How Sludge Filter Presses Work?
The basic components and mechanics of a sludge filter pressing are: Filter plates – These consist of a filter cloth or membrane sandwiched between rigid plates. The filter media separates solids from liquids under pressure. Slurry feed – The slurry or sludge to be dewatered is fed into the space between the plates. Hydraulic frame – The plates are secured in a frame that can be tightened hydraulically. As pressure is applied, water passes through the filter media but solids are captured. Filtrate discharge – The filtered water or filtrate drains out of the end of the filter press. Cake discharge – The dewatered solids or filter cake builds up between the plates and is discharged when the press is opened. Types of Filter Plates There are two main types of filter plates in sludge filter presses: Frame plates – Provide structure but have no filter media. They separate the active filter plates. Filter plates – Contain the filter cloth or membrane to separate solids and liquids. Commo...
