ABSTRACT:
This specification discloses a system and method for blending a dry chemical and a liquid. The system is comprised of a hopper for receiving and feeding the dry chemical into a pipe where it is transported by gas to a liquid weir and there mixed with the liquid. The hopper is adapted for having a positive pneumatic pressure applied at an upper location thereof and a negative pneumatic pressure applied at a lower location thereof to feed the dry chemical into a pipe. The dry chemical is then transported by gas through the pipe and directed from the downstream end of the pipe into the liquid weir. The liquid weir is adapted for having liquid flowed therethrough to mix and blend the liquid with the dry chemical. A container is provided to contain the blended mixture.
