Chemical properties and application background of magnesium sulfate monohydrate

Magnesium sulfate monohydrate, with the chemical formula MgSO ₄ ·H ₂ O, is a common inorganic compound. Its application in the field of water treatment mainly relies on its ability to increase water hardness and regulate water quality. Since it has adsorption and precipitation effects on various ions in water during the dissolution process, it is widely used in industrial and municipal water treatment systems.

Specific use of magnesium sulfate monohydrate

Use concentration

In water treatment, the concentration of magnesium sulfate monohydrate is usually between 50-200 mg/L, and the specific concentration is adjusted according to the water quality and treatment objectives.

Dosing method

Magnesium sulfate monohydrate can be added to water treatment by pre-dissolving solution. The specific addition methods include online addition and batch addition. Online addition is suitable for continuously running systems to ensure uniform distribution of the agent; batch addition is suitable for intermittently running systems.

Possible problems

Please pay attention to the following issues during use:

• Dissolution rate problem: Magnesium sulfate monohydrate dissolves slowly in cold water and requires sufficient stirring to ensure complete dissolution.
• Sedimentation problem: Excessive addition may lead to the formation of sediment and affect water quality.
• System compatibility: It is necessary to ensure compatibility with other treatment agents in the system to avoid chemical reactions.
