Abstract
A method and apparatus are provided for removing liquids from biological waste by the employment of centrifugal force to separate the liquid from the biological waste particulate and into a container separate from a biological waste container, permitting the dried biological waste and removed liquid to be separately and conveniently disposed of. Preferably, a rotatable drum can be rotatably supported within an outer liquid-tight drum, and a disposable porous container, such as a bag made of porous material, can be placed within the rotatable foraminous drum. Biological waste can be placed within the porous, disposable container within the rotatable drum, and the rotatable drum can be rotated at a rate of rotation sufficient to substantially transfer unabsorbed liquid from the biological waste through the disposable porous container and the openings in the foraminous inner drum to the outer liquid-tight collection drum. Solid biological waste may then be disposed of by removing the disposable porous container from the rotatable drum with the solid biological waste therein, avoiding by closure of disposable porous container, exposure of handling personnel to the solid biological waste. The collected liquids may be separately disposed of by pumping them into a sanitary sewer. If it is desired, additional liquid, such as a microbial decontaminating agent, may be added within the porous disposable bag as it is being rotated.
