A study on the potential of riverbank filtration for the removal of color,iron,turbidity and E.Coli in Sungai Perak,Kota Lama Kiri,Kuala Kangsar,Perak,Malaysia

Riverbank filtration technology in securing water resource is still new to some developing countries such as malaysia. this research has been carried out at kota lama kiri in the kuala kangsar,perak,malaysia to study the removal on the turbidity,iron,color,and e.coli by riverbank filtration. characteristics of soil samples from pumping well (pw) was investigated. the soil samples were collected during the development and construction process of the pw. the water quality analyses were performed on site during the pumping test program. the soil samples collected were transported to the geotechnical engineering laboratory,universiti sains malaysia where sieve analyses and permeability test were performed with reference to bs 1377: part 2:1990. results of sieve analyses shows that the value of cu (coefficient of uniformity) for the pw was found to be within the range of 2.40 to 3.75 mm while the value of cc (coefficient of gradation) lies in the range of 0.06-0.35 mm. the anova one way test for soil strata of the pw was performed using minitab statistical packages and the results indicate that the p-value was 0.996. it was found that there were no significance differences between the mean size of soil samples from different depths within the pw. the hydraulic conductivity,k value for pw ranges between 0.10-5.65 cm/s. removal of turbidity,color,iron,and e.coli were 98.78%,73.56%,and 87.93%,respectively. in this study,the highest removal efficiency of e.coli was found to be 100%.the overall well production from the pumping test was found 112.10 m3/hr. © 2015 penerbit utm press. all rights reserved.
