What is the primary function of lime when treating sludge?

To reduce odor
To promote denitrification
To provide nutrients for bacteria
To neutralize acidity

The correct answer is: To neutralize acidity

The primary function of lime when treating sludge is to neutralize acidity. In wastewater treatment processes, sludge can often have a high level of acidity due to various organic and inorganic compounds. Lime, which is a strong alkaline material, is added to the sludge to elevate the pH level, making the environment more neutral. This neutralization is important because it helps to stabilize the sludge, reduces the solubility of heavy metals, and can promote the effectiveness of other treatment processes. By managing the pH level, lime not only aids in improving the overall treatment process but also mitigates issues associated with acidic sludge, such as odor and corrosion.
