CocoWalk Lifestyle Center: Cooling Tower & Closed Loop Water Treatment

Project: CocoWalk Lifestyle Center
Location: Coconut Grove, FL
Scope of Work:
  • 2-Cell, 720 Ton Cooling Tower System
  • Less Than 4000 Gallon Closed Loop
EasyWater Equipment:
  • CTF – Cooling Tower Treatment (Model CTF-100)
  • Series C – Closed Loop Treatment
    (Model CLC-1000)

Problem

CocoWalk is an upscale lifestyle center located in the Coconut Grove neighborhood of Miami, Florida. This large complex has 30+ stores and services, including shops, restaurants and a movie theater.

This facility has a cooling tower system and plate and frame heat exchangers providing water for a heat pump system. The equipment provides air conditioning for all tenants. Like many cooling towers, CocoWalk was plagued with ongoing problems from:

  • Hard water scaling in there piping system and heat pumps
  • High bacteria counts
  • Hard water scaling in the cooling tower fill

Solution

CocoWalk purchased (1) EasyWater CTF-100 Treatment System for the cooling tower and (1)
EasyWater CLC-1000 to treat the closed loop heat pump system.

EasyWater’s CTF System is a unique, three-part solution

In the Fall of 2020, EasyWater received a purchase order for (2) CTF-360-S skid mounted treatment systems, a unique, three-part solution for cooling tower treatment and filtration:

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

EasyWater’s Series C System is an advanced closed loop treatment system that eliminates the need for chemical treatment:

  • Proprietary filtration media that continuously removes dissolved oxygen
  • Sub-micron, self-backwashing filter for the removal of sediment, debris,
    and bacteria
  • EasyWater No-Salt Conditioners to prevent and remove hard water scale
    deposits, biofilm, and bacteria.

RESULTS: COOLING TOWER WITH CTF SYSTEM

Our CTF Treatment System has continuously maintained low bacteria count, clear water, and no scale. A small amount of oxidizing biocide is used and properly maintained as a precautionary measure for Legionella.

CocoWalk is now seeing an impressive 80+% reduction in chemical use. There has also been significant savings in energy consumption through eliminating limescale build-up. In addition to these savings, CocoWalk no longer has to deal with the hazard of having multiple types of chemicals on site to treat their cooling towers.

AFTER Treatment – Bacteria dip slides continue to register 100 on a monthly basis.

RESULTS: Closed Loop with Series C System

The Series C Closed Loop Treatment System has continuously maintained low dissolved oxygen and corrosion rates in the system while removing dirt debris, and deposits that were in the system.

Corrosion coupons lost only .0692 mils/yr, which is beyond EXCELLENT according to the chart on the next page!

Before – Dissolved oxygen test results 5-6ppm

After 8 Months – Dissolved oxygen maintained at <1ppm

During the (8) month period the chilled loop corrosion rates were at 0.0692 mils per year.

Based on the chart above, the Series C System at CocoWalk provided results that were well below the 0.1 limit for having an EXCELLENT corrosion rate!

This test confirms that Series C provides superior corrosion control without using chemicals.
