摘要:
Eine Verwendung einer Salzsole (30) in einem Harzbehälter (4) für eine Wasserenthärtungsanlage (2), wobei der Harzbehälter (4) ein Ionenaustauscherharz (6) enthält, mit den Schritten a) Befüllen (216; 314) des Harzbehälters (4) mit der Salzsole (30), b) Ausspülen (208; 320) der Salzsole (30) aus dem Harzbehälter (4), ist dadurch gekennzeichnet, dass die Salzsole (30) zum Konservieren des lonenaustauscherharzes (6) zwischen den Schritten a) und b) verwendet wird, wobei zwischen den Schritten a) und b) der Harzbehälter (4) für eine Konservierzeit von wenigstens 8 Stunden mit der Salzsole (30) gefüllt bleibt (220; 336). Die Erfindung ermöglicht, das lonenaustauscherharz in einem Harzbehälter für eine Wasserenthärtungsanlage mit einfachen Mitteln zuverlässig und kostengünstig vor einer Verkeimung zu schützen.
摘要:
The system comprises: a first tank (24) for substances with water-softening properties, with an inlet opening (26) for water to be softened and an outlet opening (28) for softened water, a second tank (30) for salt, with a water inlet opening (32) and an outlet opening (34) for a regenerating brine formed following the dissolution of the salt in the water, - a line (36) connecting the second tank (30) to the first tank (34) for the outflow of the brine towards the first tank (24), a water supply line (10) having a branch-off point (18) into a first branch (20) supplying the first tank (24) and into a second branch (22) which leads to the inlet opening (32) of the second tank (30), - a first electric valve (12) control the flow of water through said supply line (10), a second electric valve (38) control a flow of water towards and through the second tank (30) for forming the brine, devices (14) for determining the amounts of water used for washing the dishes, forming the regenerating brine and washing the softening substances after a regenerating operation; an indicator (50) adapted to supply signals or data indicative of the hardness of the water used, and an electronic control unit (ECU). The control unit ECU is designed to control selectively, in predetermined ways, as a function of the hardness of the water, and through the electric valves (12, 38): * the quantity of water used for forming the brine used for each operation of regenerating the softening substances contained in the first tank (24), and * the frequency of the operations of regenerating and washing the softening substances.
摘要:
Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

摘要:
A hot-water supply system includes a switching valve (35) which has a bypass circuit which bypasses the water softening device (30) by directly connecting the water supply pipe (P1) and the inlet pipe (P3) of a hot-water supply device to each other, and a control unit (50). The control unit (50) includes a switching valve drive circuit which switches the switching valve (35) to the mode in which water is supplied from the water supply pipe (P1) to the hot-water supply device (I) via the bypass circuit, based on the determination of the timing of salt replenishment, and a display drive circuit which displays intention, in which salt replenishment is needed, on a display portion (51) of a remote controller (RC).
