The future of our planet may very well depend on the green conservation technologies that are developed and utilized today.  Although energy conservation, environmental planning, and reducing carbon footprints are all very important, preserving our fresh water supply should always be at the forefront.  Of all the water on planet earth, less than three quarters of one percent is fresh water available for human use.

The three greatest demands on our fresh water resources are crop irrigation… drinking water… and industry.  One of the most widely used industrial applications for water is in cooling towers.  A cooling tower is a simple piece of equipment designed to remove heat energy from water through the process of evaporation.

A comprehensive water treatment program is utilized on all cooling towers to control the major problems that can occur.  A scale inhibitor is used to control scale formation.  A corrosion inhibitor is used to control corrosion, and a biocide is used to control biological growth.

A programmable controller and commercial grade feed pumps are used to inject the correct ratio of these water treatments into the water based on monitored system variables.  Although conventional water treatment programs use similar treatment products to control scale, corrosion, and biological fouling, it is the scale inhibitor alone that determines the amount of bleed-off that is required to maintain system integrity.

On average, standard water treatment programs maintain cooling tower systems at three cycles of concentration, or less.  To maintain three cycles, the bleed-off rate will require 1 gallon of water to be dumped and replenished, for every 2 gallons of evaporation.

This represents a 33% waste.

In 1996, TERLYN Industries developed the Terlyn Cooling Tower Water Conservation Program.  This program is capable of maintaining virtually any cooling tower system at 50 cycles of concentration, thereby reducing the wastewater discharge requirement to only 2%.  Utilizing the Terlyn program at 30 cycles of concentration requires only one gallon of wastewater for every 29 gallons of water that are evaporated.

This reduces cooling tower wastewater discharge from 33% of the total water used, to only 2%.  This is a 33% reduction in the total water required by the cooling tower.  Although the chemistry behind this technology is complex, its performance is reached through a relatively simple process.

The Terlyn Scale Inhibitor has a molecular bonding strength that is 30 times greater than conventional scale inhibitors.  This bonding strength allows the Terlyn Scale Inhibitor to significantly increase the saturation point of the system water.

A simple analogy for this performance would be the comparison between Elmer’s® glue and Super Glue®.  Both have the ability to bond… One is simply much stronger than the other.  The Terlyn program incorporates industry standard corrosion inhibitors, biocides, and feed equipment to monitor and inject the proper ratio of treatment into the system.  The programs exceptional performance and water savings are achieved through Terlyn’s advanced scale inhibitor technology.

The unprecedented performance and conservation advantage of the Terlyn Cooling Tower Water Conservation Program will allow any company operating a cooling tower system to join the green global water conservation initiative.  More than 19 years of field experience in the practical application of this program gives us priceless knowledge and experience in maintaining cooling tower systems with only 3% wastewater discharge.

According to BOMA, the Building Owners and Managers Association International… commercial office buildings alone consume one-sixth of the world’s fresh water supply in their cooling towers.  Being green doesn’t have to be expensive or painful.  In Fact, With Terlyn, it’s actually easy and profitable.


Less than one percent of our planet’s fresh water is available for human consumption. According to BOMA 1/6 of that water is consumed in cooling towers.  With your help, we can prevent as much as half of that water from being wasted.

Now is the time for your building to start saving water.
