The basis of savings for this measure is the cost reduction achieved by
partially softening city water make-up to the condenser water system
(“CWS”) and increase cycles of concentration (CoC) to reduce condenser
water blowdown. Typical city water contains elevated amounts of minerals
(most notably total dissolved solids, hardness, and silica) which limits its
usefulness as a CWS makeup source.
As such, this measure includes both
dual softeners, and a side stream filtration unit to partially soften, provide 5-
micron filtration to the CWS system, and control system blowdown. increase
the operating cycles of the cooling tower. This allows for reduced CWS
blowdown rates, with a concomitant savings in sewer discharge.
With simple installation on a sidestream loop of the existing cooling system,
our equipment controls the key parameters of conductivity, and blowdown to
increase the existing cycles of concentration and maintain stable tower
chemistry based on the incoming water quality.
An Aqualogix Water Savings System is installed at the Lloyd D George Federal Courthouse in Las Vegas Nevada.
Aqualogix is currently participating in the GSA Proving Ground and DOE High Impact Technologies study, hosted by GSA, and performed by the National Renewable Energy Laboratory (NREL).
