Disclosed is a filter and a filter case using CDI, and a water purifier and a water softener using the filter case. Specifically, the filter case comprises: a case having a cylindrical shape and including a receiving space formed therein; a first cover having an inlet formed in the center thereof and configured to close one side of the case; and a second cover having an outlet formed in the center thereof and configured to close the other side of the case.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A monitored inline hard water processing assembly for conditioning hard water includes a cannister, which is cathodic, a disc, and a rod, which is anodic. The disc is removably couplable to a top of the cannister. The disc has a pair of channels positioned therethrough, each of which is in fluidic communication with an interior space defined by the cannister. The rod is removably couplable to the disc so that the rod is electrically insulated from the disc and extends into the interior space. A monitoring unit, which is electrically coupled to the cannister and the rod, is operationally couplable to a source of electrical current to provide a flow of direct current through the rod, the cannister, and water flowing therethrough. The monitoring unit comprises an indicator, which can indicate at least two resistance states of the rod.

A salt-level sensor for a water softener salt reservoir (aka brine tank) may comprise a laser distance detector or ultrasonic distance detector, a processor, a wi-fi module, a power module, a memory module, a housing, and a mounting assembly. The salt-level sensor may be configured to be mounted to the underside of the lid of a salt reservoir, with the distance detector directed away from the lid location. The mounting assembly may comprise one or more threaded elements and complementary nut(s), and may additionally comprise an orientation adjustment mechanism.

A method for measuring the salt level in a salt reservoir may comprise installing the salt-level sensor on the underside of the lid; emitting a signal toward to salt; receiving a return signal; and, based on the time between emitting and receiving the signal, determining a distance to the salt.

A portable water conditioning system is provided that includes a water conditioner, a first sensor, a second sensor, and a controller. The water conditioner has a plurality of conditioning stages that condition water. The plurality of conditioning stages include, in a direction of flow of the water through the water conditioner, a reverse osmosis stage and a deionizing stage. The first sensor detects a first condition of the water before the reverse osmosis stage. The second sensor detects a second condition of the water after the reverse osmosis stage. The controller is in communication with the first and second sensors and determines a health status of the reverse osmosis stage based the first and second conditions. The first and second conditions each include a level of total dissolved solids of the water.
