ABSTRACT:
A feeder system comprising a hopper for holding dry chemical. A feed tube extends from the hopper and is for delivering dry chemical to a mixing tank. A first solenoid actuator is provided for controlling the opening and closing of a first solenoid actuated gate that is disposed in the feed tube. A second solenoid actuator is provided for controlling the opening and closing of a downstream second solenoid actuated gate disposed in the feed tube. A central controller is provided that is in communication with and controls the system components including the introduction of the dry chemical and process water into the mixing tank. The central controller controls a metering pump that pumps chemical mixed solution out of the mixing tank.
