Legionella Dominator™ Legionella Control Industrial Water Softener Calculator

Are Legionella or other harmful waterborne pathogens a concern in your organization? How do industrial water softeners play a role in bacterial growth? Water softeners are often breeding grounds for Legionella and other bacteria due to stagnant water in tanks and pipes exacerbated by often oversized equipment and warm environments. Eliminating softeners is not an option because unsoftened water helps harbor biofilm due to scale in the piping. The following calculations can be used as rough guides for our patent-pending Legionella Dominator™ Legionella control water softener system.

To help keep Legionella under control, start with a water management plan. Part of any water management plan or program is to reduce or eliminate hazards such as stagnant water and dead legs. You might be surprised to know that one hazard is an industrial water softener because it typically always has one tank sitting stagnant. The Legionella Control Softener System removes this hazard. Contact us for more information.

To size one of these systems, input the total flow, harness and peak flow. There are many variables beyond the scope of the Legionella Control water softener calculator such as water origin, changing demands and temperature, that are all variables that also have effects on water softener sizing and are not considered here. These guides are to be used for quick estimates only.

For detailed Legionella Control industrial water softener sizing including configurations (e.g. twin, triple, quad softeners) or pretreatment for reverse osmosis, deionization or other ultra high purity water treatment equipment, please email or call us at 888-416-8626. Our engineers are the same people you get in the field when there is an issue or when you call our free, unlimited technical support. Contact us now, and we’ll find the perfect system help you keep Legionella out of your building and work with you to form or assist in your water management plan.

Legionella Control Systems also offers preventative maintenance, engineering consultation, equipment leasing, financing, and build, own, operate options. Let us know if you would like information on how these services can help you reduce downtime and capital risks.

* 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).
