Water treatment

Gypsum is used to regenerate and revive aquatic environments such as rivers, ponds, lakes and canals, or to condition and remineralise water in fish farms.

Gypsum can be used as a water treatment additive in many different areas and in different ways. It helps considerably to reduce the level of silt and mud build up by flocculating the clay present. 

It assists in clarifying the water and has the ability to neutralise the pH of acidic waters and so improve the development of aquatic life.

As calcium sulphate helps to maintain the equilibrium of calcium in the water, it provides an important means of support to fish. 


  • Superior solubility compering to alternative materials, which allows more rapid and efficient action and avoids the formation of chalky agglomerates.
