Solid Residuals Management at Centralized Vehicle Wash Facilities

摘要

Solid residuals produced at U.S. Army centralized vehicle wash facilities (CVWF)present problems in managing primary and secondary sedimentation basins. Fine sediments are difficult to dewater and delay routine sedimentation-basin cleaning for extended periods. The presence of contaminants in some sediments necessitates development of procedures for sampling, testing, evaluation, treatment, and disposal. A literature search was conducted to identify appropriate dewatering and treatment technologies for solid residuals characteristics of these facilities. Technologies utilized in the management of contaminated and uncontaminated dredged material were reviewed for applicability to CVWF sediments. The principal focus of this study included effective materials handling methods, improved dewatering methods, and treatment and disposal alternatives. A review of operational practices and problems and recommendations for operational and facility modifications were made. (MM).
