The Cooling systems used at most commercial buildings, including offices, universities, hospitals and stores consume vast quantities of water.
These cooling systems can also develop mineral scales and microbes which lead to increased water and energy consumption and negative environmental impact.
Mineral scales consist mostly of carbonates of calcium and magnesium forming on heat-exchange surfaces.
These mineral scales makes heat transfer inefficient and increases the use of energy on the system.
Microbial growth can lead to the formation of biofilms which in turn also decreases the exchange efficiency.

High levels of biocide intended on cleaning up the water and preventing biofilm on heat exchange surfaces causes several effects.
Increased corrosion of system components.
Increased risk of system leaksMetal-containing byproducts of corrosion
and additional biocide are discharged with the cooling water
Whenever water is discharged it is called a “blowdown.”
In other words, pollutants are released in the wastewater and fresh water is used to replace the “blowdown.”

Before 3D TRASAR technology, other companies traditionally used antiscalants and antimicrobials at regular intervals or at best.
Sodium Aluminate was first used to help stop microbial growth and to keep the heat exchange surfaces clean.
Sodium Aluminate also helps to remove Silica and Phosphates.

Sodium Aluminate also helps to remove Silica and Phosphates.
However when there was a “blowdown,” Silica and Phosphates still entered our environment.
Silica is dangerous in small quantities over time, OSHA allows 0.1 mg/m3.
Small inhalation can cause silicosis, bronchitis, or cancer, due to the formation in the lungs decreasing lung capacity.

Instead of on a fixed schedule
3D TRASAR technology helps monitor the condition of cooling water continuously and add appropriate chemicals only when needed.
This technique helps to Save water and energy Minimize the use of water-treatment chemicals Decrease environmental damage from discharged

What does the 3D in 3D TRASAR Technology stand for?
Detects if the parameters are changing
Determines the correct course of action
Delivers exceptional economic and operational advantage
3D TRASAR uses unique chemistries, sensors, algorithms, hardware and software to provide online, real-time performance-based detection ability.
The main sensor is the Nalco Corrosion Stress Monitor which detects and responds to preboiler corrosion stress in real time, delivering direct measurement under actual operating conditions.
The Nalco Corrosion Stress Monitor helps prevent by measuring and reacting to the net
oxidation/reduction potential of the water. The monitor determines the corrective action and
responds in real-time by changing oxygen scavenger or metal passivator feed to protect the system.

The Controller used is the 3DT-5000 Controller which helps to collect the pH, ORP, conductivity and turbidity data. It also incorporates two corrosion sensing probes, which helps to calculate the systems volume, recirculation, make-up, blowdown, and heat rejection rates.
• The beauty of 3D TRASAR is that it is a universal device all
wrapped in one.
• It features contain a Scale Control, a Bio-Control, and a Corrosion Control.
• For the Scale Control, it helps to detect the upset preceding a scaling event and takes the action of preventing one again, when founded the 3D TRASAR will increase stress to help minimize operating cost.
• The Bio-Control unit is only applied when the bio-activity in the water increases or decreases.
• Corrosion control helps by combining advanced control capabilities with innovative new corrosion
inhibition chemistry to provide the best solution to your problem.

The boiler uses a fluorescent tagged scale dispersant polymer with an inert fluorescent tracer
This was added to provide scale/deposit inhibition, particle dispersion and to enhance activity of corrosion inhibitors.

Resazurin, which is another fluorescent molecule, changes its fluorescent signature when it interacts with respiring microbes.
Is used for the real-time test for measuring planktonic and sessile bacteria.
By adding Resazurin, this generally helps reduce the use of biocide and also prevents biofilm from building up on surfaces and maintaining efficient heat transfer.
