Minn. R. 1540.0570 - REUSE OF WATER
Inspectors may permit the reuse of water in vapor lines leading from deodorizers used in the preparation of lard and similar edible products and in equipment used for the chilling of canned products after retorting, provided the reuse is for the identical original purpose and the following precautions are taken to protect the water that is reused:
A. All pipe lines, reservoirs, tanks, cooling
towers, and like equipment employed in handling the reused water are so
constructed and installed as to facilitate their cleaning inspection.
B. Complete draining and disposal of the
reused water, effective cleaning of the equipment, and renewal with fresh,
potable water is accomplished at such intervals as may be necessary to assure
an acceptable supply of water for the purpose intended.
C. Effective chlorination (not less than
approximately one part per million of residual chlorine at any point within the
cooling system) of the reused water utilized for cooling canned product is
maintained but with the understanding that chlorination alone is not to be
relied upon entirely or to be accepted in lieu of the requirements listed in
items A and B.
