Despite their relatively small footprint, low-space bioreactors deliver sustainable and cost-effective biological wastewater treatment, particularly in recirculating aquaculture systems, where ammonia removal is critical.
Category Innovation & Investment
The Soy-In-Aquaculture project in the Philippines has introduced low-volume, high-density cage culture production methodology for use with high-value marine species. The technology was developed to maximize farmers’ profits, improve productivity, reduce feed-conversion ratios and limit environmental degradation.
Increasing the heat recovery efficiency of a system can save both capital and operational costs. Contain water and keep exchangers clean.
Polyhydroxyalkanotes, or PHA, biodegradable biopolymers produced from sugar fermentation, offer a potential low-maintenance denitrification method for RAS.
Cavitation occurs in a centrifugal pump when the effects of low internal water pressure lead to impeller damage. Proper design and installation of pumping systems can help.
An intensive-culture recirculation system for farming European lobsters has been developed, with a pilot installation in Norway.
Emerging offshore aquaculture projects are proving they can endure hurricane-force winds, strong waves and high currents associated with major storms.
The performance of Pacific white shrimp was evaluated using three filtration systems: bead filtration, foam fractionation and pressurized sand filtration.
One solution to the problems with raceways is to convert them into a series of counter-rotating mixed cells that act as hydraulically separated round tanks.
