Wastewater treatment stands as an essential pillar of contemporary industrial and urban progress, addressing environmental concerns.
However, the presence of pollutants in wastewater casts a significant shadow over natural resources and ecological equilibrium.
In this pivotal context, hydrated lime emerges as a trusted ally in wastewater treatment, lauded for its remarkable efficacy and consistent results.
Also referred to as calcium hydroxide (Ca(OH)2), hydrated lime takes on a pivotal role in the wastewater treatment process, showcasing a range of versatile functions.
Primarily, hydrated lime excels as a potent neutralizing agent.
Through its chemical reaction with acidic or neutral wastewater, it orchestrates a transformation towards a neutral or nearly-neutral state, aligning the wastewater with rigorous environmental standards.

Neutralization and Regulation:
Hydrated lime, an alkaline substance, is used for neutralizing acidic substances in wastewater, regulating pH levels to maintain an appropriate range within wastewater treatment systems. Proper pH levels assist other treatment steps in operating more effectively and prevent harm to aquatic environments.
Flocculation Aid:
Hydrated lime can form precipitates with suspended solids and metal ions in wastewater, facilitating their rapid settling. This aids in the removal of suspended particles and impurities from wastewater, reducing suspended solids discharge and improving water quality.
Phosphorus Removal:
Hydrated lime exhibits good performance in treating phosphorus in wastewater.
It can form insoluble calcium phosphate precipitates with phosphates, effectively removing phosphorus from wastewater and preventing phosphorus pollution that could harm aquatic life.
Disinfection and Sterilization:
Hydrated lime possesses disinfection and sterilization properties, helping reduce microorganisms and pathogens in wastewater to some extent. This contributes to enhanced sanitation and safety of wastewater and reduces risks associated with contact with water sources.
Ammonia Nitrogen Removal:
Hydrated lime reacts with ammonia nitrogen in wastewater to form insoluble calcium-magnesium-ammonium compounds, effectively removing ammonia nitrogen. This is significant in reducing ammonia nitrogen pollution in water bodies.
Improved Sludge Properties:
The addition of hydrated lime can enhance the structure and properties of sludge, making it easier to manage and dispose of. It assists in reducing sludge volume and treatment costs.
In summary, hydrated lime offers various benefits in wastewater treatment, including neutralization and regulation, flocculation aid, phosphorus removal, disinfection and sterilization, ammonia nitrogen removal, and improved sludge properties. It is an integral part of wastewater treatment processes, contributing to improved water quality, environmental protection, and more efficient wastewater treatment solutions.
