A filter press is a machine that is used to separate solids from liquids. This kind of press was invented in 1853 as a manually operated machine that was developed to obtain seed oil. It wasn't until 1959 when the first automatic press was designed and adopted a wider range of applications. These presses are used for everything from blood purification to mineral mining. They are designed to filter very fine minerals and debris which is what makes them viable for a myriad of different applications. These presses are widely used for commercial operations such as maple syrup development. There are three types of filter presses available on the market: Plate and Frame Options A pair of rails support a series of different plates in a given press, which alternate with one another to separate the liquid from the solid materials that are put into the machine. Automatic Options This is simply an automatic version of Plate and Frame models, although automatic machines tend to use larger plates for filtering than the other varieties. Recessed Options Recessed presses can hold up to 80 plates at a time, so they can get big jobs done pretty quickly. Filter plates are large, usually square pieces of metal that work together within these machines to help separate and thoroughly clean whatever liquids, materials, or slurries are put in. They are not permanent fixtures- they need to be replaced on a regular basis to keep the machines working properly. The most popular options are high-density polypropylene plates because they can be configured in several ways: * Gasketed * Non-Gasketed * Membrane * Plate and Frame The types of plates that are used depend on the kind of machine they will be installed in, and the type of slurry or liquid that needs to be cleaned. There are also nylon and aluminum filter plates available. Presses and Waste Toxic chemicals, pathogens, and many other types of waste can also be managed with the help of these presses. They are usually used with a series of other sanitation equipment to help prevent health risks within the general population. Presses can only be used in areas that are sanctioned by local authorities when used to handle waste because of all the risks involved. Buying Presses and Plates Before choosing which press and filter plates to use, you will want to determine the kind of output you are looking to create with your new machine. It is always a good idea to overestimate your needs so that your machine can grow with you as your business grow. There are many sizes available, so the size you choose will determine the type and size plates you will need to invest in. You will want to do some research on the plates to figure out which will give you the most bang for your buck in the long run, seeing as how you'll need to replace them from time to time.
