Abstract: In one example, a liquid mixture nozzle for flowing a liquid mixture therethrough includes a body having a flow inlet and a flow outlet. The flow inlet is configured to couple to a first piece of piping and the flow outlet is configured to couple to a second piece of piping. The liquid mixture nozzle also includes a converging section having a decreasing diameter positioned adjacent the flow inlet, an orifice positioned at a narrow end of the converging section, an intermediate section having a constant diameter positioned adjacent the orifice, a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.

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.
