ABSTRACT NEXT GENERATION INDUSTRIAL WASTEWATER TREATMENT FOR STEEL INDUSTRY BRIEF PROBABLE SOLUTION: Our solution focuses on treating wastewater for steel industry by employing biological process and applying the use of various microorganisms for absorbing various constituents present in wastewater. These microorganisms consists of Chlorella vulgaris(Green Algae),Order laminariales(brown Algae), Synedra(yellow brown Algae), and Azosprillium brasilense(bacteria). Our idea is to use the symbiotic relation between algae and bacteria in an co-immobilized culture that would provide better platform for algal function by using carbon negative, light and controlled conditions ,harvesting…show more content…
Catalyst for the reaction is Na ethanoate which is transformed to glycerol and 3-methyl ester which is the fuel. STEP 3: The left biomass goes for pyrolysis process at a temperature range of 500-600 degree Celsius in the absence of air and then condensed by temperature change. The process then uses algae in its original state to create biofuel. After the process occurs only product is gas, char and fuel. -Gas can be reused as a resource somewhere else. - char can be used as an organic fertilizer or fuel. 2. ALTERNATE USE OF BEADS: - The beads containing bacteria and algae is dehydrated and can be directly used as a soil fertilizer which is a value added product. - This is highly economical. 1(B): ENERGY PRODUCTION FROM Chlorella vulgaris WHEN NOT IN THE FORM OF BEADS: STEP 1: After algae is separated i.e. biomass harvesting is done by flocculation process, we pass it through gravity classifier, biomass settles at bottom, water in between, and oil at top. STEP 2: This oil is used for the production of biofuel after transesterification reaction as explained in 1(A)-1 step 2. STEP 3: The left biomass is used the sameway as explained in 1(A)-1 step
