Abstract: The investigation for energy-saving press filter is highly desired due to the technology development trend in solid-liquid separation and the actual energy shortage in today’s global. Based on this consideration, the progress in the theoretical research for press filter is introduced in this paper. For the van press filter, the discussion is emphasized on the comparison in the engineering test results with different pressure and starting point by using experimental data. Thus, the optimum operating conditions would be obtained. Furthermore, the industrial application of import vertical press filter is also discussed based on the test data and application status in output increase and energy saving.
