Prospects for the application of filter presses in the paper industry

In the “double carbon” target and environmental protection policy is increasingly stringent, the paper industry to the green, sustainable direction of the transformation needs more and more urgent. Filter press as a paper process to achieve efficient separation of solid-liquid key equipment, is ushering in a very broad application prospects.

From the environmental protection level, the paper industry wastewater emissions are huge, if the direct discharge without effective treatment, will cause serious pollution to the environment. Filter press can efficiently handle paper wastewater, through the precise separation of fibers, fillers, chemicals and other solids, greatly reducing the degree of pollution of wastewater, help enterprises to meet the increasingly stringent environmental emission standards. Like the state of the paper industry water pollutant emissions set clear and strict standards, requiring enterprises to deep treatment of wastewater, which undoubtedly provides a solid policy support for the application of filter presses and a broad market space. In some places, the government is through special funding support, green factory certification and other means to incentivize paper enterprises to actively use advanced environmental protection equipment, filter press is one of the key equipment to promote.

In terms of resource recycling, the papermaking process will produce a large number of recyclable resources, such as fiber, white water and so on. Filter press can be wastewater fiber recovery, these recycled fibers can be reused in paper production, effectively reducing the dependence on virgin fiber, saving raw material costs. At the same time, the recovered white water can be reused in the production process after treatment, realizing the recycling of water resources, in line with the concept of sustainable development of the paper industry. For example, some papermaking enterprises with the help of advanced filter press equipment, each year successfully recovered a large number of fibers and white water, not only reduces the production costs, but also reduces the resources required for the environment, realizing a win-win situation for both economic and environmental benefits.

Technological innovation has also injected a strong impetus for the application of filter presses in the paper industry. Nowadays, intelligentization and automation have become the new trend in the development of filter press. Through the introduction of advanced sensors, intelligent control systems, filter presses can realize automated operation, real-time adjustment of working parameters according to production demand, improve filtration efficiency and quality. Moreover, the operating status of the equipment can be monitored in real time and early warning, facilitating timely maintenance and reducing the equipment failure rate. Some high-end filter presses also use new materials and processes to further enhance the durability and filtration performance of the equipment. With the deep penetration of intelligent manufacturing technology in the paper industry, the filter press will be deeply integrated with other production equipment to build a more efficient and intelligent production system, and promote the paper industry to high-end, intelligent.

As the market demand for green, low-carbon products continues to grow, paper companies in order to enhance their competitiveness, will inevitably increase investment in environmental protection and resource recovery, filter press as a key equipment to achieve this goal, its market demand is expected to rise steadily. Globally, as countries pay more attention to environmental protection, the environmental standards for imported paper are becoming increasingly stringent. This has prompted domestic paper enterprises to improve their environmental protection level to meet the needs of the international market, thus bringing more opportunities for the application of filter presses.
