Integration of microalgae culture as a natural-based solution for wastewater treatment

The age of Anthropocene makes it imperative that we find ways to tackle pollution and stay within planetary boundaries limits, one these is nutrients availability. From a point view, the release new reactive nitrogen should be 25% current level, equal yearly about 35 million tons. Instead discharging N- P-rich wastewater into coastal inland waters, use same microalgae growth for useful purposes in microalgaebased treatment, since cultivation algae requires addition nutrients; mainly nitrogen, phosphorus potassium. In turn, cost reduction removal phase treatment stages, water reclamation reuse maintenance ecological balance aquatic terrestrial ecosystems. Therefore, this work deals with eutrophication issue naturebased solution aims investigate ability green remove from hypereutrophic try producing biogas reduce consumption fossil fuels greenhouse gas emissions.
