What is the difference between the open flow and the underflow of the filter press drainage

Everyone who buys filter press equipment will see a set of letters \"A\" and \"M\" on the nameplate, which means that the way the filter press drains water is different. \"A\" represents the undercurrent Drainage, and \"M\" represents open-flow drainage. They are the pinyin initials of \"dark\" and \"ming\" respectively.


What is the difference between open current and undercurrent in actual operation? Sudong Chemical will answer this question for you next:


When the open flow filter press is filtered, the filtered liquid will inevitably be contaminated or mixed with impurities in the harsh environment of the filter press. Therefore, the underflow filter press is used to maintain the results of the work done in front of the filter press. A closed environment to ensure that the filtrate is not contaminated. Therefore, open flow filter presses can only be used in occupations that require solids after filtration of solid-liquid mixtures, such as metallurgy, ore, etc., while underflow filter presses are used in occupations that require high filtered liquids, such as medicine. , Biology, etc. This is the difference between the open current and the undercurrent of the filter press.


The usual filter presses use open flow drainage. In such a filter press, when the filtrate passes through the filter chamber, it directly passes through the drainage pipe under the filter plate and is directly discharged outside the equipment through the faucet. The undercurrent filter press equipment is to plan a system for collecting filtrate under the faucet, and collect the filtered plan through the pipeline. The conventional method is to connect the faucet under the filter plate of the filter press to a sealed hose, and a larger pipeline connected to all hoses is planned under the hose, so that the liquid can be reconstituted. Maintain it. The underflow filter press is usually suitable for toxic, odorous, volatile and flammable materials.


Through the above introduction, the difference between the open current and the undercurrent is clear, and everyone should plan reasonably how to deal with the filtered liquid. After all, this is closely related to the next process. According to the different materials to be processed, the open current and the undercurrent have their own advantages and disadvantages. I hope everyone is correct. select.
