The substance that requires filtering is fed through a pump to the required pressure (usually 7 to 15 bar). Under this pressure the liquid flows through the cloth which retains any solid particles. This filtrate is collected either at each plate or at the end of the filter. The deposit of material between the plates induces a pressure drop which is compensated by the feed pump. Then this pump must regulate its flow rate according to the amount of pressure in the filter press. It should be noted that some products require a conditioning step prior to filtration by adding reagents that allow their filtration. This process is an integral part of our knowledge and the services we offer through our turnkey dehydration units and after any required testing is done.
A filter press may be equipped with membrane plates. This membrane, which can be distorted by pressurized air or water, allows cake compacting following the filtration phase. In this case, the filtration pressure is usually 8 bar and the compaction ensures cake pressurization at 15 bar. The main benefit of this kind of plate is to increase dehydration performances, to improve productivity and to facilitate cake fall. It also allows to perform cake washing and blowing, if necessary, under optimal conditions.
A plate filter presses is a device used to separate solids from liquids through a filtration process. It is commonly employed in various industrial sectors and production processes to separate solid particles from liquid suspensions.
The filter presses consists of a series of concave plates, a support frame, a network of pipes and channels for mud and water transport, and a range of optional features to optimize its operation.
Thanks to the pressure exerted by a feed pump, the filter press can squeeze the liquid through the filter cloths covering the plates, retaining solid particles inside the chambers, and discharging this dried sludge at the end of the process.
The filtration process in a filter press typically involves the following steps:
Filter presses are used in various sectors, such as wastewater treatment, chemical production, the food and pharmaceutical industries, and many other contexts where it is necessary to separate solids from liquids.There are different types of filter presses, including plate and frame filter presses, chamber filter presses, and membrane filter presses, each with its own characteristics.
Incorporating innovative technologies into fully automatic filter press machines is a hallmark of Matec products. The state-of-the-art design ensures efficiency, speed and performance, with features like high automation and top-quality materials.
