🌟 [ 77 ]   When Tiny Creatures Solve Big Problems: Wastewater Treatment With Microalgae

( 3899 viewed : 100 like : 7 comments ) Can we grow #microalgae in the #wastewater of greenhouses and why should we do it?

The wastewater of #greenhouses is not waste. This irrigation water, which is not used by plants, contains residual nutrients from fertilisers, such as nitrate and phosphate. Microalgae need these nutrients to grow, and when we cultivate them in the wastewater from soilless greenhouses, they extract these nutrients from the water as they grow.

It is important to treat agricultural effluents before they are released to prevent nitrates from accumulating in the environment. And with the circular concept of REALM, this treatment can be cheaper and more sustainable than conventional wastewater treatment systems.
