Calcium Carbonate (Water Treatment Grade)

Product Overview

Mineral supplement for pH adjustment and alkalinity control in water treatment.

Detailed Description

Calcium Carbonate supplier in Oman - Global Chemicals LLC provides high-purity calcium carbonate for water treatment, pH adjustment, and alkalinity control in Muscat, Sohar, Salalah. Our calcium carbonate is ideal for remineralization of RO water, pH buffering, and water softening applications. In water treatment, calcium carbonate serves a specialised and critical role in remineralising desalinated water — replacing the calcium and alkalinity stripped by the RO process to create stable, non-corrosive water for distribution. Oman's PAEW desalination plants at Ghubrah, Barka, and Sohar use calcite (calcium carbonate) contactors or lime/CO2 remineralisation to achieve the Langelier Saturation Index (LSI) required for potable water distribution. Global Chemicals LLC supplies high-purity calcium carbonate powder and pellets for water remineralisation contactors, pH correction in RO permeate, and alkalinity control in treated water. The product is also used in industrial water treatment for neutralising acidic effluent and in aquaculture to maintain optimal water pH for fish and shrimp farming across Oman.
