Hospital Legionella Control Water Softener Sizing Calculator & Guide

Are Legionella and other harmful organisms a concern in your organization? Are you meeting The Joint Commission Water Management Standard? Does the CMS Legionella standard apply to your facility? What are industrial water softeners’ roles in a hospital concerning harmful bacterial growth? Hospital water softeners are often breading grounds for Legionella, bacteria, and other pathogens due to stagnant water in pipes, valves and tanks. This is often exacerbated by often oversized equipment, impractical softener configurations and warm environments. Getting rid of softeners is not an option because removal of softeners results in scale, which helps harbor biofilm that protects Legionella. The calculations below can be used as guides for our patent-pending Hospital Legionella Control Softener System.

The most important step to keep Legionella under control is to have a Water Management Plan in place. Every effective water management program has a goal to reduce or eliminate hazards such as stagnant water and dead legs. A water softener is one of those hazards as it typically always has at least one or more tanks sitting stagnant. Our Hospital Legionella Control Softener System removes these hazards. To size one of these systems, input the total flow, hardness and peak flow. These guides are to be used for quick estimates only.

Legionella Control Systems also offers training, preventative maintenance, engineering consultation, equipment rental, financing, and build, own, operate options. Let us know if you would like information on how these services can help you reduce Legionella risk in your hospital or healthcare organization.

* Peak Continuous GPM is not instantaneous peak flow rate. It represents a continuous high flow rate at peak times of the day (e.g. for 30 minutes or more).
** Instantaneous peak flow rate is the maximum GPM for a short time (e.g. 1-5 minute period).
