- Abstract
The approach uses eight Air-Lift Photo Bio-Reactors designed to increase the algal morphology for easy harvesting and dewatering, and recycling and reuse. By culturing both a polyculture, along with three pure cultures from UTEX of both fresh water and salt water species. Skeletonema costatum (salt water), Dunaliella salina (high-brackish saltwater), and Chlorella sp. (fresh water), by altering the concentration of the effluent, the algal processing will theoretically remove organic substances from the water that are otherwise inhibitory to the reuse prospects for the water. Our goal in the indoor cultivation in conjunction with the ENMU ATS project is to create a proof of concept case. Do the algae in fact purify the wastewater? If so what data can we collect to prove this point? The nutrients that the algae will be consuming from the wastewater set the upper limit for biomass production. The daily rate of biomass production should be hyperbolically related to the external nutrient supply rates. We will be focusing on testing organic weight + dry ash (silt) weight, pH, concentration of nutrients/effluent, Total Dissolved Solids (PPM/PPT), Conductivity (µs/Ms), light intensity, light dark cycle, flow of air, and temperature. We will use an UV-vis spectrometer, which will give us an ideal of the optical density of the culture. All these tests and data will then come together to help support our argument that bioremediation could theoretically increase the morphology of the algae for the purposes mentioned above.
