Embodiment Construction

[0076] figure 1 An embodiment of a water softening device 1 according to the invention is shown in a schematic overview.

[0077] Raw water, ie unsoftened water, flows from a local water network, for example a drinking water network, to the water softening system via the inlet 2 for raw water. Raw water should be subjected to partial or complete softening.

[0078] Arranged at the inlet 2 is a pressure reducer 12 which regulates the water pressure in the subsequent water softening plant to a constant input pressure pe of eg pe=2 bar.

[0079] In softening operation, the raw water flows completely to the control head 9a with the valve 20 closed, which leads the raw water for complete softening through the softening device 4a, which here is formed with ion exchange Container 4 for resin 5. The softened water then flows to the outlet 3 for softened water. If only partial softening is desired, the raw water flow can be divided in the control head 9a into a subflow to be soften...

Abstract

The invention relates to a water softening device comprising: a softening unit, in particular comprising at least one container with ion exchange resin; a storage vessel used for storing a regenerantsolution and further comprising a solid regenerant salt; an ejector used for transporting the regenerant solution from the storage vessel to the softening unit; an electronic control device for controlling the delivery of the regenerant solution from the storage vessel into the softening unit. The water softening device is designed to: predetermine or measure the volume V1 or the mass M1 of the delivered regenerant solution in a delivery step; predetermine or measure a duration t1 for conveying the volume V1 or the mass M1; and the electronic control device is used for determining the concentration CRM1 of the delivered regenerant solution and / or a parameter dependent on the concentration of the delivered regenerant solution from V1 or M1 and / or t1 by means of a stored calibration function. The invention also relates to a method for operating the water softening device.

Description

technical field [0001] The present invention relates to a kind of water softening equipment, this water softening equipment comprises: [0002] a softening device comprising, inter alia, at least one container with an ion exchange resin, [0003] a storage vessel in which the rejuvenating agent solution is stored, in particular, solid regeneration salts are also contained in the storage vessel, [0004] An injector for conveying regenerant solution from the storage container to the softening device, an electronic control unit which is provided for controlling the delivery of regenerant solution from the storage container to the softening device during regeneration operation. Background technique [0005] Such a water softening device is known from DE 10 2010 028 756 A1. [0006] Water softening devices are used when softened water is desired or required for technical or comfort reasons. The softening device of a water softening plant is typically based on the principle of...
