only a small head pressure
of 1–2 bar was required. Pressure was only applied immediately
before treatment to prevent alteration in dissolved O2 levels. Water
(30 L) was passed through the reactor without illumination to
determine system and dark adsorption with samples (triplicate
200 mL) collected directly from the outflow. To evaluate the photocatalytic removal of the 2-MIB and GSM, three 30 L batches were
passed through the reactor at 2 L min1 under constant illumination. Samples (200 mL) were collected in triplicate as each of the
three batches passed through the reactor
