Some wise person once said that "for every action, there is an equal and opposite reaction" . Hmm.... In fact, I think he may have had an apple drop on his head.  There is another saying that for every action there is a consequence - some call this Karma. So when we look at the actions taken in the field of water treatment in cooling water, there must be some consequence to our actions.

WCTI has forever changed the way the industry has thought of cooling water treatment by simply changing man's chemically engineered design back to Mother Nature's manifestations...  WCTI is nothing more than thinking of Newton's 3rd Law in the reaction that takes place in the ion exchange resin by the one to one exchange of Ca/Mg for Na going to the tower make-up - - after all there is an equal and opposite reaction here right?

Some might say that in our efforts to use water in a cooling tower, it must result in "blowdown" or more commonly known as tower bleed. If we do not, we must be willing to live with the consequences of scale, corrosion and bio-problems etc...  Water treatment, therefore, in open cooling systems must result in the bleed of the concentrated solids caused by evaporation resulting in 15 - 40% of the incoming water going down the drain. Oh no! - I almost forgot, there are chemicals that are needed to mitigate these consequences at minimal, however, bleed is still needed to manage the product limitations (we refer to this treatment as index chemistry).

Alas, we have treated one set of consequences with another set of consequences - i.e. costs of excess water use still remains and now we have hazardous materials going to the environment.  This might be thought of as bad Karma!

With our WCTI Zero Tower Bleed Silica Based non-index program, and its 98% reduction in system water use, our elimination of chemicals has allowed us to address the consequences of water treatment without any further negative consequences - I like to think of this as good KARMA!

How is your Karma?

Addressing all aspects of your Waterside Assets

The owner of Water Conservation Technology International, Dan Duke has given the industry an amazing tool that gets a lot of “press” these days on water conservation. I firmly believe that reducing the total plant discharge from their cooling towers system from a range of 12-40% to less than 2% (mostly less than 1%) does warrant the good press and yes it is what seems to be driving a lot of customers to the WCTI process.

However, I like to believe that in areas where:

  • Scale was the real problem, WCTI chemistry has removed that obstacle by controlling hardness and all that it entails.
  • Corrosion was the problem, that problem has been eliminated or substantially reduced from that of index chemistry programs by using what mother nature already has given us with silica based chemistry.
  • Bio-fouling was a problem, there is now no more bio-film or water borne deposits on WCTI Chemistry.

So for me, I like to think of it as also being about the RESULTS!.

I think it is safe to say that there are other areas of your plants’ waterside assets – such as KW savings, that have not been brought to the forefront as much as it should. You see, this is rather simple actually, in that the bio-film removal and scale elimination has lowered most if not all condenser “approach temperatures” that are on the WCTI program - which in some cases can surpass the water savings.

Many plant engineers and managers are very much aware of their approach temperatures, however they may not be relating too, or being educated on how these seemingly intangible “waterside" measurements can have big savings along with water conservation using WCTI's patented silica based chemistry. I see myself working more and more with the local folks from chiller manufactures’ to get a true consensus on what really translates into KW savings. Their list is long, but undisputed, is how important tube cleanliness is and on how it translates into or from lower approach temperatures – resulting in lower power (KW) use.

WCTI is the only program that addresses all aspects of “waterside asset management” and at the same time provides a safer environment for now and the future. Test us on it, give us a challenge and let’s talk!
