Chemical Dosing System
The chemical dosing system ensures the correct amount of process chemicals are delivered at the correct stage during
each operating cycle. Chemical addition is controlled by the automatic cycle controller and an alarm if the incorrect
amount of chemical is injected. The dosing system is designed for use with Malmet Chemical; other chemicals may impair
the operation of the system.
