This program facilitates the selection of a softener from the analytical hardness data, estimated consumption and average flow rate. It is also possible to select the device on the basis of the higher resin efficiency or with a reduced salt consumption. The hardness can be expressed in ºf, ºd, ºClark, gpg, mmol/L and mg/L CaCO3 The program provides information on: - Hardness to remove - Exchange capacity required per day - Liters of resin recommended - Water flow to soften - Blending flow to obtain the desired residual water hardness - Estimated cycle - Time between regenerations - Salt consumption per regeneration - Salt consumption per m³ - Salt consumption per month - Estimated consumption of water per regeneration - Increase of sodium concentration in the softened waterMore information about all these concepts can be found (in Spanish) in the web page: www.quimicadelagua.com
