Magnesium is a mineral found in a wide variety of foods. Inside of our bodies we mostly find magnesium in our bones (60-65%), in our muscles (25%) and in other cell types and body fluids. Magnesium cannot be made in our body like all minerals, which is why we need to take it in through magnesium-rich foods.
The Brinell hardness number (HB) is the load divided by the surface area of the indentation. The diameter of the impression is measured with a microscope with a superimposed scale. The Brinell Hardness Number is computed from the equation: P is the applied load of 3000, 1500, or 500kg.
Just as salt dose and brine concentration has an impact on a system efficiency, the rate at which brine is introduced will also have an impact. For a given salt dose and concentration, the brining rate will determine brine contact time with the resin. Increased contact time will increase the capacity and efficiency of the softener system; therefore, the slower brine can be introduced the better. There are practical limitations to how low the flow rate can go.
