Dairy coolers

The characteristics of the process wastewaters from each pretreatment sub-group are shown in Table 3. Daily wastewater flows are characterized as intermittent because some major unit processes, e.g., cheese and butter making, are batch, and because milk processing equipment must be shut down daily for sanitizing to maintain rigid health standards. Relatively clean water may be a substantial portion of the total wastewater from a dairy plant. These waters are from condensers, refrigeration compressors, milk coolers, and air conditioning systems. 

D. aj-C,Hj-0 CH2-COOH. Umiled laboratory tests indicate that dilute aqueous solutions of 2. 4-D caused mild attack of 3003 alloy at ambient temperature. 2, 4-D has been handled in aluminum alloy sprayers and piping. CAUTION. See "Hak>-genated Hydrocarbons. Sec also Ref (3) p. 127. DAIRY PRODUCTS. Aluminum allays have been used for milk pails, milk cans, storage tanks, truck tankers, pasteurizers, coolers, butter chums aud tubs, foil hoods, and powdered milk driers. See also Ref (3) p. 204.
