Abstract: A compact, hinged, foldably deployable ramp is provided in a base configuration which includes three evenly radiused sections which connect to a deck member and have a tube, known as a coping, separating the ramp from the deck. In the base configuration, a top section, mid section and lower section each have a pair of ladder structures which share a middle flange. The deck member includes a pair of angled leg members which are designed to provide support throughout the range of engagement of the ramp. Even size and radiusing of the sections enables continued extension of the ramp by adding sections in conjunction with longer support legs for the deck.

Abstract: A process for treating liquid septage and other biosolids having the steps of placing a known amount of liquid septage in a tank, mixing in a sufficient quantity of alkaline material to raise the pH to a desired level, flocculating the septage, storing the pH adjusted septage for a predetermined period of time, thickening the septage, de-watering the septage, and pasteurizing the resultant liquid effluent and de-watered solids cake. The process for treating liquid septage and biosolids disclosed by the current invention meets the Class A vector attractant reduction and pathogen reduction requirements mandated by the U.S. EPA. The end product of septage and other biosolids treated using the process disclosed by the current invention can be sold as fertilizer, and utilized without any additional permits.
