NEUTRALISATION OF ACIDIC EFFLUENTS WITH LIMESTONE

pollution. Currently, chemicals such as lime, sodium hydroxide and sodium carbonate are used for the neutralisation of acid water. Limestone can also be used which has the following advantages: low raw material cost, non-hazardous nature of material, low potential of accidental overtreatment, and production of a low-volume, high-density sludge.
