Key Factors When Selecting A Filter Press

By Virginia Peterson


Filter presses are widely used in different applications and industries around the world for separating liquids and solids. Industries uses this equipment includes mineral processing, chemical, pharmaceuticals, aggregate processing, water and waste treatments, food and beverage and many other things. Due to its effectiveness, industries have effectively managed the materials waste separations. There are many factors to consider when choosing a Filter Press so individuals will have to conduct research in order top find the right one for their applications.

Filtrate water discharge option. The liquid when remove during the dewatering on the equipment will through filter cloths that was mounted on plate surfaces then exit through internal channels or ports. For those that has closed filtrate discharge, the liquid will pass from the surfaces of the plates to small channels with many corners.

The style of frames and plates where being plagued by many problems when the time comes to remove the dewatered solid materials from frames. Though the frame design and plate are still widely used in various applications and industries, the new ones employ membrane or recessed designs which is more popular. Individuals must determine between recessed and membrane presses.

Manual cleaning with water is the easiest way to extend the lifespan of cloths. Hoses with medium volumes and pressure can be used to remove any buildup on the surfaces especially in areas such as stay boss and sealing. A fully automated system is much more effective than manual labor. These systems use high pressures of showers that will automatically position themselves on each plate and be programmed to efficiently clean the cloth at different intervals of cycles or times.

In side beam types, it has an opening mechanism which is accomplished by a stroke of hydraulic compression cylinder or a separate opening mechanism which can be opened by a single movement. The plate is being attached with mechanical linkage or short chains which will allow multiple plates that will be opened in one movement.

If presses are designed with feeding from both ends, there is a possibility to finish a core blow. After the filtration stage is over and the feed pumped has already stopped, wet slurries will remain at the core holes on the plates. The next sequence would be a core blow to complete the removal of remaining slurries before the plates would be opened.

Another one common pump for filter presses is positive displacement pump. The pump machine used will control the maximum pressure and the flow of slurry which is fed to the equipment. Higher flows and pressures will increase the capacities of the equipment.

Researching will determine the right equipment for your needs. Even though there are many choices to choose from, the best way to know the best filter presses is by spending some time in doing research. Asking some friends and family that has done the process in the past can share their opinions about the matter.

Budgeting is another aspect that needs to be considered carefully. This equipment does not come in cheap especially if the materials are high quality. To be precise on the budget, make sure to take the time to make a few calls and ask for estimation to prepare your finances before buying one.
