Introduction to Softener Efficiency
Brine efficiency is defined by the number of grains of recoverable hardness removal capacity achieved by a softener per pound of salt used in regeneration. A perfect score is around 6,000 grains/lb. Softeners rated as ‘high efficiency’ by WQA run at 4,000 grains/lb., but most operate in the 2,500-grain range due to the inherent lower efficiency from the use of more salt than is needed for good results (see Figure 1). Counterflow regeneration of a softener saves salt and saves water. But that’s not the only thing green about it. It also saves customers money while actually improving performance. From the viewpoint of the manufacturer/dealer, there’s a lot of sizzle with the higher-tech approach to softening that will certainly offer numerous advantages to help improve sales.
