Latest Patents
Glenn E. Petrie holds a patent for a process aimed at dewatering biological sludge. The patent describes an improved method that involves several key steps. First, biological sludge is heated to a temperature ranging from about 90 to about 150 degrees Celsius, corresponding to a pressure of about 0 to about 55 psig, and retained at that temperature for less than about 15 minutes. Next, the heated sludge is centrifuged to separate the solids from the liquid. The isolated solids are then chemically conditioned before being dewatered to produce a high solids biological sludge. This process results in a high solids cake that can be utilized in various ways, including landfill disposal, incineration, or as fertilizer.
