DESIGN BIOREACTOR TO CONTROL TEMPERATURE AND pH FOR MICROORGANISM CULTURE AT INSTITUTE OF ENVIRONMENTAL SCIENCE, ENGINEERING AND MANAGEMENT; INDUSTRIAL UNIVERSITY OF HO CHI MINH CITY

Abstract

Bioreactor is a culture equipment for capturing biomass or microbial products. In the field of environment, biomass is added to treatment systems to increase the beneficial microbial population in wastewater. The bioreactor is designed on 304 stainless steel with culture capacity from 2 to 10 liters suitable for pilot scale applications. The system uses the method of heating through the wall with PT100 temperature sensor, adjusting the temperature in the range of 30-80OC; the Atlas Scientific pH probe measuring range 0-14; with the UV light for sterilization, the screen to display of setting parameters, the air-flow-control valve. The system can be used for for batch culture or continuous culture through intake and exhaust valves. The system can be controlled manually or by software Bioreactor HC06 installed on a smartphone connected via Bluetooth.
