Hard water in KwaZulu-Natal (KZN) can be addressed through several methods. Water softening systems, such as ion exchange units, can be installed in homes or municipal water supply systems to reduce mineral content. Additionally, the use of chelating agents in detergents can help mitigate the effects of hard water on laundry and appliances. Public awareness campaigns can also educate residents about the benefits of water treatment solutions and maintenance.

The decision problem that needs to be addressed in this situation is determining the best course of action or solution to a specific issue or challenge.
Hard water contains high concentrations of dissolved minerals, primarily calcium (Ca²⁺) and magnesium (Mg²⁺) ions, which can lead to scale buildup and reduce the effectiveness of soaps and detergents. To address this issue, water softening methods such as ion exchange or reverse osmosis are commonly used. In ion exchange, hard ions are replaced with sodium ions (Na⁺) using a resin, effectively reducing hardness. Alternatively, reverse osmosis filters out the minerals, producing softer water suitable for domestic use.

The Bohr model addressed the problem of decaying orbits of the electrons, which was a problem with the Rutherford planetary model. If electrons are located in discrete energy levels, their orbits do not decay, and the atom does not collapse in on itself.

Thesis
From what I have seen from commercials, it should fix the hard water problem especially if you use a well. They showed people putting salt into the hot water heaters.
