Puroxi industry centre
Marinas & Canals
Restricted circulation, fuel-sensitive operations, algae, odour and biofouling create distinctive water-management challenges.
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.
Stagnant zones and restricted circulation
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Algae, odour, sludge and low oxygen
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Fuel-sensitive operations and debris
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Biofouling on docks and infrastructure
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Systems and applications

How Puroxi approaches the water
A Site-Specific Treatment Pathway
Map circulation, depth and dead zones
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Use independent ultrasonic algae control where suitable
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Add nano-bubble oxygenation or circulation as a separate system
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Phase installations and document water response
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
- Circulation and aeration
- Algae and water clarity
- Odour and stagnant zones
- Biofouling and infrastructure protection
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.
- Plan, bathymetry, area, depth and volume
- Tides, inflows, salinity and circulation
- Algae, DO, sludge, odour and aquatic life
- Power, anchoring, navigation and installation restrictions
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
DO and temperature at representative points
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Algae, clarity, odour and photographic record
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Pump, gas and ultrasonic operation
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Seasonal response and maintenance
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.
