My column name is "Varietes.rep" and I would like to precise that this variable is my individus, for my PCA. PCA can help you with this technology, both in design and construction of the installation.I'm steel a debutant on R and I would like to do an PCA. Both in terms of investment costs, operational costs and usage. Often a water softener is used as a pretreatment for a RO, but in this case the dosage of anti-scalant offers an interesting alternative. This brine is usually produced by dissolving salt tablets in water or can be supplied as a ready to use product by the chemical supplier. The advantage of this system is that the resins are used more optimally than in a duplex unit.įor the regeneration of the resins brine is used. It involves connecting three or more columns to one control unit with multiple columns in operation at all times. While one bottle is functioning, the other one is stand-by or regenerating.įor larger installations the principle of 'Merry go round’ is also used. A duplex installation consists of 2 bottles. When the installation is regenerating, no water can be softened. A simplex softener only consists of one softening column. These suspended particles could obstruct the water softener and prevent the resins from functioning correctly.Ī standard water softener can be provided in simplex or duplex configuration. It is important that the water to be treated by the water softener does not contain suspended particles. The harder the water, the more volume of resins needed to soften a certain volume of water. A softener is designed in function of the incoming water hardness and the capacity. A water softener is a type of ion exchanger where the Ca and Mg ions are exchanged, usually for sodium ions.
