The first set of experiments was performed without
any dilution of the waste water. 1 g·L−1 of TiO2 was dissolved
in the waste water.
After allowing it to settle
down, the effluent was transferred for the experimental
use. The effluent was re-circulated through the reactor
system for a period of 5 hours starting from 09:30 AM.
The sample was taken after every 1 hour for parameter
analysis. The second and third sets of experiments were
performed with 25% dilution and 50% dilution respectively.
