Do We Need a Water Hardness Monitor to Monitor Soft Water Quality?

A water hardness monitor continuously compares your industrial or process water hardness to pre-set levels. If the water hardness exceeds those levels, the hardness monitors can trigger a water softener regeneration and/or an alarm or an alert. But do you need one for your industrial or commercial water softener system?

The answer may be “yes” because the cost/benefit profiles of water hardness monitors carry a strong ROI. If appropriately engineered, a water hardness monitor system can help you save money by reducing water wastage and minimizing conditioning agent use. To understand why, it’s helpful to understand the concept of industrial water softener hardness leakage.

During commercial or industrial water softening processes, calcium and magnesium ions are exchanged for sodium ions. As additional hard water is softened, the ion exchange limits may be exceeded with the result being hardness leakage. If an industrial water softener is not regenerated early enough in the process, there could be unacceptable levels of hardness leakage. This can be damaging to sensitive equipment in the short term and reduce the lifespan of all downstream equipment in the long term.

This is why a hardness analyzer that can monitor water hardness levels continuously (e.g. every two to 99 minutes) is so important. When the water hardness reaches a set level, regeneration can be automatically activated. In addition, alarms can be set to notify you when there is a very high level of hardness which may indicate bigger issues.

Some models can display current water hardness levels in ppm/mg/L as well as send a signal to your building management system (BMS) with those hardness levels, as well as alarms if preset levels are not met.

Put simply, water hardness monitoring increases the efficiency of the softener process because it recognizes whether regeneration is running correctly, and ensures that resin quality and regeneration conditioning agents are at appropriate levels. As a result, hardness monitors can pay for themselves very quickly.
