Toward on-line measurement of algal properties Conference Paper uri icon


  • Algae is a potential source of large amounts of lipids for conversion to hydrocarbon fuels. Industrial-scale algae production requires process control, which further requires sensors to measure critical algal properties. One of the principal properties that needs to be measured in algae production is optical density. In this work an opto-electronic sensor was developed for the initial purpose of measuring optical density in real time in situ. A prototype was built and proved to be very accurate, with an R2 value greater than 0.98 when compared to laboratory OD measurements. The prototype also worked very well in a field test in which the range of OD values measured was limited.
