Lime has numerous applications in the chemical industry thanks to its natural properties and competitive price. It's used in the production of chemicals that can use the calcium and/or hydroxide molecule. In addition to being incorporated into other chemicals, lime's pH control abilities are readily utilized. Typically, process waters in the chemical industry require treatment with lime to correct its pH and adjust mineral content. Quite often, acidic waste waters are treated with lime before recycling or release into the sewage system.
