Abstract
An apparatus to dispense water soluble compositions into a process stream involves recirculating water through the water soluble chemical held in a tank. The recirculating water is heated to establish a defined temperature and repeatedly recirculated through the bed of chemical to achieve relative saturation concentration of the recirculating water. The water is dispensed from the recirculating unit thereby achieving a consistent concentration of chemical in the dispensed water.
