The Paper industry has a centuries-old history, our ancients used the traditional way to produce paper, and now we use advanced technology to produce more delicate and high-quality paper for all kinds of uses. The tissue, the printing, publication, and the packaging, all need paper.

Behind the pliable and smooth surface of a piece of paper, there are many procedures that need filtration. The starch slurry, which is the primeval form of the paper requiring filtration to improve the quality and eliminate the undissolved starch particles.

The exquisite coated paper, you often find in magazines or the first few pages of a book, is processed by the coating technology. The coating paints also need to be filtered. According to the viscosity level, there are different types of filters suitable for low-viscosity and high-viscosity liquids.

Water is the basic and key resource for many industries, pulp & paper is no exception. Using a filtration system to filter lakes or rivers’ water is a cost-effective way to do water resources management. Additionally, wastewater can be reused and lawful discharged after filtration.

Filtration plays an important role in the pulp & paper industry, infiltration for this field, automative self-cleaning filter is the most suitable and common used filter. Brother Filtration has years of filtration experience and the ability to manufacture filters that fulfill diverse needs, our bag filter, and automative self-cleaning filter are perfect choices for pulp & paper filtration. If you want to know more about applications in this industry, you can read other articles in this section.

Why filtration is so important in the pulp & paper industry?

Throughout the entire process of creating paper, water is used. A ton of paper can be produced with as little as 25,000 gallons of water. Chip washing, pulp washing, and the paper-making process all include the use of water. Additionally, it is utilized for steam production and process cooling.

The water is directly pumped from a river, lake, or storage facility. The industry is looking at solutions to treat, reuse, and recycle process water or white water due to a lack of water and imposed consumption limits.

Pollen, algae, silt, sand, and other suspended solids can contaminate the recycled water and surface water supplies. Additionally, pipe scale and corrosion byproducts have the potential to contaminate all of these water sources. All water used in the pulp washing and paper manufacturing processes must be filtered, regardless of its source.

The water used in the paper-making process (head box), as well as the water used in chip and pulp washing, is pumped and sprayed through nozzles. A crucial step in the production of paper is consistent and effective filtering. In the end, poor filtration results in partially or totally blocked nozzles. Problems with productivity and quality can result from clogged nozzles and/or restricted flow through the nozzles. It is essential to protect the spray nozzle.

For the mill’s profitability as well as the quality of its papers, effective and efficient filtration is essential. Large particles’ passage and deposition can lower the final product’s quality.

The pulp and paper industry is concentrating on techniques to reuse and recycle water as a result of economic and environmental pressures to reduce water consumption and wastewater creation. The pollutants produced during the procedure (pulp production, pulp washing, and paper production) are both organic and inorganic, as well as soluble and insoluble. Filtration, biological systems, and membrane systems are all used to remove these toxins from water.

The kind and degree of treatment needed depends on how the water will be used. Sometimes filtration is all that is needed. Filtration may be used as a pre-treatment in some circumstances or as a post-treatment or polishing step in others. However, filtration will always be necessary to remove suspended particles.

It is crucial to remove the smaller, lighter suspended particles effectively. A positive barrier that can remove both heavy and light particles is what you want in an ideal world. Bag and cartridge filtration is a poor choice because you also want to reduce maintenance and labor.

Brother Filtration helps the pulp & paper industry to get high-quality manufacturing water and better-quality final products. At the same time, expensive production machines can be protected by upstream filtration systems. The maintenance and operation costs can be significantly saved and productivity would keep stable and efficient.
