ABSTRACT
A clean-in-place (CIP) system circuit is designed, in simple terms, to clean all
process residues out of the equipment and piping included in the CIP circuit. With
the help of water prerinses, alkali wash, acid wash, and final water rinses, all at
controlled temperatures, the process residue is broken down and conducted to a
drain. As a CIP system designer, what happens to the CIP effluent after it leaves the
process area is not usually a concern. However, in most cases a waste treatment
system of some type and size will be required to treat the waste from the CIP as well
as the other building process effluents. CIP design decisions will have impacts
downstream on waste treatment requirements.
