Abstract
Official abstract text for this publication.
A system, a cartridge and a dispensing valve for eliminating a drift or sag in BCDMH output from an inline dispensing valve containing a dispensing cartridge mountable within the inline dispensing valve with the dispensing cartridge containing a batch of water erodible cluster inhibiting BCDMH particles to provide a linear output flow of BCDMH which is responsive to flow of water though a cartridge in the dispensing valve and a method of obtaining a linear output in a dispensing system by increasing the size of particles in a dispensing cartridge in the system.
First claim
Opening claim text (preview).
We claim: 1. A BCDMH gravity feed water purification cartridge having a linear output in response to an increasing water flow therethrough with the gravity feed water purification cartridge having an antimicrobial chamber with a closed top comprising: a bottom water inlet in the BCDMH gravity feed water purification cartridge for directing a main stream of cooling system water upward into a bottom portion of the antimicrobial chamber in the water purification cartridge; a portion of a batch of granular flowable cluster inhibiting BCDMH particles located in the bottom portion of the antimicrobial chamber and a further portion of the batch of granular flowable cluster inhibiting BCDMH particles located in a top portion of the antimicrobial chamber wherein less than 8% of the granular flowable cluster inhibiting BCDMH particles will pass through a 20-mesh screen with the batch of granular flowable cluster inhibiting BCDMH particles in the top portion of the antimicrobial chamber flowable from the top portion of the antimicrobial chamber to the bottom portion of the antimicrobial chamber as the main stream of cooling system water flows through the bottom portion of the antimicrobial chamber and the granular flowable cluster inhibiting BCDMH particles located therein; and a bottom water outlet in the gravity feed water purification cartridge for directing the main stream of cooling system water out of the antimicrobial chamber and away from the gravity feed water purification cartridge wherein an amount of BCDMH in the main stream of cooling system water flowing out of the BCDMH gravity feed water purification cartridge is a linear function of the main cooling system water flow rate through the gravity feed water purification cartridge. 2. The BCDMH gravity feed water purification cartridge of claim 1 wherein at least 95 percent of the particles in the granular flowable cluster inhibiting BCDMH particles would pass through a ½ mesh screen. 3. The BCDMH gravity feed water purification cartridge of claim 1 wherein at least 93.72 percent by weight of the particles in the batch of granular flowable cluster inhibiting BCDMH particles are sufficiently large so as not to pass through a 20 mesh screen. 4. The BCDMH gravity feed water purification cartridge of claim 1 wherein the antimicrobial chamber has an internal diverging sidewall that diverges from the top portion of the antimicrobial chamber to the bottom portion of the antimicrobial chamber. 5. The BCDMH gravity feed water purification cartridge of claim 1 wherein an output rate of BCDMH from the antimicrobial chamber varies from 0 to 2 pounds per day in response to changes in water flow through the water purification cartridge.
