Design of Scalable Biogas Digester for the Developing World

Plastic tubing with inner diameter ½" was connected to a 3/8" brass T-tube using plastic adapters. Radiating from each end of the bifurcation were two plastic tubes each connected to a 3/8" brass ball valve, which also required plastic adapters. From one ball valve, plastic tubing ran into a 5 gallon bucket filled approximately ¾ full with water. ................
