You can see both the experimental setup and part of one of ISEE's bioreactors in this picture. The two tanks, and the rectangluar casing towards the left are apart of the bioreactor. The rectangular case houses a membrane used to introduce more air (or specific gas) into the algal media. What material the membrane is made out of may cause different rates of pH change in the media.

This picture is focused on the experimental setup. Basic media is put into a large flask. A tube then bubbles CO2 into the media and we observe pH change. Samples are collected at various time intervals to be analyzed on the TOC machine.

This particular bioreactor uses flexible, transparent tubing so algae can collect synthesized light provided by a couple of LED panels. The color of the light affects algal growth.

In this setup, industrial wastewater was inoculated with algae and left alone. Light is again provided by an LED panel while the flasks are continuously swirled.
