Local Soil

Soil strata abilities to drain water at high volume is the essential properties in RBF (Riverbank Filtration). An artificial barrier (AB) is a man-made vertical barrier to pre-treat water abstraction intake. It is a mixture of sand (local soil), granular activated carbon (GAC) and zeolite. In this work, AB was made to enhance the flow of groundwater as well as water quality. The soil analysis of borehole near Kerian River featured clay, sandy clay loam and sandy loam. In the study, a local soil was mixed Granular Activated Carbon (GAC) at 9:1 (10% GAC), 7:3 and 1:1 ratios. The immediate results are the permeability increased with the percentage of GAC. Further, similar tests were conducted with a mixture of local soil, GAC and zeolite in ratio of 5:2:3 in a laboratory scale physical model. The removal of turbidity and iron in a local soil (without GAC and zeolite) in the range of 59% - 88% and 74% - 87%, respectively. However, a better removal capacity of turbidity and iron were found in the mixture of local soil, GAC and zeolite up to 76% - 98.8% and 73% -92% removals respectively. In sum, the initial study indicate that the mixture of local soil, GAC and zeolite with a specific ratio could provide a pre-treatment of turbidity and iron removal in RBF abstraction.

Iron and manganese oxides/granular activated carbon composite (GACFM) was prepared via a chemical coprecipitation route, followed by a heat treatment at elevated temperature. The as–prepared GACFM was characterized by X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The main iron and manganese oxides actually present in the composites were mainly composed of Fe3O4 ,Mn3O4 and (FeO)x(MnO)1-x. The adsorption and catalytic properties of GACFM and some conditions effects such as H2O2, pH , temperature and CO32- were studied for the removal of 2,4,6-trichlorophenol (TCP) from aqueous medium. The adsorption of TCP on GACFM obeyed the Freundlich isotherms. When the initial concentration of H2O2 was 0.4mg/L , 5mg/L TCP removal rate was maximum on the GACFM. The treatment of TCP could be carried out at initial pH under 7.0. CO32- can scavenge •OH in solution and decreased TCP removal. In the whole, GACFM was satisfactory absorbent and catalyst for the removal of chlorophenol from water.

In Harelbeke a Water Treatment Plant with a capacity of 15,000 m3/day, using Schelde river water has been in operation since April 1995. The treatment process comprises nitrification, dephosphatation by direct filtration, storage into a reservoir, direct filtration, granular activated carbon filtration and disinfection. The design of the three-layer direct filters was based on pilot experiments. The performance of the plant during the five years of operation is discussed. It was found that the removal of atrazin by activated carbon depends on the water temperature.
