INCREASED PERFORMANCE STANDARDS IN SCREENINGS WASHING, DEWATERING, AND VOLUME REDUCTION

The headworks are often the most unpleasant aspect of any wastewater treatment process. Here, coarse mechanical bar screens or fine screens remove tremendous quantities of wet, putrescible organic material. This removal process is not only unpleasant, but can be hazardous in exposing treatment personnel to wastewater borne pathogens and other health risks. In addition, transportation and handling cost are increased with the additional weight of unwanted water and organic material in the disposed screenings. One solution to this problem has been the use of washer compactors on the discharge end of these screening devices. However, traditional washer compactors are typically limited in their ability to effectively remove fecal material from raw wastewater screenings. This usually results in unpleasant smelling discharged solids that are inefficiently compacted.
