Bioremediation of organic compounds in water via microalgae

A method for organic compound removal from a solution, comprising:

• extracting one or more hydrocarbons from an underground geologic formation,
• wherein the extracting forms a hydrocarbon composition and a produced water,
• wherein the produced water comprises at least a portion of the one or more hydrocarbons and one or more salts,
• mixing the produced water with a domestic wastewater to form a solution,
• contacting a microalgae feedstock with the solution in a bioreactor,
• wherein the microalgae feedstock is a Chlorella sorokiniana,
• wherein the produced water comprises an acetate,
• wherein the domestic wastewater comprises nitrogen and phosphorous,
• removing the one or more hydrocarbons, nitrogen, and phosphorous from the solution by algal consumption with the microalgae feedstock,
• wherein a total lipid content of the microalgae feedstock is 13 to 17% based on a dry weight of biomass,
• wherein the one or more hydrocarbons are removed in an amount of 80 to 90 wt. % based on a total weight of the one or more hydrocarbons in the solution before the removing,
• wherein the nitrogen is removed in an amount of 70 to 85 wt. % based on a total weight of the nitrogen in the solution before the removing,
• wherein the phosphorous is removed in an amount of 90 to 100 wt. % based on a total weight of the phosphorus in the solution before the removing.
