Description: Potassium Monopersulfate (Potassium Peroxymonosulfate) Compound is not a mixture of 2KHSO5, KHSO4, K2SO4, but a pure chemical Compound. It is some kind of danger cargo in transportation in some countries. While still the normal chemical cargo in most countries.
Potassium peroxymonosulfate (Potassium Monopersulfate, 2KHSO5 KHSO4 K2SO4, 2KHSO5·KHSO4·K2SO4, Potassium hydrogen monopersulfate) is the potassium salt of peroxymonosulfuric acid.
The triple salt 2KHSO5·KHSO4·K2SO4 (known by the tradename Oxone) is a form with higher stability.

Application
Potassium Monopersulfate (Potassium Peroxymonosulfate) Compound will purify the water and kill some bacterial in the water. It is widely used in fish or shrimp rivers, swimming pools, and even clean our mouth.
Potassium peroxymonosulfate (Potassium Monopersulfate, 2KHSO5 KHSO4 K2SO4, 2KHSO5·KHSO4·K2SO4, Potassium hydrogen monopersulfate) is widely used in swimming pools to keep the water clear, thus allowing chlorine in pools to work to sanitize the water rather than clarify the water, resulting in less chlorine needed to keep pools clean. This is the main mechanism of action of Potassium peroxymonosulfate (Potassium Monopersulfate, 2KHSO5 KHSO4 K2SO4, 2KHSO5·KHSO4·K2SO4, Potassium hydrogen monopersulfate). There is also a unwanted effect of using Potassium Monopersulfate (Potassium Peroxymonosulfate) Compound in pools: it can lead to the common DPD #3 water test for combined chlorine to read incorrectly high.
25kg net plastic woven or paper bag with PE liner or 500Kg net jumbo bag, also can be custimized.
