75-06: The Use of Ion Exchange Resins in Cooling Tower Technology

The treatment of water for coolant water towers by means of ion exchange 
resins is not a new concept and various studies have been made which have 
supported the need of such technology. Although this need and technology 
has been known for years, very few coolant tower systems employ ion exchange 
techniques today. In many respects, the operation of a cooling tower is 
quite similar to that of a boiler. If the make-up water to the tower 
is not treated and if the tower is not "blown down11 regularly, scaling 
and corrosion will be excessive and costly
