Experiment research on removing chloride in recycling cooling water with ultra-high lime and aluminum
Chloride is a deleterious ionic species in cooling water systems because it is important in promoting corrosion.It can be removed from cooling water by precipitation using the ultra-high lime with aluminum process.This research was conducted to study equilibrium characteristics of chloride removal by the process.Chloride removal reaction was found to complete within 2.5 hours and the removal efficiency decreases as the reaction temperature increases.Good chloride removal was obtained when the molar ratio among lime,aluminum and chloride is 5:2:1.Higher removal efficencies are available with the increasing of the initial concentrations; however,it keeps invariant when reaching a definite value.
