Centurion provides wastewater and sewerage treatment solutions designed to meet project requirements.
When selecting or designing systems, we consider factors such as influent flow rates and water quality, site conditions, budget, and the preferred treated effluent disposal method.
Our Wastewater Treatment Systems
Find the Right Wastewater Treatment System
The table below gives you a simple side-by-side view of your various wastewater treatment options. It shows what each wastewater treatment system is best suited for, from low-risk irrigation through to high-risk ocean discharge and process applications.
The chart also compares the performance of each system in terms of key water quality parameters like E. coli, BOD, total suspended solids, and nutrient removal. The higher the exposure risk and the stricter the water quality requirements, the more advanced the treatment system recommended.
It's a practical guide to help you make a decision, but if you need a hand, our team can assist - just contact us using the details below.
| Type of Treatment System | Exposure Risk (human contact) | Level of Nutrient Removal (nitrogen & phosphorus) | Best Suited for... | Summary |
|---|---|---|---|---|
| Sequencing Batch Reactor | Low | Moderate |
| Treats wastewater to a safe level for low risk uses. The system removes a moderate amount of nutrients and produces water that’s clean enough for the uses listed, with low bacteria levels and within safe chemical limits. |
| Sequencing Batch Reactor + Mediafiltration | Medium | Moderate |
| Treats wastewater to a higher standard for medium risk uses. It removes a moderate level of nutrients and produces water clean enough for situations with possible human contact, like outdoor or industrial areas where people may be nearby. |
| Sequencing Batch Reactor + Certified Ultrafiltration | Medium | Moderate |
| Treats wastewater to a high standard for medium risk uses. It removes a moderate level of nutrients and produces clean, disinfected water that’s safe for uses where people may be nearby or occasionally come into contact with it. |
| Sequencing Batch Reactor + Certified Ultrafiltration + Ultraviolet | High | Moderate |
| Treats wastewater to a very high standard, making it suitable for high-risk uses where direct human contact is likely. It removes a moderate level of nutrients and meets strict water quality limits, producing disinfected water that’s safe for everyday use around people. |
| Membrane Bioreactor (MLE Process) | Medium | High |
| Treats wastewater to a high level, making it suitable for medium risk uses. It offers high nutrient removal, producing cleaner water with lower nitrogen and phosphorus level - ideal for applications where environmental protection and public safety are priorities. |
| Membrane Bioreactor (MLE Process) + Ultraviolet | High | High |
| Treats wastewater to a very high standard, making it suitable for high-risk uses where direct human contact is expected. It delivers high nutrient removal and excellent water quality, meeting strict safety limits for bacteria and clarity - making it ideal for both residential and sensitive agricultural applications. |
| Membrane Bioreactor (4 Stage Bardenpho) | Medium | Very High |
| Treats wastewater to a very high standard, making it suitable for medium risk uses. It delivers excellent nutrient removal, especially for nitrogen and phosphorus, and produces clean, disinfected water that’s safe for settings where people may occasionally be nearby. |
| Membrane Bioreactor (4 Stage Bardenpho) + UV | High | Very High |
| Treats wastewater to an exceptionally high standard, suitable for high-risk uses where people may come into direct contact with the water. It offers very high nutrient removal and meets strict safety limits, producing disinfected water that's safe for sensitive residential, agricultural and urban environments. |
Note:
- Exposure risk from the Australian Guideline for Water Recycling: Managing Health and Environmental Risk (2006)
- Level of nutrient removal is determined by the DWER license. Indicative figures provided.
- Values show the level of treatment each system delivers, based on key water quality indicators. The lower the numbers, the better the treated water quality.
- All above treatment system will have post chlorination to have Free Chlorine Residual level between 0.2 – 2.0mg/L
- UV and UF to be certified by US EPA or CE(European)
