Investigation of Turbid Water Characteristics and Its Control at a Slag Landfill Located by the Seashore

Abstract

This study was conducted to evaluate the possible cause of the turbidity leaks around the K steel slag landfill located in the republic of Korea and suggest a future counter-plan to mitigate the currents problems of leaching turbid water and control by monitoring the behaviour of the pollutants based on data taken from field surveys and laboratory experiments. The distribution of the turbidity source and possible discharge points were examined through exploration of electric specific resistance and excavation, which observed the behaviour of pollutants and movement closely related to geological characteristics such as base soils and rock constituent. The function of pollutant removal for the existing filtration system and facilities was tested in laboratory scale equipment with brand-new media and excavated media from the field. A more than 98 % removal efficiency of turbidity for both media was achieved with the serial multi-media filtration system. The cutoff function of the bentonite mat was lowered compared to that of the new one, which might be due to the reaction of salt in seawater.
