Apparatus and process for separating components of a treatment mixture from a waste treatment system comprises feeding the treatment mixture to an endless filtering belt. The filtering belt (111) has a mesh size selected to permit liquid components of the mixture to filter down through the belt while retaining particulate components thereon. The belt (111) is moved by a drive system generally in a circuit between upstream and downstream ends of the apparatus as liquid components are separated from the mixture by filtering through the filtering belt (111). Unfiltered mixture is passed beneath a press (211, 231) disposed in opposed relation with the belt generally between the upstream and downstream ends of the apparatus. The press is capable of applying a squeezing pressure against the mixture to squeeze the mixture between the press (211, 231) and the filtering belt (111) to separate water and liquified fatty components from the mixture for filtering through the belt. The press is adapted for movement toward and away from the filtering belt to allow the mixture to pass downstream of the press substantially without particulate components of the mixture being mashed into and entrained in the filtering belt by the squeezing pressure of the press. |
