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.
