Abstract:
An apparatus for dispersing additive into a fluid stream is disclosed. Also disclosed are systems comprising a fluid handling apparatus and an additive pod configured to disperse additive into a fluid stream. In some embodiments, the additive pods are easy to install into an outlet portion of a fluid handling apparatus, and do not require special training or the use of tools.
Abstract:
A water filter system includes a removable filter unit having a body portion including a proximal end and a distal end. The proximal end is adapted to be inserted into a filter head assembly. A laterally extending key member is disposed on the body portion and adapted to engage a key slot in the filter head assembly. An engagement protrusion extends from the proximal end. The engagement protrusion includes a first portion that has a first radius of curvature and a second portion opposing the first portion that includes a second radius of curvature that is larger than the first radius of curvature.
Abstract:
A water filter assembly is provided. The water assembly includes a cylindrical filter media, a pair of caps mounted at opposite ends of the cylindrical filter media, and a support column positioned within the cylindrical filter media. Inner and outer diameters of the cylindrical filter media can be selected in order to improve filtering of the cylindrical filter media. Also, at least one cap of the pair of caps can define an outlet having a diameter less than the inner diameter of the cylindrical filter media.

Abstract:
Technology is described for a water purification system. The water purification may include a carbon block. The water purification system may include an ion-exchange resin layer to reduce a pH level in water before neutral water passes into a fiber membrane filter. The water purification system may include the fiber membrane filter to receive the water from the carbon block and into a plurality of pores to remove suspended solids from the water.
Abstract:
Provided are electrochemical devices that are rechargeable, where the regeneration techniques are based on a batchwise 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 portable self-contained water treatment system. A raw water tank is provided which can be filled by a pump or by manually pouring dirty water into it. The raw water tank can also act as a chemical pre-treatment tank such that one or more pre-treatment chemicals can be added to the water contained therein.
Abstract:
A water filter communication system and method of using the system. A method of periodically reading water filter data associated with a water filter and retained by the water filter that has been positioned in an appliance includes the steps of: installing a water filter into an engaged position in a filter head assembly within an interior of a cabinet of an appliance that includes a water inlet and a water outlet and periodically, based upon and after a user's interaction with the appliance or the water filter, supplying power from the appliance to the filter read-write memory device engaged to the filter housing; transmitting water filter data to the appliance from the filter read-write memory device, which retains filter information.
Abstract:
A chemical release system. Implementations may utilize implementations of a first cartridge that include a body coupled with a cartridge head at a first end and coupled with an end plug at a second end where the cartridge head includes a through hole configured to engage with an annular flange in a main head. The body may have an internal cross section. The first cartridge may also include a flow restrictor plate disposed within the body between the first end and the second end where the flow restrictor plate is oriented substantially parallel to the cartridge head within the body, includes only one opening therethrough, and substantially conforms with the internal cross section of the body. The body may include one or more through holes in a side of the body located between the flow restrictor plate and the cartridge head.
Abstract:
An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface. The flapper valve also is provided with an actuating means to automatically open the flapper valve when the canister is mounted on the interface, which permits fluid to be drained from the canister when the fluid distribution system is being drained without disconnecting the canister from the interface.
