Problem

140 First St Medical Labs, located in the East Cambridge Market, is a six-story, 238,934 square foot medical building.

They were concerned with the proximity of the discharge drift from their cooling tower system to the HVAC outdoor air inlet to the building since the water droplets could contain legionella. Consequently, the engineer contacted EasyWater for a solution.

The EasyWater CTF System was recommended to minimize legionella risk and help control:

Scaling in the cooling tower fill and chiller condenser tubes
Biofilm
Dirty turbid water
High bacteria counts

Solution

In March 2023, TG Gallagher Mechanical installed the EasyWater model CTF-425-S. It is a side stream treatment system, to manage scaling, corrosion, and bacterial concerns in the cooling tower system. On March 14th, an EasyWater technician performed the startup of the CTF System.

EasyWater’s CTF-425-S Cooling Tower Treatment System is a three part solution:

An EasyWater SedimentShield, sub-micron backwashing filter for the removal of sediment and bacteria
An Ultraviolet chamber for bacterial sanitization
(2) EasyWater No-Salt Conditioners to prevent and remove hard water scale deposits, biofilm, and reduce bacteria. The No-Salt Conditioners have the added benefit of preventing the hot UV lamps from scaling.

RESULTS

Within just three weeks, the cooling tower bacteria count went from over 10³ (4700 CFU/mL) down to 10⁰. In addition, the cooling tower sumps and fill were free of scale, algae and biofilm.

The owners of 140 First St. Labs are very pleased with the treatment results of the CTF System and intend to implement it in more facilities.

Prior to treatment, the water was very dirty and lab results from March 17th, 2023 indicated a high 10³ bacteria count

(6) months later, bacteria dip slides continue to show 10⁰ bacteria count and the sump and fill continue to be free of scale and biofilm
