Improving water quality & reducing energy use
The challenge:
To validate BioGill Nano-Ceramic Membrane™ capability as an effective biofiltration unit in a RAS (Recirculation Aquaculture System). The key measures are to:
-
Reduce energy usage and energy costs while delivering improved water treatment results.
-
Maintain or reduce levels of ammonia, nitrite and nitrate required for the optimal growth and wellbeing of the brood stock (Mulloway).
The solution:
To replace the existing high-energy current biofiltration system in the RAS, with a gravity-feed, low-energy use, above-ground BioGill bioreactor.
The results: (6 month interim report)
The main advantage of BioGill technology in aquaculture environments, is that BioGills work with the existing cultures in the pond water. No chemicals, no bacteria and no microorganisms are added. Instead, BioGills harnesses the power of Mother Nature in a completely healthy, proven, safe and natural system for the treatment of aquaculture pond water.
Read the latest report on BioGill's performance on a broodstock tank at the Port Stephens Fisheries Institute, NSW, Australia, prepared by Dr Tim Charlton. The key findings are that BioGills in a recirculating aquaculture system for a hatchery:
- maintained or improved water quality.
- allowed zero water exchange in the latter stages of the project (23 weeks)
- reduced energy usage
- maintained breeding performance and health of the broodstock.
