My reading of this was: dump it in a pond, manage the oxygen levels, and algea will basically out compete everything.
I assume that they need to seed it with the right version, to stop it becoming a stagnant oxygen free environment.
- Gys 5y agoThe article does not mention managing oxygen levels? They do mention fish living in the water (after the cleaning), so there must be oxygen in it.
- kamray23 5y agoAlgae blooms cause hypoxia by their decomposition at the bottoms of bodies of water. Through harvesting the algal biomass, no such decomposition can take place and a hypoxic environment is not created. In addition, algae produce oxygen, so as long as the algae are removed after, water might become more oxygenated through algal treatment.
- soco 5y agoUh I think they first clear the wastewater with said algae in some usual tank, then filter algae out and use the now clean water somewhere else, pisciculture or whatever. And the filtered algae biomass for biofuel.
- belorn 5y agoThe risk to oxygen levels might be significant lower if they are harvesting the algae and not allowing it to fall to the bottom.
- kamray23 5y agoI think the reading that you should have is, dump in in a treatment tank, cycle the water and scoop out the algae before the majority of the bloom decomposes, and you avoid hypoxic water post-treatment.
- KaiserPro 5y agoAha! yes, that would be the missing link. It makes sense as I suspect that they only bind to the heavy metals when its alive. It does say that the harvested algae can be used for biofuels, so I might be misreading that.
