Puroxi industry centre
Aquaculture Water Centre
Fish, shrimp and shellfish systems require water treatment designed around species, biomass, temperature, oxygen demand, feeding, beneficial biology and production risk.
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.
High oxygen demand from biomass and feeding
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Temperature-driven oxygen swings
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Algae, suspended solids and organic accumulation
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Stock risk during equipment or power failure
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Systems and applications

These photographs show genuine Puroxi equipment or approved application references. Final equipment selection and layout remain site-specific.
How Puroxi approaches the water
A Site-Specific Treatment Pathway
Nano-bubble oxygenation sized around biomass and peak demand
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Circulation that distributes oxygen without stressing stock
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Independent ultrasonic algae control only after species and food-web review
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Alarms, redundancy and emergency oxygen planning
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
- Finfish ponds, tanks and raceways
- Shrimp farming and beneficial diatoms
- Oysters, shellfish and nurseries
- Dissolved-oxygen support
- Nano-bubble gas transfer
- Circulation and solids management
- Suitable algae-control evaluation
- Monitoring and emergency planning
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.
- Species, biomass, density and production stage
- Pond or tank dimensions, flow and exchange
- DO, temperature, pH, salinity and feeding schedule
- Current aeration, mortality history and backup power
Water testing
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
Continuous or frequent DO and temperature
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Response at surface, middle and bottom locations
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Feed, behaviour, health and mortality observations
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Gas flow, pump pressure and backup readiness
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.
