Water purifying and vending apparatus
TLDR
A water purification system for a conventional supply of tap water and dispensing a predetermined quantity of processed water into a user-supplied container in response to the deposit of a predetermined value of specie, coin, or token as mentioned in this paper.Abstract:
A water purification system for purifying water from a conventional supply of tap water and dispensing a predetermined quantity of processed water into a user-supplied container in response to the deposit of a predetermined value of specie, coin, or token. The system includes a first purified water path and a second drinking water path. The first purified water path includes a reverse osmosis filter, a tank, and an afterfilter coupled between a prefilter and an ultraviolet disinfecting apparatus. The second path is substantially in parallel with the first path and includes a polishing filter. Manually operated switches can be used to select either drinking water of purified water and timing means are provided to insure that a predetermined quantity of water is supplied from the dispensing means into the user-supplied container. Valves are used to operate the first path for purified water, and the second path for a limited time followed by the first path for a longer time for better tasting drinking water. The system also includes a detector for sensing improperly processed water from the reverse osmosis filter and a diverter for sending improperly processed water to a sump. The ultraviolet disinfecting system or apparatus includes a hollow plastic housing with a lamp mounted therein. The lamp is wrapped in plastic and an annular space between the outer surface of the lamp and the inner surface of the housing provides a flow path for the purified water during which time disinfecting takes place prior to dispensing.read more

Water vending system
TL;DR: In this paper, the authors proposed a water vending system for the automatic dispensing of purified water from a machine which is preferably activated by coin or other form of payment. But the system is designed to reduce the frequency of servicing and the life of components without decreasing the quality of the vended water.
