MicroTERRA is a promising Mexico-based startup developing systems that use microalgae to turn fishpond wastewater into protein for fish feed.
A study shows that wastewater from recirculating aquaculture systems is suitable for microalgal cultivation and that sludge amendment to the wastewater increases production.
Shrimp hatcheries are highly dependent on continuous availability of clean water and proper treatment of effluents using sedimentation and biofiltration.
One simple method of treating high-nitrogen wastewater in shrimp aquaculture is the use of sequencing batch reactors, which are simple in design.
In pilot-scale research, researchers found that both sequencing and membrane batch reactors removed ammonia, nitrite and suspended solids with great efficacy.
A pilot project in Kentucky that uses wastewater effluent and decommissioned tanks at a water treatment plant has cultured over 70,000 phase II paddlefish.
