Wastewater Treatment
Puroxi technologies can support oxygen transfer, oxidation, odour management and process stability within a complete wastewater design.
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.
Variable organic and hydraulic loading
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Low dissolved oxygen and anaerobic zones
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Odour, sulphide, sludge and foam
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Biofilm, fouling and difficult discharge targets
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 or aeration sized to oxygen demand
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Circulation and mixing designed around basin geometry
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Controlled oxidation where chemistry and biology permit
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Pilot testing integrated with the existing biological process
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
- Aeration and nano-bubble oxygenation
- Odour and sulphide conditions
- Oxidation and biological-process support
- Pilot testing and 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.
- Influent, effluent and process-water reports
- Average, peak and seasonal flow
- Basin dimensions, depth and retention time
- Current aeration, energy, sludge and odour data
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
Dissolved oxygen by location and depth
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
BOD, COD, TSS and relevant nutrients
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Odour or sulphide conditions
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Energy, sludge and process stability
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.
