Lime in drinking and process water

Lime in Water treatment In both drinking and process water preparation, lime is mainly used for pH adjustment and/or water purification. Lime milk is a cost-effective reagent which reduces the water's hardness by precipitating the bicarbonates dissolved in it, thus preventing the formation of scale. In Germany, the Lhoist Group has a separate company, Akdolit, that produces and distributes a wide array of products for the preparation of drinking and process water. In waste water treatment plants (both urban or industrial), lime is widely used for correcting the pH balance of acidic waters, for precipitating heavy metals and phosphates, and for its flocculating action. <a href="../Frame_Drinking_water/Frame_Drinking_water.htm">Drinking water treatment</a> <a href="../Frame_ProcWater/Frame_ProcWater.htm">Process water treatment</a> <a href="../Frame_Waste_Water/Frame_Waste_Water.htm">Waste water treatment</a>
