Chemical Dosing Control — Physical and Chemical Boundary Conditions

Conference paper


Dosing chemicals means starting the intended reaction. If, for instance, phosphate removing processes are aimed for, then the addition of reaction partners, usually in the form of metal salts leads immediately and spontaneously to the formation of (solid) metal phosphate.
