A letter to the Editor of AQUA magazine:
August 18th, 2010
To the Editor,
I wish to applaud Aqua Magazine for its commitment to an Annual Green Issue and the excellent graphics, as always. I do need to correct a few misstatements of fact and point out some glaring omissions.
A salt to chlorine generator is the least environmentally friendly way to sanitize a swimming pool, regardless of the filtration method employed but especially with the water wasting method of diatomaceous earth filtration. This also assumes the DE filter uses the proven perlite media and a separation tank to rid the perlite/chloride and cyanuric acid compounds. California alone has invested millions of dollars and years to salinity analysis.
I cannot accept the glaring omissions on the Pentair Intelliflo pumps, zeolite or glass filter medias. At least 50% water and electrical savings are achieved with these five year old technologies with many reports of 80%.
Performance aside, rating a DE filter as being more environmentally friendly than a cartridge filter is laughable. One may only conclude that the pool designer fears the murky/green water in evidence at a surprise tour of a $250,000 project were the more “environmentally friendly” filter to be employed.
For the record, we do not sell pumps (have hundreds of U.S. customers who have achieved 50 to 80% KW savings as reported to us with the Intelliflo bought from their dealer) and have thousands of installed sites with zeolite or glass that report 50 to 75% water and chemical savings, both residentially and commercially.
We continue to give away free glass filter replacement media for sand filters, including the shipping to any company in the pool business that has not seen the 2 micron outcome and once monthly backwash. I challenge the competitive zeolite producers to do the same in the interests of education and the environment.
Respectfully,
