Sodium Sulphate deposits in heat exchanger made out of Nickel Plate
I work in the Chemical Company that manufactures bleach.
Over couple of months there has been sulphate deposits in the heat exchanger made out of nickel plates. The use of the heat exchanger was to get the caustic to cool down to low temp of 80 F. Every two weeks we are having to clean up the exchangers because of the deposits of sulphate. Is there any way to trap sulphate before it gets to heat exchanger ?

Calcium sulphate fouling of heat exchangers is common on heating coils, but I haven't heard of it on a cooling coil before.
Try to identify the cation in the sulphate scale. Maybe you can eliminate the scale by eliminating it.
