Abstract

A method of removing nitrogen-bound nitrate from at least one of groundwater, surface water, or waste water is disclosed. The method includes providing contaminant-containing water from groundwater, surface water, and/or waste water sources. The method further includes adding the contaminant-containing water to an algal photobioreactor system. The method further includes adding an alga culture to the alga photobioreactor system. The method further includes adjusting temperature, CO2 concentration, pH, light wavelength, and/or light intensity in the algal photobioreactor system to optimize the growth of the algae. The method further includes separating the algae from the water and harvesting algal biomass.
