-->Acid Neutralizing Capacity (ANC) is the measure for the overall buffering capacity against acidification for a solution. ANC is achieved by raising the alkalinity of the water. To do this, a lime feeding system that will continuously supply a dose of saturated lime water (with a pH of 12) into the entrance tank is needed.

OBJECTIVE

The main objective of the team is to design a lime feeder system to deliver effluent with a pH of 12 (saturated pH of limewater) to be mixed in with the treated water to increase its pH. For efficient plant operation, the lime feeder design must be simple, easy to construct and install, and cost-effective. It must also be robust, avoiding the use of electricity and be easy to maintain, such that the operator will only have to add a specific amount of lime every 24 hours.
