Bioretur converts aquaculture waste, or sludge, into fertilizer as demand for “circular economy” technologies grows.
Study evaluates if controlling maturation stage during seafood sludge composting through turning improves the process in comparison to static composting.
To design a settling basin, know the size distribution of particles, estimated rate of inflow and determination of the smallest particle size to be removed.
In modifying its infrastructure and related pond management, QVD Aquaculture uses floating water plants to remove nitrogen and phosphorus from the discharge water. Sludge pens capture sludge at ponds for later reuse.
A benefit of aeration is the mixing of pond water. Similar to biotechnological reactors, microbial processes are more effective in mixed pond water.
