Dry chemical dispensing system
First Claim
1. A system for dispensing one or more chemical solutions, comprising:
- a chemical dispenser having an internal cavity adapted to receive a chemical therein, and a fluid outlet port in fluid communication with the internal cavity;
a fluid supply conduit having a first end adapted to couple to a fluid source and a second end in fluid communication with the chemical dispenser internal cavity; and
a fluid pressure source in fluid communication with the fluid supply conduit, the fluid pressure operable to maintain a first substantially constant fluid pressure magnitude in at least a first section of the fluid supply conduit.

Abstract
A dry chemical dispensing system includes one or more chemical dispenser, a fluid supply conduit, and a fluid pressure source. The fluid supply conduit is adapted to couple to a fluid source, and supplies fluid from the source to dry chemicals installed in the chemical dispensers. The fluid supplied to the dry chemicals dissolves a portion into solution. The fluid pressure source maintains a substantially constant fluid pressure magnitude in the fluid supply conduit. Thus, any variations in pressure of the fluid source do not affect the pressure of the fluid supplied to the chemical dispensers. As a result, dissolved chemical concentration is substantially controlled.
