Objective: To discuss the fundamentals of steam sterilization and the technical resources that can be used for a reduction of water consumption
in the sterilization process. Method: Review of literature and technical and international standards related to the principles of construction, operation,
and use of sterilization equipment by saturated steam under pressure. Results: The reduction in water consumption can be obtained by preferential
acquisition of equipment with free water pumps, shutdown of the source of steam-generating power when the equipment is not in use, use of equipment
with built-in degassers, assembly of the load in a way to facilitate vapor penetration and reduction of drying time, re-adjustment of the depth of
the vacuum to the low time of use of the vacuum pump, and the preventive maintenance of the steam line traps. In addition, a pretreatment system can
reduce the waste from reverse osmosis water treatment systems for steam generation. Conclusion: Knowledge of the fundamentals of sterilization by
saturated steam under pressure allows an implementation of measures for a reduction of water consumption in the sterilization process.
