What is the maximum level of water hardness acceptable in treatment systems?

In water treatment systems, the maximum level of hardness acceptable is generally indicated by a threshold that ensures optimal performance of both the treatment equipment and the end-use applications. A level of 10 ppm of hardness is considered reasonable, as it minimizes scaling and deposits that can affect the efficiency and lifespan of plumbing and treatment systems. Hardness primarily stems from dissolved calcium and magnesium, and managing it is important to prevent issues such as clogging in pipes and reduced effectiveness of detergents.

Levels higher than 10 ppm can start to create problems with equipment and lead to decreased water quality, making 10 ppm a safe and effective upper limit for many water treatment systems. This balance allows for effective treatment without the negative impacts associated with higher hardness levels. Thus, selecting 10 ppm aligns with standard operational practices in the industry.
