Section VII-2117 - Reclaimed WaterdpA. Condensing water for dairy product evaporators, and water used to produce vacuum or to condense vapors in vacuum heat processing equipment, shall be from a source complying with §925. B.1 of this Part. Provided, that when approved by the state health officer, water from sources not complying with §925. B.1 of this Part may be used when the condenser or vacuum heat equipment is constructed and operated to preclude contamination of such equipment, or its contents, by condensing water or by water used to produce vacuum. Means of preventing such contamination include: 1. use of a surface type condenser in which the condensing water is physically separated from the vapors and condensate; or2. use of reliable safeguards to prevent the overflow of condensing water from the condenser into the evaporator. Such safeguards include a barometric leg extending at least 35 feet vertically from the invert of the outgoing condensing water line to the free level at which the leg discharges, and/or a safety shutoff valve, located on the water feed line to the condenser, automatically actuated by a control which will shutoff the in-flowing water when the water level rises above a predetermined point in the condenser. This valve may be actuated by water, air or electricity, and shall be designed so that failure of the primary motivating power will automatically stop the flow of water into the condenser.

B. Condensing water for dairy product evaporators complying with this Section and water reclaimed from milk or dairy products may be reused when all necessary means of protection are afforded and it complies with the procedures outlined in this Part and the PMO.C. Reclaimed waterdp shall comply with the following requirements: 1. Reclaimed waterdp shall comply with the bacteriological standards of Appendix G, Section I of the PMO.2. Samples of reclaimed waterdp shall be collected daily for two weeks following initial approval of the installation and semi-annually thereafter, provided, that daily tests shall be conducted for one week following any repairs or alterations to the system.3. The organic content of reclaimed waterdp shall be less than 12.0 milligrams per liter as measured by the chemical oxygen demand or permanganate consumed test; or a standard turbidity of less than 5.0 units.4. Automatic fail-safe monitoring devices shall be used to monitor and automatically divert to the sewer any reclaimed waterdp which exceeds the standards.5. The reclaimed waterdp shall be of satisfactory organoleptic quality and shall have no off-flavors, odors or slime formations.6. The reclaimed waterdp shall be sampled and tested organoleptically at weekly intervals.7. Approved chemicals, such as chlorine, with suitable detention period may be used to suppress the development of bacterial growth and prevent the development of tastes and odors in reclaimed waterdp.8. The addition of approved chemicals shall be by an automatic proportioning device prior to the reclaimed waterdp entering the storage tank to assure satisfactory quality reclaimed waterdp in the storage tank at all times.9. When chemicals are added, a daily testing program for such added chemicals shall be in effect and shall not add substances that will prove deleterious to use of the reclaimed waterdp or contribute to product contamination.10. The storage vessel shall be properly constructed of such material that it will not contaminate the reclaimed waterdp and can be satisfactory cleaned.11. The distribution system within a plant for such reclaimed waterdp shall be a separate system with no cross-connections to a municipal or private water system or any other potable water distribution system.12. All physical, chemical, radiological and microbiological tests on the reclaimed waterdp shall be conducted in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater.D. When §2117. C.1 through §2117. C 12 of this Section are satisfied and documented, reclaimed waterdp may be used for the following limited applications:1. pre-rinsing of the product contact surfaces where pre-rinses will not be used in food products; and,2. cleaning solution make-up water; provided that for either of these uses, the following additional items are complied with: a. there is no carry-over of reclaimed waterdp from one day to the next, and any reclaimed waterdp collected is used promptly or the temperature of all reclaimed waterdp in the storage and distribution system is maintained at 63E C (145E F) or higher by automatic means; or, the reclaimed waterdp is treated with a suitable, approved chemical to suppress bacterial propagation by means of an automatic proportioning device, prior to the reclaimed waterdp entering the storage tank;b. distribution lines and hose stations are clearly identified in accordance with LAC 51:XIV.607 as limited use reclaimed waterdp;c. water handling practices and guidelines are clearly described and prominently displayed at appropriate locations within the plant; andd. these water lines are not permanently connected to product vessels, without a break to the atmosphere and sufficient automatic controls, to prevent the inadvertent addition of this water to product streams.E. Reclaimed waterdp may be used as boiler feed-water for boilers which are not used for generating culinary steam, or in a thick, double walled, enclosed heat exchanger.La. Admin.
