ABSTRACT
This chapter focuses on type and quality of water used in dairy for different purposes: Boilers, electricity and refrigeration system. Water is used in many processes in dairy industry such as cleaning, c ling, pretreatment, and rinsing of equipment or for recombination purpose. The quality of the water depends on its final use. In dairy, water is used in many forms: RO water, demineralized water for direct contact of product and soft water or raw water for cleaning purpose. The basic important utilities required for a dairy plant are as under: Water, steam, refrigeration, electricity, and air. When the product flow chart has been planned and checked, the approximate requirements for water, steam, refrigeration, electricity, air and other services can be calculated. Steam systems are part of almost every major industrial process today. The steam, in turn, is used to heat processes, to concentrate and distil liquids, or is used directly as a feedstock.
