Drawings Nutrients From Seafood Processed Wastewater

When fish are filleted in a seafood-processing plant, or when shrimp and shellfish are boiled, a lot of wastewater is generated. Currently, that water is simply discarded. An experimental new system, however, is able to draw much of the nutrients from it – and those nutrients could have a number of uses.

In a nutshell, the process involves first treating the water in such a way that the proteins and fats clump together. In the presence of air bubbles, those clumps then float to the surface, where they can be retrieved. The end products consist of a nutrient-rich liquid and semi-solid biomass.
