One of the positive things about Alaska salmon enhancement hatcheries is that they are often remote. That means a supply of cool, clean water coming from streams undisturbed by development. But that remoteness can also be a negative, when operators are trying to retain staff.

Membrane biological reactors (MBRs) are used for municipal, industrial and agricultural wastewater treatment to remove nutrients, organics and solids from concentrated effluents. MBRs utilize fine-pore membranes (typically < 0.1 µm) that create a clean, low-solids filtrate, while associated aerobic and anoxic processes functioning within an activated sludge facilitate nitrification and denitrification, respectively.
