Development and In-situ Application of Asbestos Removal Equipment for Asbestos-contaminated Soils

Chang Koo Park, Jeong Wook Kim, Yo Seb Kwon, Myung Chae Jung , Jin-Soo Lee and Kwan In Park

Abstract : The objective of this study is to develop removal equipments of fibrous materials including friable asbestos in soils. Asbestos removal equipment, was invented using artifical friability and its optimun working conditions were examined. Then, the suggested working conditions such as 200 rpm of rotation for brush, 3 m/s of inhale velocity and 0.1 m/s of moving equipment velocity were applied in the field. Soil samples were collected from various places including playground of elementary school, orchard and farmland and then analyzed with 20 retuning times in order to measure asbestos concentration before and after remediation. The collected asbestos from the soils by the developed equipment were 18.414 f/cc, 12.668 f/cc and 104.310 f/cc for playground, orchard and farmland respectively. Asbestos contents in soils were decreased from 1% to 0.5% with 50% removal effectiveness before and after soil remediation using the developed equipment. Additional facilities reducing soil water contents and disturbing the contaminated soil are suggested to improve the asbestos removal efficiency of the developed equipment.

Key words : Asbestos removal equipment, Fibrous materials, Soil remediation, Friable asbestos
