Abstract

The granular activated carbon (GAC) filter was found to be very effective as a treatment for the removal of herbicide. The Sips isotherms showed the best fit with 6.6% error. Fixed bed column experiments packed with GAC were conducted with different GAC bed heights (5, 10 and 15 cm) and different effluent velocities. The GAC fixed bed column show the model simulation fits reasonably well during the initial period and also with a shallow bed depth (5 cm) with flow rate 4 m/h.  Another set of experiment is GAC and GAC doping Zn with various concentrations to remove herbicide from water. The doped Zn – Tio2 GAC batch experiments can remove MM in term of DOC from 60 to 77% by using different w/v of doped Zn onto TiO2 – GAC. The highest remove of MM 77% by using batch experiment was 0.125% w/v Zn -TiO2.
