The WWS Mark IV dewatering/screening unit from Old Line Environmental helps remove rags, wipes, grease and debris from septage receiving stations, wet well/pump station and vacuum waste, as well as digester debris from thickened biosolids. The unit can help reduce pump and sewer line maintenance costs and saves operational labor and cumbersome repairs. It is a complete skid-mounted unit that allows for both permanent and mobile applications. It is operator friendly with Allen Bradley touch-screen controls and automated features. All dewatered/screened debris passes paint filter testing and can be conveyed into conventional dumpsters for landfill disposal. 410/241-1654; www.oldlineenv.com
