Biological Clogging in Tangshan Sand Columns under Salt Water Intrusion by Sporosarcina pasteurii
Salt Water intrusion is a recurrent phenomenon over the world. This study has purpose to find a new biological way to solve this problem. Sporosarcina Pasteurii, known for its application in biogrouting solutions, was injected into four experimental columns submitted to salt water injection. The bioremediated carbonation reaction was induced by injection of calcium chloride and urea during a three weeks period and results were observed by a new injection of salt water. The increase of salt concentration in the columns after biological treatment shows a slowing down of salt propagation after treatment.
