Description
Technical Field
The application belongs to the technical field of water treatment, and particularly relates to a modular efficient water treatment system and a treatment method.
Background
Water from naturally occurring sources includes a variety of minerals and substances such as calcium carbonate and magnesium carbonate. The solubility of calcium carbonate in water decreases with increasing temperature, whereby when water is heated with a water heater or simply enters a warm building from a cold outdoor pipeline, the calcium carbonate crystallizes into "calcite" (also known as limestone). Calcite is dense and lumpy and can form hard scale by binding metals such as iron, magnesium and manganese into its crystal structure by deposition on other surfaces, for example, inside pipes and other plumbing, water heaters, shower heads, dishwashers and equipment transporting or using water. The inclusion of other metals often gives hard water scales an orange-brown color. Hard scales adhere strongly to surfaces and are difficult to remove. Hard scale deposition and accumulation can create a number of problems, including reduced service life of the water heater, leaks at the water supply connections, and restricted water flow, for example, by changing and narrowing the interior of the pipes and plugging water supply components, which in turn can affect the proper use of the water-using equipment.
