TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The microalgae is Chlorella and the treated water has a salinity level of up to 30000 parts per million (ppm), and the microalgae is resident in the bioreactor for 1 to 1.5 weeks; or the microalgae is Spirulina and the treated water has a salinity level of up to 15000 ppm, and the microalgae is resident in the bioreactor for about one week. Preferred System: The system includes several bioreactors housing different species of microalgae, each bioreactor being in fluid communication with the treatment unit, where the treatment unit provides several outlet streams, each independently having a predetermined salinity level predicated by the specie of microalgae housed in the bioreactor to which each respective outlet stream is reported. The bioreactor includes a modular bioreactor in combination with an enclosed pond. The treatment unit includes at least one electrolysis unit and/or at least one capacitive deionization unit. The system includes an external engine for pumping the saline water feed and/or the treated water within the system; and a carbon dioxide (CO2) capture unit for capturing CO2 produced by the external engine, where the CO2 capture unit is in fluid communication with the treated water and/or each bioreactor is such that CO2 produced by the external engine can be introduced to the treated water and/or each bioreactor.    TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Process: The treatment of the water includes electrodialysis of the water to provide predetermined salinity level. In the process several bioreactors are provided, each housing a different species of microalgae, and the treatment of the water includes electrodialysis or capacitive deionization to provide several outlet streams, each independently having a predetermined salinity level predicated by the specie of microalgae housed in the bioreactor to which each respective outlet stream is reported. The different species of microalgae housed in the bioreactors produce different fuel products. A nutrient containing waste water, such as from municipal waste, is introduced to the bioreactor to provide additional nutrient to the microalgae. Carbon dioxide is injected into the treated water that is directed into the bioreactor, and/or is injected directly into the bioreactor. EXAMPLE - No suitable example given.
