TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The diazotroph used in secondary carbon source reactor is Azotobacter spp. chorochome. The solution containing a microorganism is an Azotobacter medium with perlite used as a hydrophilic adjuvant.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The sequential batch reactor comprises: a housing with an inlet and outlet present on a top for adding an influent and withdrawing an effluent; a pump connected to the inlet and the outlet for controlling a feed of the influent and a removal of the effluent; an air diffuser positioned at a bottom for diffusing an air inside; an air pump connected to the air diffuser for pumping the air to the air diffuser; a recirculation inlet and outlet provided at a side wall surface; a recirculation pump connected to the recirculation inlet and outlet for recirculating the influents periodically; two timers for controlling a working of the recirculation pump and a working of the air pump respectively; a temperature controller for regulating a temperature within the sequential batch reactor; and a sample outlet for collecting a sample. The secondary carbon source reactor comprises: a metallic cubicle box arranged at a desired height level from a ground level; an inlet and an outlet present on a top of the metallic cubicle box for an addition and a removal of a material; a fine wood spontaneous media arranged inside the metallic cubicle box for providing a medium for a reaction between the diazotrophs and carbon dioxide gas; a storage tank positioned at the bottom of the metallic cubicle box for storing a solution containing diazotrophs; a recirculation pump for recirculating the solution containing diazotrophs from the storage tank to the fine wood spontaneous media via many tube during the pre-treatment process of diazotrophs; a timer for controlling a pumping time of the solution to the fine wood spontaneous media; a carbon dioxide generator for producing carbon dioxide gas during the pre-treatment process of diazotrophs; a carbon dioxide gas inlet for an input of the produced carbon dioxide gas inside the secondary carbon source reactor; a water key to manage an input of water into the storage tank and the secondary carbon source reactor for washing the secondary carbon source reactor after each use; a temperature controller for controlling a temperature inside the secondary carbon source reactor; and a sample outlet for collecting a sample. The carbon dioxide generator comprises a firebox and a thermocouple. The polymer production reactor comprises: a chamber having an inlet on a top for adding materials; an air diffuser positioned at a bottom for supplying air inside for aeration; an air pump connected to the air diffuser for pumping an air to the air diffuser; a temperature controller for regulating a temperature inside the polymer production reactor; a pH controller for adjusting the pH of the materials; and an outlet for collecting a final product. The materials comprises an acclimated activated sludge taken from the sequential batch reactor and pretreated diazotrophs collected from the secondary carbon source reactor.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The carbon dioxide is a secondary source of carbon with a concentration of 10%.
