Installation and method for processing wastewater, comprising: a) providing wastewater for processing; b) reducing O2 content of said wastewater by unactivated aerobic digestion; c) subsequently to‘b’, eliminating substantially all O2 from said wastewater by anaerobic digestion; d) subsequently to‘c’, transferring said wastewater to a closed photobioreactor; and e) subsequently to‘d’, maintaining said wastewater in said photobioreactor in conditions favorable for algal photosynthesis, thereby allowing algae to grow in said photobioreactor. A method for growing algae is also disclosed whereby time, density and flow speed are controlled. The photobioreactor may have a conduit with two proportions of different cross sections. |
