Sodium hexametaphosphate (SHMP) is a salt of composition Na 6 [(PO 3) 6]. [3] Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates (empirical formula: NaPO 3 ), of which the hexamer is one, and is usually the compound referred to by this name.
Over the past couple of decades, a popular myth has circulated among swimming pool owners which claims that excessive accumulation of phosphates can feed algae blooms in pools, and that special “phosphate removers” are needed to prevent this from happening.
13 cze 2024 · Sodium hexametaphosphate, also known as (NaPO3)6, Calgon, or glassy sodium phosphate, is an inorganic compound with a unique chain-like structure of phosphate units. This structure gives SHMP its remarkable ability to bind to metal ions, a process called sequestration.
13 wrz 2022 · Sodium hexametaphosphate – This is added to pool water through tablets which slowly dissolve over time, gradually distributing the chemical throughout the entire body of water. This compound helps prevent the formation of calcium and magnesium scale deposits on pool surfaces which can often be a problem with pools that use high levels of ...
12 cze 2024 · Swimming Pool Water Treatment: SHMP is used in swimming pools to prevent calcium scaling, maintain water clarity, and enhance the effectiveness of chlorine-based sanitizers. It contributes to a clean and safe swimming environment.
Sodium hexametaphosphate is an effective sequestering agent, capable of binding to metal ions and preventing their interference with water treatment processes. It helps to inhibit scale formation and corrosion in water systems by sequestering calcium, magnesium, and other metal ions.
