Puroxi industry centre
Oil & Gas Water
Produced and process waters vary widely. Material compatibility, chemistry, pressure, safety and operating objectives come before equipment selection.
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.
Produced-water chemistry and hydrocarbons
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Iron, sulphide, bacteria and scale
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
High salinity, temperature and pressure
This condition is evaluated in relation to the source water, system design, operating load and the required outcome.
Tank, pipeline and disposal or reuse constraints
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
Full produced-water characterization before technology selection
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Compatible oxidation, oxygenation or gas-transfer pilot testing
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Tank circulation and controlled treatment where appropriate
Treatment selection follows water testing, hydraulic review, material compatibility and the customer’s verification requirements.
Materials, ventilation and process-safety review
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
- Produced-water evaluation
- Storage and process tanks
- Oxidation and gas transfer
- Pilot testing and compatible materials
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.
- Detailed water analysis and hydrocarbon data
- Flow, pressure, temperature and gas conditions
- Tank and piping drawings with metallurgy
- Treatment objective, disposal route and site safety rules
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
Target chemistry and microbial indicators
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Scale, corrosion and fouling response
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Dose, gas, pressure and contact time
Record the baseline, treatment settings, operating changes and follow-up results so performance can be evaluated responsibly.
Safe operation and downstream compatibility
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.
