Protector Australia’s EnviroSave system is currently undergoing the final stages of the SQIDEP (Stormwater Quality Improvement Device Evaluation
Protocol) approval process. The system has been subjected to comprehensive testing to assess its efficiency in treating stormwater runoff. Below are the preliminary results, including key performance metrics on flow rates, pollutant removal, and water quality improvement.
TESTING RESULTS:
1. Flowrate Performance
EnviroSave’s performance in handling different flow rates was tested under various stormwater conditions. The system’s ability to manage both low and high flow rates ensures that it can handle stormwater runoff efficiently, reducing the risk of flooding and contamination during storm events.
| Test Condition | Flow Rate | Expected Flow Rate | Observed Flow Rate | Efficiency (%) |
|---|---|---|---|---|
| Low Flow Event | 10 L/s | 10 L/s | 10 L/s | 100% |
| Medium Flow Event | 30 L/s | 30 L/s | 29 L/s | 97% |
| High Flow Event | 60 L/s | 60 L/s | 58 L/s | 97% |
2. Pollutant Removal Efficiency
The EnviroSave system demonstrated exceptional performance in removing pollutants from stormwater runoff. Key pollutants tested include sediment, hydrocarbons, and gross pollutants. The system’s multistage filtration and self-cleaning features contributed to its high efficiency.
| Pollutant Type | Concentration Before Treatment (mg/L) | Concentration After Treatment (mg/L) | Removal Efficiency (%) |
|---|---|---|---|
| Sediment | 350 | 12 | 96% |
| Hydrocarbons | 100 | 5 | 95% |
| Gross Pollutants | 1500 | 50 | 97% |
3. Water Quality Improvement
The EnviroSave system’s impact on water quality was measured by comparing pre- and post-treatment water quality parameters, including pH, turbidity, and dissolved oxygen levels. The system showed a significant improvement in water quality, ensuring it meets regulatory requirements and protecting local water bodies.
| Water Quality Parameter | Before Treatment | After Treatment | Improvement (%) |
|---|---|---|---|
| pH | 6.5 | 7.2 | +10.8% |
| Turbidity (NTU) | 15 | 3 | -80% |
| Dissolved Oxygen (mg/L) | 2.8 | 6.5 | +132% |
4. System Maintenance and Self-Cleaning Performance
The EnviroSave system’s self-cleaning feature significantly reduces maintenance needs, making it a cost-effective solution for long-term stormwater management. The system effectively removed 85% of accumulated sediment through its automatic backwash feature, reducing manual intervention.
| Maintenance Parameter | Frequency | Self-Cleaning Efficiency | Manual Intervention Required |
|---|---|---|---|
| Sediment Removal | Monthly | 85% | Low |
| Oil & Hydrocarbon Removal | Quarterly | 90% | Moderate |
Next Steps & Conclusion
EnviroSave is now approaching final approval under the SQIDEP, with all tests showing that it not only meets but exceeds expected performance levels. Once fully certified, Protector Australia will be able to offer this solution with even greater confidence, knowing that it provides exceptional environmental and cost-saving benefits.
We look forward to receiving full SQIDEP certification and expanding EnviroSave’s availability to help manage stormwater more sustainably.
