CATION EXCHANGE CAPACITY (CEC) OF CLAY KUTAI AND ESCHERICHIA COLI REDUCTION

Abstract

Objective: Increasing frequency of flood and un-treatment domestic water waste potential risk factors contamination of pathogen microorganism on the drainage in the city area. In the study would be explored the effective clay Kutai for Escherichia coli/E. Coli reducing Methods: In this research was used Most Probable Number (MPN) was for Escherichia coli/E. Coli diagnosing, with the third stage of the technique is the presumptive test, confirmed test, and completed test on control formula and experimental formulas to add clay Kutai and white cement in the samples. . Results: The highest effective formula was clay Kutai with white cement addition, the composition of the formula is 3:1 (7.5 g clay Kutai and 2.5 g white cement. The CEC (Capacity exchange of cations ) 16.95 Meq/100gr and clay content 55.9%, the formula has the high reduction of E. coli, in control 9,2 X 104 E. coli dan 150 E. coli after the experiment, with the degree of effectively 99.82%. Conclusion:Using Clay Kutai with high clay content and high CEC for reducing E. coli in water waste with to adding white cement in the formula have increased bacteria reduction
