form deposits in piping systems. The Centec De-Ironizer is designed for iron and manganese removal. If harmful bacteria and microbes are suspected, the water is disinfected by UV, ozone or free chlorine. Activated…
