Stackable cartridges for bulk feeders
A set of vertically stackable interacting cartridges for improving the delivery of biocide of a bulk feeder by positioning the stackable cartridges in a stacked condition within a chamber in the bulk feeder wherein the stackable cartridges are maintained in vertical interacting flow alignment with each other to provide enhanced control of the delivery of the biocide carried within each of the stackable cartridges without replacing the control valves of the bulk feeder.
1. The method of converting a bulk feeder having an inlet and an outlet to a cartridge system comprising:
placing a first stackable cartridge containing a first water treatment material therein with the first stackable cartridge having a bottom inlet and a top outlet in a lower portion of a chamber in the bulk feeder; and
stacking a second stackable cartridge containing a different water treatment material therein in the bulk feeder with the second stackable cartridge having a bottom inlet and an outlet with the first stackable cartridge and the second stackable cartridge each including a locater to maintain the top outlet of the first stackable cartridge and the bottom inlet of the second stackable cartridge in fluid alignment therebetween and in series with each other to direct a flow of fluid from a main line upward through the bottom inlet of the first cartridge, the water treatment material in the first cartridge and the outlet of the first cartridge and into the bottom inlet of the second stackable cartridge and the different water treatment material in the second stackable cartridge before discharging the water treatment material and the different water treatment material out of the outlet of the second stackable cartridge and into the main line.
2. The method of claim 1 wherein the first stackable cartridge is spaced from a bottom of the chamber of the bulk feeder to provide a flow chamber thereunder.
3. The method of claim 1 including the step of placing a batch of chlorine or bromine in the second stackable cartridge and a source of silver chloride in the first stackable cartridge.
4. The method of claim 1 including supporting the second cartridge on top of the first cartridge through a support on either said first cartridge or said second cartridge.
5. The method of claim 1 including adjusting a valve on the bulk feeder to maintain the chlorine at about 0.5 ppm or lower in the fluid when the first stackable cartridge and the second stackable cartridge are located in a stacked condition in the bulk feeder.
6. The method of claim 1 including the step of directing the water in the bulk feeder into the bottom inlet of the first stackable cartridge and back into the main line through an outlet located in a third stackable cartridge located in fluid communication with the second stackable cartridge.
