This paper discusses a study of the total cost of pasteurization for various electric‐power rates, daily water usages, and heat exchangers, based on list price of equipment. Because assembly is a comparatively simple job, the cost was not included. Results of the study were promising and a unit was designed for treating enough water to meet the daily needs of a family of five based on a usage of 50 gpcd (250 gal per 12 hr). A larger unit (1,000 gal per 12 hr) was also designed. Objectives of the pilot plant study were: to confirm the effectiveness of the unit in killing bacteria; to measure the power consumption of the unit; to determine maintenance requirements and reliability of the equipment; and, to check the significance of scale or corrosion in reducing the operating efficiency or life of the equipment.
