Abstract
Disclosed is a dispenser 10 for a solid chemical 13 and a method of dispensing the chemical 13. Water enters via an inlet line 22 and is sprayed from a spray nozzle 21, so that the solid chemical 13 is dispensed in the form of an aqueous chemical solution via outlet line 17. The solution's concentration is adjustable by varying the distance between the spray nozzle 21 and the exposed dissolving surface of the chemical 13. The spray nozzle's position is adjusted by means of a screw jack 68, a push-pull cable 93, a solenoid 100, or a lever 117.
