Background
The Department of Natural Resources & Environment (DNRE) constructed a state-of-the-art fish research facility in partnership with the Salmon Tasmanian association and the Fisheries Research & Development Corporation. This bio-secure animal research facility adheres to physical containment level 2 (PC2) standards as specified in AS/NZS 2243.3:2010 and AS/NZS 2982:2010.
Objectives
The primary objective of the project was to meet the stringent PC2 requirements, particularly concerning the treatment of water effluent. According to the relevant Australian Standard (AS/NZS 2243.3:2010), all water effluent produced by the facility must be disinfected before being released into the municipal sewer system.
Challenges
The key challenge was to design a robust effluent water disinfection treatment system that could effectively handle the facility’s water effluent and ensure compliance with PC2 standards. Additionally, the system needed to be seamlessly integrated into the facility’s operations while maintaining a safe working environment.
Solution
A fish facility effluent disinfection system was engineered around a linear batch process involving reception, chlorination, and discharge. Key features included:
- A skid-mounted system with all necessary pumps, filters, valves, controllers, and a PLC control panel.
- External components such as tanks, level control, and essential pipework.
- A three-tank recirculation/batch system with sequential transfer and filtration stages.
- Chlorine dosing, recirculation, and discharge managed in sequence.
- Monitoring of free chlorine, pH, and ORP levels, with data logging to an SD card.
- An alert system for blocked filter bags.
- An FRP balustrade with three self-closing gates to ensure a safe working environment.
Outcome
The implementation of the effluent water disinfection treatment system by Southland Filtration successfully met the PC2 requirements, ensuring that all water effluent is disinfected before release. This not only guarantees compliance with Australian standards but also enhances the bio-security of the research facility.
In Summary
Southland Filtration’s provided the DNRE’s bio-secure fish facility with a reliable and efficient effluent water disinfection solution. This project underscores the importance of advanced water treatment systems in maintaining bio-security and environmental safety in research facilities.
