Find the Right Wastewater Treatment System for your Site
Different wastewater streams require different treatment approaches. The right system depends on your wastewater type, flow rates, discharge limits and whether treated water will be reused.
Use this guide to match your application with the most suitable treatment approach.
Scenario | Typical Sources | Key Challenge | Recommended System |
| Heavy equipment washdown and workshops | Truck washdown, workshops, servicing areas | Oil, grease, suspended solids | OWS + DAF + filtration |
| Process water and industrial streams | Mining processes, industrial discharge | Variable chemistry, high solids, nutrients or metals | SBR or MBR + pre-treatment |
| Workforce accommodation | Showers, kitchens, laundry | Organics, nutrients, pathogens | SBR or MBR |
| Stormwater and runoff | Hardstands, laydown areas, vehicle movement | Sediment, hydrocarbons, peak flows | Separation + buffering + targeted treatment |
| Mixed site wastewater | Combined washdown, camp and process water | Changing loads and compliance risk | Modular SBR or MBR systems |

Compare Wastewater Treatment System Performance
Different treatment systems achieve different water quality outcomes. The right choice depends on the intended reuse application, environmental discharge standard and level of human exposure required. The figures below provide a practical comparison of common system types and the treatment standard each can achieve.
| System | Exposure Risk | Nutrient Removal | Best Suited For | Typical Water Quality Outcome |
| SBR | Low | Moderate | Sub-surface irrigation, low-risk reuse | BOD < 20 mg/L, SS < 30 mg/L, E. coli < 1000 cfu/100mL |
| SBR + Filtration / UF | Medium | Moderate | Dust suppression, industrial reuse, restricted-access irrigation | E. coli < 10 cfu/100mL, Turbidity < 5 NTU |
| SBR + UF + UV | High | Moderate | Urban irrigation, internal reuse, higher-contact applications | E. coli < 1 cfu/100mL, Turbidity < 2 NTU |
| MBR (MLE Process) | Medium | High | Industrial reuse, environmental discharge | TN 10–15 mg/L, TP < 2 mg/L |
| MBR + UV | High | High | Public contact reuse, agriculture, internal non-potable reuse | E. coli < 1 cfu/100mL, high clarity effluent |
| MBR (4 Stage Bardenpho) | Medium | Very High | Nutrient-sensitive discharge, advanced reuse | TN < 10 mg/L, TP < 1 mg/L |
| MBR (4 Stage Bardenpho) + UV | High | Very High | Unrestricted reuse, sensitive receiving environments | Highest treated water quality and very low nutrients |
What This Means for Your Site
- Low-risk reuse applications such as sub-surface irrigation can often be achieved with an SBR system.
- Industrial reuse or applications with possible human exposure generally require additional filtration and disinfection.
- Nutrient-sensitive environments or stricter licence conditions often require advanced MBR treatment.
- Higher-contact reuse applications such as unrestricted irrigation or internal non-potable reuse usually require UV disinfection and tighter water quality control.
Choosing the wrong treatment level can lead to non-compliance, costly upgrades and unnecessary operating complexity. We help clients select the right system from the start so the plant matches both site needs and approval requirements.

Our Industrial Wastewater Treatment Technologies
Our systems combine proven treatment technologies selected to suit your wastewater quality, site constraints and treated water objectives.
Pre-Treatment
Pre-treatment removes solids, oils and grease before biological treatment, helping protect downstream equipment and improve whole-of-plant performance.
Typical technologies include:
- Oily Water Separators (OWS)
- Dissolved Air Flotation (DAF)
- Lamella Clarifiers
Best suited for workshop wastewater, washdown water, contaminated stormwater and industrial process streams with high solids or hydrocarbons.
Biological Treatment
Biological treatment removes organics and nutrients from wastewater and forms the core of most industrial and sewage treatment plants.
Sequential Batch Reactor (SBR)
A reliable, cost-effective option for moderate treatment requirements, remote sites and lower-risk reuse or discharge applications.
Membrane Bioreactor (MBR)
A higher-performance solution that combines biological treatment with membrane separation to achieve better effluent quality, improved nutrient removal and suitability for tighter discharge or reuse standards.
Filtration and Polishing
Polishing treatment improves final water quality by removing fine solids, bacteria and remaining suspended matter.
Typical technologies include:
- Media filtration
- Ultrafiltration (UF)
These stages are often used where treated water is intended for reuse or where stricter environmental performance is required.
Disinfection
Disinfection is used where treated effluent requires pathogen reduction for reuse or higher-contact applications.
Typical technologies include:
- Ultraviolet (UV) disinfection
- Chlorination systems
This stage is particularly relevant for irrigation, internal non-potable reuse and higher-exposure applications. The treatment selection matrix shows that UV-supported systems are typically used where the risk of human contact is higher.
Sludge Handling
Sludge handling systems reduce sludge volume and make storage, transport and disposal easier and more cost-effective.
Typical technologies include:
- Sludge dewatering systems
This helps reduce disposal costs and improve whole-of-site waste management.
Built for Remote & Industrial Environments
Centurion wastewater treatment plants are available as containerised and modular systems designed for remote, harsh and space-constrained sites.

Questions & Answers
What is the best industrial wastewater treatment system for my site?
The best system depends on your wastewater type, contaminants, flow rates and discharge or reuse requirements.
- SBR systems are typically suited to lower-risk applications and simpler wastewater streams
- MBR systems are used where higher treatment performance or stricter compliance is required
- Additional filtration and disinfection may be needed for reuse or higher exposure applications
We assess your water and recommend a system that meets your performance and regulatory requirements.
What is the difference between SBR and MBR wastewater treatment systems?
The key difference is treatment performance and water quality:
- SBR (Sequencing Batch Reactor)
- Lower cost and simpler operation
- Suitable for moderate treatment requirements
- MBR (Membrane Bioreactor)
- Higher effluent quality and nutrient removal
- Suitable for reuse, strict discharge limits and sensitive environments
MBR systems are typically selected when compliance requirements are tighter or water reuse is required.
Can treated wastewater be reused on site?
Yes. Treated wastewater can often be reused for:
- Dust suppression
- Irrigation
- Washdown
- Firewater systems
- Industrial processes
The level of treatment required depends on how the water will be used and the level of human exposure. Higher-quality reuse typically requires filtration and disinfection (e.g. UF and UV).
How do I know if my wastewater will meet discharge regulations?
Compliance depends on achieving the required limits for parameters such as:
- BOD (Biochemical Oxygen Demand)
- Suspended solids (SS)
- Nutrients (nitrogen and phosphorus)
- Bacteria (E. coli)
We design treatment systems based on your discharge licence or regulatory requirements to ensure compliance and avoid costly upgrades later.
How quickly can a wastewater treatment plant be deployed?
Containerised modular wastewater treatment plants can typically be:
- Delivered and installed faster than traditional builds
- Commissioned with minimal site works
- Expanded or relocated as site requirements change
Rental systems are often available for rapid deployment where immediate compliance is required.
Can I rent a wastewater treatment plant instead of buying one?
Yes. Many clients choose rental or rent-to-buy options to:
- Reduce upfront capital costs
- Support temporary or early-stage projects
- Maintain compliance while permanent infrastructure is developed
This approach provides flexibility while ensuring your site remains operational and compliant.
What level of operator involvement is required?
This depends on the system and application:
- Simpler systems (e.g. SBR) require basic monitoring and routine maintenance
- Advanced systems (e.g. MBR with reuse) may require more oversight
Centurion systems are designed for operational simplicity, and we also offer:
- Operator training
- Remote monitoring
- Full-service operation and maintenance
This ensures your plant runs reliably without placing unnecessary burden on your team.
