Technical level and development trend of foreign filter
Since the filter was used in industrial production in Europe at the end of the 18th century, it has been widely used in many fields. With the development of industry and the progress of society, in recent years, it has been urgently required to save energy, effectively use resources and protect the environment. This makes the application of filters even more important. According to a survey of 18 European countries, the growth rate and total output value of their filters and centrifuges in the decade from 1980 to 1989 were 42% and 52.83% USD, respectively. Among the areas where the demand for filter machines has increased rapidly are: coal, alcohol, water and sewage fermentation industry and protein extraction, waste recovery and reuse. However, most of the materials that need to be filtered are difficult to filter, and the amount of treatment varies greatly, so it is urgent to develop high-performance filter equipment to adapt to this situation.
