Above ground mesocosm with biofilm growth reactors

Detailed Description

Above ground mesocosm with biofilm growth reactors. Groundwater from the well head is directly transferred to the mesocosm via PTFE tubing into a high flow rate control valve (a) that diverts groundwater into a flow cell containing a water quality measurement meter (b) and a low flow control valve (c). Groundwater passing through the high flow control valve fills the outside chamber (d) while the low flow rate groundwater flows through a series of biofilm growth reactors that contain aquifer core coupons on which the biofilms grow (e) and connected by PTFE tubing (f). Both flow systems discharge through PTFE tubing (g) into flow cells containing water quality measurement meters (b) (from Frontiers in Microbiology, 2020;
