Describe the permutit process for softening of hard water. |
|
Answer» t is a modern TECHNIQUE used to soften the HARD water. “Hydrated sodium aluminium silicate” is called “permutit”. These “complex salts” are also known as “zeolites”.The water softening process is carried out in a high cylindrical VESSEL packed with gravel sand and permutit. Durable water is INTRODUCED via an inlet. Water reaches the bottom of the vessel. The separation of impurities is done by the gravel layer. It then comes in contact with permutit that replaces and ions with ions in tank water.Therefore, free and ions water are collected from outlet.The chemical reactions are as follows.Where, |
