What is the filter?

The press filter is a device that uses a combination of permeable membrane filter elements and pressure to remove fluids from sludge. This process usually involves filling the multi -painted press with sludge and reducing the volume of the inner chamber by pressure. This process forces fluids to leave through a permeable membrane, leaving a semi-mutist cake of solids in the press. The press filter can be used to restore desired solids from transmission suspensions or to remove unwanted solids from water filtration processes. Filter presses are commonly used in the production of food materials and drugs and in chemical and water treatment. For example, production lines of food and pharmaceutical pharmaceutical products must remove valuable powder or granular end products from the water that transmits them by the production process. WNA The other side must remove A ATER treatment plants with undesirable solids to start the process of rehabilitation of waste water. The press filter is one of the methods of filtering that can deal with RYChvět and the amount of sludge connected to these processes. These filters are also some of the most effective and effective systems due to the low number of moving parts and system steps.

The

press filter is generally formed of a series of chambers created by hollow board partitions. The surfaces of the partitions are lined with a filter medium, usually a filter fabric membrane. When printing is open and empty, gaps or chambers between boards are quite large. To start the filter process, all chambers are pumped full porridge. Once this step is completed, the hydraulic or electrically powered ram presses the boards together; It then compresses a cough filled with chambers and presses the mash liquid through the filter membrane and into the interior of the boards. Connected filt channels built into each plate and then drain the liquid.

After completing the compression cycle, the printing is reopened and the plates are graduallydownloaded. The filtered solid cake falls out and collected for later use or disposal and the cycle starts again. After a predetermined number of filter cycles, the plate filters are washed to remove the accumulated sludge. The filter press is suitable for a wide range of mash types including organic and inorganic hydrophilic porridge, inorganic hydrophobic porridge and oil -based. The filter printing process is simple and is not difficult to work; Some conditioning of the filter membrane membrane is necessary to prevent excessive adherence to sludge with certain types of suspensions such as hydrophilic sludge,
