A button for providing a physical and sealing connection between a septum and an outlet stack of a water treatment cartridge having an opening. The button includes a first end, a second end opposite the first end, and a central portion which connects the first end to the second end. Located on the first end, there is a plurality of flexible locking members, configured for being inserted into the opening. To attach the button to the outlet stack, the locking members lockingly engage the outlet stack. The central portion has an annular groove provided with an O-ring. The O-ring facilitates a sealed connection between the button and the outlet stack. The button is connected to the septum by the use of either a washer and nonsolvent glue or heat staking.

A filtering system for water treatment including a head member having inlet and outlet ports and replaceable, disposable filter cartridge for insertion into the head member, the filter cartridge including a dual lug retaining system for retaining the filter cartridge in the head member, one of said lug retaining systems being disposed on the pressure vessel of the filter cartridge and the other of said lug retaining systems being disposed on the closure member of the filter cartridge.

Filter cartridge with a lugged concentric closure portion

A filtering system for water treatment including a head member having inlet and outlet ports and a replaceable, disposable filter cartridge for insertion into the head member, the filter cartridge including a dual lug retaining system for retaining the filter cartridge in the head member, one of said lug retaining systems being disposed on the pressure vessel of the filter cartridge and the other of said lug retaining systems being disposed on the closure member of the filter cartridge.

A water supply system for use in connection with a variety of water using equipment such, for example, as commercial ice makers and commercial steam cooking equipment wherein the water supply system utilizes a reverse osmosis unit thereby providing water of low mineral content to be used as product water in the equipment and at the same time utilizing the waste water generated from use of the reverse osmosis unit to provide cooling or condensing water for the same units to which the low mineral water is supplied.

Water supply system using reverse osmosis unit for treatment of water

An improved fluid dispensing system for use in dispensing beverages including unitary fluid filter cartridge adapted to be immersed in fluid to be dispensed, the fluid filter cartridge including a cannister having inlet and outlet openings in the lower end thereof, a filter septum in the filter cartridge connected to the outlet, adsorptive material disposed in the cartridge, a check valve controlled vent opening in the upper end of the cannister, and a riser stack connected to the check valve controlled vent opening.

Beverage dispensing system and filter cartridge therefor

A reverse osmosis sytsem for water treatment including a head member adapted to be fixedly mounted in a fliud supply line, an integral disposable reverse osmosis unit inserted into said head member, said osmosis unit including a pressure vessel, an end member attached to said pressure vessel and a reverse osmosis membrane module disposed in said pressure vessel and operatively associated with said end member.

Quick change reverse osmosis assembly

A chemical feeder device for treatment of influent liquid and designed for relatively free maintenance being free of moving parts and including a head member to be disposed in a liquid supply line, a vessel detachably connected to the head member and a disposable, replaceable chemical feeder cartridge also attached to the head member and disposed inside the vessel, the cartridge being a unitary structure including pre-inserted chemical material, built-in capillaries, an inlet check valve. The device is designed to feed a concentrated chemical solution into a stream of flowing liquid at a constant, very low resulting chemical concentration independent of liquid pressure, flow rate and interruptions in flow.
