If they accumulate iron, they might also accumulate other heavy metals, so that could be a bit tricky to do with real waste streams.
Studies have shown this for half a century. Microalgae are also proven water cleaners. Yet they are not applied large scale anywhere. There are a few microalgae based fertilisers on the market whete I live though!
