- Limestone is added to the coagulation flocculation process for forming solid particles larger than the reaction between small particles and colloids with poly aluminum chloride coagulant that can be precipitated. Limestone also serves to stabilize the pH after coagulation flocculation process. Analysis of the supernatant results coagulation flocculation process where the turbidity is measured with a turbidimeter that work on the principle of light scattering by colloidal particles, the measurement of total dissolved solids with Total Dissolved Solid Meter that works on the principle of electrical conductivity by particle ions dissolved in water and measuring pH with pH meters which work on the principle amount of H + ion concentration in the water. From the experiment results, the addition of lime is the optimum volume of 4ml gives the change of pH from 7.15 to 6.79; turbidity from 8.61 NTU to 0.17 NTU and total dissolved solids from 117.4 mg / L to 143.4 mg / L.
