Lime

Lime is a versatile chemical widely used in wastewater treatment for pH adjustment, alkalinity control, and the removal of dissolved contaminants. It plays a critical role in both municipal and industrial treatment plants by creating the optimal conditions for chemical and biological treatment processes. When added to wastewater, Lime raises the pH and increases alkalinity, helping to neutralize acidic effluents. This improved pH balance enhances coagulation, promotes the precipitation of heavy metals, and supports the efficient removal of suspended solids. It also creates favorable conditions for biological treatment by maintaining a stable environment for microorganisms. Lime is commonly used to precipitate metals such as iron, copper, zinc, nickel, and chromium, allowing them to be separated through sedimentation or filtration. It is also effective in reducing odors, improving sludge dewatering, and stabilizing sludge for easier handling and disposal. Due to its effectiveness, low cost, and wide range of applications, Lime remains one of the most essential chemicals for wastewater treatment, water purification, and industrial process control.
