Filter is a kind of common equipment used to separate solid and liquid, widely used in pharmaceutical, food, chemical and other industries. In recent years, with the increasing severity of environmental pollution, the market demand for filters is gradually increasing, the filter effect requirements are also gradually improving. Domestic filter equipment manufacturers in this context, to strengthen technological innovation, has basically met the needs of the market, but compared with foreign filter technology, is far from enough. In the pharmaceutical industry, filter is the use of porous filter media to complete solid, liquid separation equipment. With the development of the times, different types and functions of filter devices have emerged in the market, but there are still many bottlenecks in the development. For example, the development prospect of high efficiency filters in the domestic market is very considerable, but in terms of scope, there is still a certain gap between China's high efficiency filter equipment and the international level, its filtering effect, structure and design need to be improved and innovated. On the whole, China's filter press machinery manufacturing industry is still at the stage of development, and there is a great demand in the fields of chemical industry, petrochemical industry, food industry, pharmaceutical industry, military industry manufacturing, etc. , most rely on foreign imports, domestic filter equipment market is still to be "deep-tillage excavation. ". Industry experts said that the lack of domestic equipment market competitive advantage is mainly due to the filter technology defects, filter effect, efficiency is difficult to meet the requirements. In addition, the filtration equipment enterprises in our country are mainly self-employed, the market is small, scattered, disorderly, lack of efficient management system, limited resources, because they can not "make a mark" on the market. Blind production will only lead to market chaos, affect the overall development of the filtration industry. Therefore, in the current international filter market competition is so fierce, China's filter industry enterprises can be engaged in the following aspects of efforts: first, the technical level, in a technical position; Second, efficiency advantage, improve the use of equipment efficiency, to avoid repeated construction; third, Management Advantage, a relatively simple production and operation system to establish a set of efficient management system. As a result, small and medium-sized enterprises focus on their limited resources, specializing in their own professional areas, professional products, thus winning in the market competition. With the rapid development of science and technology, people have a new pursuit for the filter equipment, which will also develop new areas for the filter, expanding the filter development space. In recent years, China has been advocating the green environmental protection industry, so filter equipment manufacturers from the point of view of energy conservation and environmental protection, improve the filter equipment, continue to promote its development, make it become a new type of equipment and development highlights. With the increasingly serious environmental pollution and the strengthening of people's environmental awareness, the use of filters is becoming more and more widespread, not only in all sectors of the industry, but also deeply into people's lives, domestic water quality, drinking water quality, air quality and so on can not be separated from the filter, especially the filter efficiency is more and more high. How to occupy a place in the fierce market competition has become the focus of the filter industry, filter in China's pharmaceutical industry has a very important position, play a very important role. With the continuous development of science and technology, filter equipment manufacturers only seize the opportunity to forge ahead, in order to better meet market demand, faster replacement of foreign equipment products.
