The main objective of the team is to design a lime feeder system to deliver effluent with a pH of around 12 +(saturated pH of water) to be mixed in with treated water to increase its pH. For efficient plant operation, the lime feeder design must be simple, easy to construct and install, and be cost-effective while also being robust enough as to avoid using electricity and to not require maintenance more than once a day.
