Tank assembly and method for water treatment
First Claim
1. A tank assembly for use in water treatment comprising:
- a tank having a molded liner of unitary construction with an integrally formed tank flange defining an opening and a surface generally co-planar with said opening, and an outer filament wound shell on said liner;
a head having a generally cylindrical neck with an end and a neck flange extending from said neck at a position axially distant from said neck end;
said neck being adapted for insertion into said tank opening and said neck flange and said integral tank flange being adapted for mutual attachment;
said head being adapted to receive and introduce untreated water into said tank and discharge treated water from said tank through an opening in said neck end;
a generally cylindrical clamp assembly having extensions for engaging said tank flange and said neck flange whereby said head is removably secured to said liner; and
a seal disposed between said head and said liner.

Abstract
The present invention involves a pressurized water treatment system and method having a unitary liner and flange and a plurality of interchangeable heads. The system utilizes non-threaded connections where periodic detachment is desirable to eliminate the cross-threading problems posed by plastic threads. The coupling devices include an improved clamp assembly to removably secure the water treatment heads to the liner flange or other system components and an improved spring clip to removably attach inlet and outlet lines to water treatment heads and fittings. By including L-shaped tabs, the spring clip reduces the chance of inadvertent dislodgement. The use of common connectors allows any of the interchangeable heads to be used with the liner and other fittings. Adapters can also be used to allow non-system components to be integrated into the system. A fill port adaptor can also be disposed between the liner and water treatment head to provide access to the tank interior without the removal of the head.
