Water Treatment Blogger [www.h2oside.com]

I am having so much fun watching the major chemical companies, especially those that have placed their entire marketing strategy on chemical treatment, make a complete fool of themselves by showing their ignorance (or should I say their flummoxing and befuddling campaign) about Silica based chemistry ..... Their sales forces are desperate and making remarks like "... where did all that silica go?...."

Here in the PNW (and anyone else in this range of make-up water) , regardless how well you passivate and follow cooling tower manufactures recommendations, your galvanized tower basin, tubes and support structure is going to still have W hite R ust appear and sometimes severely. You see, good passivation is important and should be practiced, however, all you have to do is just lose your chemical treatment or lose your solids for just a moment; more especially your pH (alkalinity) - you will fall right back into the conditions outlined by the AWT / CTI organizations that list the causes for WR in no time flat. To avoid extremely high HTI (holding time index), we need to run these chemical programs right on the edge of the WR domain. You see we have a serious corrosion problem up here where you can run the Ryznar Indices and find you have it > 12 - or run the LSI and get -2.6; you are doomed with galvanized. The good news is that more and more contractors and customer
