Information for those on the run
You can find all the benefits of the WCTI technology in this one document. There is of course a lot more information @ www.savingtowerwater.com

Relationships between hard and soft water programs
I have been asked about the relationship between traditional hard water chemical programs and our WCTI soft water approach. This will hopefully help those that want to know how these two approaches are related.
Silica species in equilibrium
This chart will show how traditional chemical programs compare to WCTI relative to the silica species. No longer is Silica our nemeses but rather here it works as means to essentially eliminate corrosion and at the same time keep ions in suspension at very high TDS
Some Q&A about ZLD Program - WCTI
WCTI Technology Zero Liquid Discharge Technology eliminates scale and corrosion in ZLD operation of cooling towers. Silica chemistry maintains heat transfer, prevents galvanized white rust, controls bio-fouling without chemicals. US 6,929,749 / Silica Scale Control US 6,949,193 / Silica Scale Control US 6,998,092 / Corrosion Inhibition/Silica US 7,122,148 / Corrosion Inhibition/Silica Q&A Is it true that the make-up water stream for WCTI technology has to be almost entirely softened (Ca and Mg removed)? A: Correct, the process requires sufficient softening of makeup water to maintain total hardness levels at less than 30 mg/L as CaCO3 in the tower water to maximize water conservation and performance. Higher hardness levels can be supported at higher TDS due to common ion effect (example, higher hardness in seawater effect). Lower COC with some blow down from low hardness makeup can be maintained with results comparable to traditiona...
New site with new technology
Waterside Asset Management introduces a new web site to introduce a promising new technology that uses existing water chemistry to eliminate chemical use and at the same time eliminate tower bleed. Visit www.savingtowerwater.com
You think you have seen it all!
If you have a hook up to feed product like this, ask your supplier for your money back. What we have here is a need to get three chemical products into the tower the wrong way. Yes, these small towers are tough to treat - simply because these evaporative cooling towers are not set up from manufacturing to treat water. It would be best to request a sample flow line / chemical feed to be set up at the factory. One could also go with a technology that does not need chemical. Anything would be better than trying to inject chemical in the same line. One good suggestion would be to try the new zero bleed technology from Water Conservation Technology that does not use products and serves to the lay up period if you are in that kind of climate. In some areas of the country if you are not concerned about water savings just set the bleed to a low cycles and not treat the water and with only a biocide once in a while as needed. After all some of these small systems only have 100-200 gallon...
