The Ultimate Debris Collector from Imperial Industries combs debris from septic waste so it can be land-applied according to regulations or pretreated for off-loading at a disposal plant. The 85-pound unit attaches to the rear valve of the vacuum truck. Two options on filter combs are available for septic and holding tank service. The septic filter, with 22 teeth, spaced 3/4 inch apart, is designed for removing larger debris, while the holding tank filter has 45 teeth spread 3/8 inch apart. A hinged end cap makes it easy to slide the filters out for cleaning. Debris on the filter can be brushed into a disposal container. 800-558-2945; www.imperialind.com.
