Title: METHOD FOR OPERATING A WATER TREATMENT SYSTEM
Abstract:
The invention relates to a method for operating a water treatment system, with a first container (1A) and an additional container (1B, 1C), through each of which a respective partial volume flow (5A, 5A' 5A", 5A"', 5B, 5B', 5B", 5B'", 5C, 5C', 5C", 5C'") is caused to flow in parallel and each of which is equipped with a water treatment element that can be regenerated, wherein the method comprises the following repeating steps: • determining the remaining capacities (2A, 2B, 2B', 2B", 2B"', 2C, 2C', 2C", 2C'") of the water treatment element in the containers (1A, 1B, 1C) and the partial volume flows (5A, 5A' 5A", 5A"', 5B, 5B', 5B", 5B'", 5C, 5C', 5C", 5C'") through said containers,• determining a regeneration threshold value (RGW) for the first container (1A), wherein a regeneration process is initiated in the first container (1A) if the remaining capacity (2A) in the first container (1A) falls below the regeneration threshold value (RGW) and wherein the regeneration threshold value (RGW) is determined on the basis of the partial volume flows (5A, 5A' 5A", 5A"', 5B, 5B', 5B", 5B'", 5C, 5C', 5C", 5C'") and/or the remaining capacity (2B, 2B', 2B", 2B'", 2C, 2C', 2C", 2C"') of the water treatment element of the additional container (1B, 1C).
