Algae “scrubber” tackles harbor pollution

This “algal turf scrubber,” a long wooden sluiceway in which water is pumped over a bed of slimy green algae in a controlled tank could be the next solution to the Chesapeake Bay problems. It helps removes nutrients, suspended sediment and carbon from water and puts oxygen back into the water. So this could also be a solution to dead zones. You can also use the algae for fertilizer and fuel. But this project is still in small scale size so it might be a long time till we see this in the Chesapeake Bay.
