Puroxi industry centre
Cooling Tower Water Centre
Cooling-water performance depends on microbiological control, clean heat-transfer surfaces, stable chemistry, filtration, blowdown and a complete Legionella water-management programme.
Understanding the application
Water Conditions Affect the Complete Operation
Puroxi does not begin with a product. We begin by understanding where the water comes from, how it moves through the site, what it contacts, what has already been tried and what the operation needs the water to do.
Legionella and other microbiological risk
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Scale, corrosion and heat-transfer loss
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Biofilm, sediment and basin algae
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
High makeup, blowdown and chemical demand
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.

How Puroxi approaches the water
A Site-Specific Treatment Pathway
Coordinate every change with the formal Legionella programme
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Use filtration, scale control and compatible treatment barriers
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Improve basin circulation or side-stream gas transfer where suitable
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Monitor cooling and water performance together
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Potential Puroxi treatment tools
Technologies Are Selected for What the Water Requires
Treatment areas
- Open cooling towers
- Biofilm and microbiology
- Legionella programme coordination
- Scale and deposits
- Suitable basin algae control
- Basin circulation and nano-bubble side streams
- Makeup water, blowdown and reuse
- Monitoring and cooling-performance verification
Technologies that may be considered
- Puroxi Nano Bubble Nozzles using ambient air, oxygen or another approved gas
- Puroxi Oxygen Generator for suitable on-site oxygen supply
- Quattro ultrasonic algae control where the water and biology are suitable
- Puroxi Oxygen Booster through a controlled water-test-based protocol
- Ultrasonic scale prevention, filtration, dosing, aeration and circulation
A technology appearing on this page does not mean it is suitable for every site. Puroxi may recommend one treatment method, a combination of independent systems or further testing before equipment selection.
Information required
What Puroxi Needs Before Recommending Equipment
Good design depends on accurate site information. Reports, photographs, drawings and operating history help prevent assumptions.
- Makeup water, tower design and heat load
- Cycles, conductivity and chemical programme
- Basin geometry, filtration and blowdown
- Microbiology, deposits and cleaning history
Relevant parameters may include temperature, pH, dissolved oxygen, salinity, conductivity, turbidity, hardness, alkalinity, nutrients, organics, metals, microbial information and algae identification, together with the process-specific information required for this industry.
Monitoring and verification
Measure the Water and the Operating Result
Required microbiological testing
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Approach temperature and heat-transfer performance
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Scale, corrosion and deposit condition
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Makeup, blowdown, conductivity and energy
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
The Puroxi process
Test. Design. Treat. Verify.
- Characterize the source and the operating problem.
- Define the objective, limitations and applicable requirements.
- Design the hydraulic, gas, treatment and monitoring arrangement.
- Commission, document, evaluate and refine the programme.
