Abstract: A water-on-water filtration system that includes a filter member and two storage vessels. The system includes a plurality of valves that are controlled to place a first of the storage vessels in a fill state in which the first storage vessel is being filled with filtered water, and concurrently place the second of the storage vessels in a service state in which filtered water held in the second storage vessel is delivered as an output of the filtration system. The filtration system can be configured to supply a constant output of filtered water to meet a constant demand while using a relatively small filter member and relatively small storage vessels.

Abstract: Provided are electrochemical devices that are rechargeable, where the regeneration techniques are based on a batch-wise application of current or current density to the cells, where there are a service mode where no current or current density is applied and a recharge mode where a current or current density is applied. Electrochemical and EDI systems according to the embodiments herein are suitable for deionization and/or purification of typical municipal tap quality water in applications where demand for purified, low-TDS water is intermittent. Such operations avoid the use of chemical additions for regeneration purposes. In addition the cells provided herein are amenable to small footprints for consumer and commercial applications such as: dishwashers, washing machines, coffee and espresso makers, ice makers, steam tables, car wash water sources, and steamers.

Abstract: A filter unit that includes a slide assembly and a head assembly. The slide assembly is moveably mounted to the head assembly. The head assembly is configured to receive an end portion of a filter cartridge in releasable engagement. The slide assembly is movable between a first position in which the slide assembly prevents disengagement of the filter cartridge from the head assembly, and a second position in which the filter cartridge is permitted to disengage from the head assembly. In the second position, the slide assembly maintains engagement with the head assembly until an external force is applied by engagement of the filter cartridge with the slide assembly when removing the filter cartridge from the head assembly.
