Systems and methods for passively dosing fluid with a consumable additive in a controlled and measured fashion. A capsule containing the additive is placed in a fluid reservoir and passively doses static water in the reservoir over time. Instead of directly exposing the additive to the dispensing system's fluid, fluid within the capsule's internal volume becomes saturated with dissolved additive and then diffuses to the dispensing system's fluid through one or more openings. The one or more openings are sized so the that the diffusion occurs at a predetermined rate, and are positioned on the capsule to prevent an undesirable fluid exchange which extends the life of the additive and maintains a constant diffusion rate. The size of the cartridge can be selected to control the volume of fluid that is passively dosed within the reservoir, thereby controlling an overall concentration of additive in the total volume dispensed.

A sewage treatment chlorinator for use at a site not connected to a municipal sewer system and system and method for use of the same are disclosed. In one embodiment of the sewage treatment chlorinator, a housing includes an external conduit coupled in a t-connection to a flow tube. An inner canister is sized to be selectively inserted and removed from the external conduit and includes a perforated end cap having a flow deck sized to suspend a chlorine tablet within a contact chamber of the flow tube. The flow tube receives effluent form an aerobic tank and discharge treated effluent to a post-treatment tank. At least a portion of the discharge from the flow tube is gravity-based discharge into the post-treatment tank.

A system and method for delivering silver ion biocide is described herein. The systems described relate to passing water from a water system through a silver ion release module and optional high-concentration silver ion release module. The system includes an analyzer, detector, and/or controller for monitoring the concentration of silver ion and adjusting the flow path, flow rate, temperature and/or pH of the water in order to obtain the desired concentration of silver ion. The system optionally includes other metal ions released into a water system, the concentration of which may be used to automatically calibrate the described system and/or cause the system to take actions based on the measured concentration of silver ion or of the second metal ion.

A method for producing an ionized water product for coffee comprises the steps of introducing source water to an ionization system, passing the source water through one or more reaction vessels, wherein one or more ionic species are introduced into the source water, and combining products of one or more reaction vessels to produce the ionized water product having between about 10 ppm to about 40 ppm magnesium ions, about 10 ppm to about 40 ppm calcium ions, and about 40 ppm to about 90 ppm total of bicarbonate and carbonate ions.

A brine tank salt level detection apparatus is disclosed. The apparatus includes a housing secured to a lid of a brine tank, where the housing supports an infrared emitter and an infrared sensor. The apparatus is configured to emit an infrared signal, receive an infrared signal, and determine whether a salt level in the brine tank is below a predetermined level using, at least in part, the receipt of the infrared signal. A method for determining a salt level in a brine tank is also disclosed. The method can include emitting an outgoing infrared signal, receiving an incoming infrared signal, determining whether the salt level is below a predetermined level based at least in part on the receipt of the incoming infrared signal, and when the salt level is below a predetermined level, alerting a user of the low salt level in the brine tank.

The invention relates to a compressed salt block and a liquid treatment apparatus provided therein with at least one such compressed salt block. The liquid treatment apparatus comprises a housing adapted to accommodate at least one liquid treatment tank and at least one compressed salt block. The housing comprises a first space portion for accommodating the at least one liquid treatment tank, and a second space portion for accommodating at least partially the at least one compressed salt block; wherein the at least one compressed salt block comprises an extension portion which extends into a space in the first space portion between an external surface of the at least one liquid treatment tank and an inner wall surface of the housing adjacent the external surface of the at least one liquid treatment tank to thereby position the at least one compressed salt block within the housing. The compressed salt block comprises an elongated body having an irregular cross section, the cross section comprising a base side and a functional side opposing the base side, wherein at least a portion of the functional side forms an acute angle to the base side thereby forming the extension portion of the salt block.

The invention is an apparatus for preparing a chemical solution. A device of the present invention includes a housing including a lower chamber and an upper chamber and a dissolving bowl arranged at an interface of the lower chamber and upper chamber. The dissolving bowl includes a grid disposed within. Solid, undissolved chemical material rests on a top surface of the grid, such that the grid is able to maintain physical separation of the solid, undissolved chemical material from at least a bottom portion of the dissolving bowl. The device further includes a nozzle disposed within the dissolving bowl and positioned so as to direct flow of aqueous fluid into the dissolving bowl and towards the grid. The dissolving bowl further includes an outlet in fluid communication with the lower chamber to thereby allow for a prepared chemical solution to flow from the dissolving bowl into the lower chamber.

The present invention relates to a system for dissolving at least one detergent tablet or detergent granulate in water and thereby creating a detergent liquid, said system comprising a chamber (103) for dissolving said tablets or granulate, wherein said chamber comprises an opening (105) for receiving said detergent tablet and said water and a detergent liquid outlet (135, 137). The chamber further comprises an inner colander (125) for positioning said at least one tablet or detergent granulate. Thereby, a very efficient dissolving process can be performed, and a uniform detergent liquid is obtained. By positioning the tablets or granulate inside the colander, it is ensured that all sides of the tablet are in contact with the liquid in the chamber.

A method of treating water includes directing a stream of water towards a lateral side of a water treatment substance body contained within a holder. The water stream serves to abrade the water treatment substance body, thereby to dose the water with the water treatment substance. Dosed water is thus formed. The dosed water is allowed to pass through at least one opening in the holder.

A string of reactant chambers configured for inserting a reactant into each reactant chamber, in the string of reactant chambers, while maintaining the reactant chamber being filled in the string of reactant chambers is provided. The string of reactant chambers has a first reactant chamber, a second reactant chamber, and a system configured to maintain the reactant chamber being filled in the string of reactant chambers. The system has a first removable end cap on each reactant chamber and a coupler on each reactant chamber configured for the removal of the first removable end cap and maintaining the reactant chamber in the string of reactant chambers. A process for charging a reactant chamber is also presently disclosed.
