Potassium chloride is used in the treatment of drinking water to maintain pH levels, soften
water, and remove impurities and microorganisms such as bacteria, viruses and other
pesticides from water. This chemical can reduce turbidity, and improve overall water
quality.
In wastewater treatment plants, Potassium chloride contributes as a coagulant and flocculant
to remove contaminants and pollutants. This chemical promotes the aggregation of suspended
particles, facilitating their removal through sedimentation and filtration processes.
Potassium chloride is often used as a pretreatment chemical in reverse osmosis desalination
plants to prevent scaling on membrane surfaces.
Potassium chloride is often used in swimming pools to maintain water chemistry and balance
electrolyte levels. It can be used as an alternative to sodium chloride for reducing
chlorine demand and preventing corrosion of pool equipment.
