Nitrogen-water tower

Hello,
cooling water contains various salts,dissolved solids,biological organism and various other compounds.sulphuric acid is dosed continuously to maintain pH.Also different polymeric and non-polymeric chemicals are dosed which work as dispersants,corrosion inhibitors and biocides.It has been found that when cooling water is rapidly cooled from 30degree celcius to 5 degree celcius,1st in Nitrogen-water tower and thereafter in a refrigeration unit,deposits are formed on the wall of the tubes. The main component of the deposit is possibly calcium carbonet.
I want kinetics of the process of deposition and a way so that the deposition does not take place even in slightly alkaline system.
