<p>A pressure-filter apparatus includes at least one filtration chamber coupled with a source of slurry. The filtration chamber is also coupled with a source of fluid at an elevated pressure, which may be arranged in series or in parallel with a source of wash fluid. The pressure-filter apparatus may also include a source of fluid at a conventional pressure. The source of fluid at elevated pressure has a limited volume for initially treating the slurry within the chamber. The source of fluid at conventional pressure has a substantially unlimited volume for completing the treating of slurry within the chamber. The relative volume capacity of the two fluid sources provides an improved efficiency in the treatment of the slurry and the overall efficiency of the apparatus by limiting the time and capacity of accumulation of elevated pressure fluid while using the conventional pressure for extended treatment of the slurry within the chamber.</p> |
