Patent number: 10112852Abstract: Process and apparatus is disclosed for providing a chemical reaction between calcium oxide containing grit particles to produce calcium hydroxide and heat, capturing the heat of hydration and using it to preheat water initially at ambient temperature, to rise to an elevated temperature to increase the amount of lime present in the water to a supersaturated lime suspension level, with the chemical reaction running to completion, followed by cooling. Heat from a water jacket may be used to raise the temperature in the lime slaker. A process and apparatus is also provided for dissolving scale on internal surfaces of a lime slaker, a lime aging tank, grit separation device and piping and dosing sub-systems, by adding acid into the system with rinse water. A pressurized delivery system that is substantially closed to the atmosphere delivers treating doses of slaked lime slurry under sufficient pressure conditions to maintain a relatively constant back pressure, by means of valving.Type: GrantFiled: May 10, 2017Date of Patent: October 30, 2018Assignee: RDP Technologies, Inc.Inventors: Richard W.

Patent number: 9745217Abstract: A lime stabilization system and method is provided in which thickened liquid sludge and lime are separately delivered, under controlled conditions, to a reaction tank and mixed therein to a predetermined pH, controlled via a programmable logic computer. The weight of liquid sludge in the reaction tank is controlled from the computer via load cells that measure the weight of such liquid sludge in the reaction tank. The computer monitors the amount of liquid sludge and lime delivered to the reaction tank, for mixing therein to a desired pH, for a predetermined amount of time, and the resultant mix is discharged from the reaction tank, to a holding tank, for return to the land.Type: GrantFiled: October 8, 2013Date of Patent: August 29, 2017Assignee: RDP TECHNOLOGIES, INC.Inventors: Richard W.

Patent number: 9169147Abstract: A lime stabilization system for treatment of sewage sludge, and method is provided in which dewatered sludge and lime are provided to a mixer. Lime and sludge are mixed to raise the pH during which volatiles are driven off with or without supplemental heat. A forced air draft prevents steam from backing up into the lime supply. The sludge goes to a discharge station via a transfer apparatus, and air containing any dust, odors, steam or ammonia is cleaned via a scrubber. The system is computer-controlled via gravimetric load cells and/or volumetric means. The system includes computer controlled means for dissolving scale resulting from exposure of surfaces to lime, using acid, water or combinations thereof.Type: GrantFiled: October 8, 2013Date of Patent: October 27, 2015Assignee: RDP Technologies, Inc.Inventors: Richard W.
