If target constituent levels of specific sludges and sediments are sufficiently low, one disposal option may be to “de-water/de-oil” the sludge using filter presses or centrifuges. The filter cake may then be landfilled directly, or stabilized and then landfilled. Dewatering technologies are mechanically intensive and are not amenable to highly viscous or tar-like sludges. Wilson works closely with filter press / centrifuge vendors to determine the appropriate equipment configurations and operating points.
Filtrates may be directed to either the conventional wastewater treatment facilities or directly to the on-site slop oil tank, depending on the oil content. If such facilities or disposal options are not readily available, Wilson is expert at determining the best additional treatment or handling methods for your filtrates and filter cake.
