The VERDA Utility Water Quality System:

A single point treatment for all Central Sterile Processing Utility Water is recommended to address issues with multiple point-of-use filters, current low hot water temperature, and the desire for functionality upgrades in the future. The proposed system is comprised of the following elements:

• Series sediment filtration o 5µm pleated polypropylene filter (98% retention of particles 5 microns and larger i.e., dirt, rust) o 0.5µm pleated polypropylene filter (98% retention of particles 0.5 microns and larger i.e., silt)

• Water softening o Softening of feed water for Utility Water heaters

• Utility Hot Water o Electric water heaters for hot Utility Water production

• Recirculation of hot Utility Water o Ensures consistent hot water temperatures are maintained at point-of-use faucets and SPD equipment (e.g., ultrasonic, washer-disinfectors) o Constant water flow to eliminate stagnant hot water in the Utility Water piping network, which is prone to bacteria growth, even though it is chlorinated

• Modular interconnected palletized systems o This design feature streamlines the integration, reducing both the installation time and on-site plumbing labor and materials costs o The modular design also allows for the integration of additional water treatments (e.g., pH balancing, TOC reduction) o In the future, the modular system, when additional water treatment options are desired, provides a lower cost initial set-up lower upgrade costs

• Predictive Maintenance and Monitoring System o Expandable, cloud-based monitoring system o Alarmed to alert via text or email
