In paper & pulp industry, the water is key to the production. Manufacturers need large quantities of water to make pulp. Water is employed as a medium to transport pulp, convey and absorb heat, and remove impurities from the finished product since it is the lifeblood of the paper-making process.

With the development of the environment, manufacturers need to pay a lot for water resources. In order to achieve its goals in terms of the economy, society, safety, and the environment, the paper industry must balance its water use.

For one ton of paper, around 7800 gallons of water are needed. One of the largest industrial uses of freshwater is the paper sector. Many of them begin to adopt complex water resources management.

Paper manufacturers need stable and abundant water resources at lower prices, so they choose rivers or lakes as the papermaking water. However, water from these resources can not be used directly for manufacturing. Also, after the production of paper, the left water should be filtered before discharge.

Why do we need filtration for papermaking water?


Compared with expensive water resource, manufacturers prefer to use lakes or rivers water. Those resources contain various impurities and contaminants such as silt, algae, and dust.

The filtration system can effectively remove and eliminate these impurities to protect the manufacturing machines. Because liquids with those impurities can clog and damage the equipment while passing through it.

Though we need a filtration system for these water resources, the total cost is much more affordable than the expensive high-quality water. A suitable filtration system can promote the quality of water making it achieve the used standard. With the help of filtration, the cost can be decreased.

Filtration for papermaking water

Considering the characteristic of the pulp & paper industry, an efficient filter should be selected. Generally, the automative self-cleaning filter with a filter rating from 50μm to 500μm is applied to this application.

Because the pulp & paper industry consumes a large amount of water, filtration without interruption is needful. Compared with a conventional filtration system, automative self-cleaning filter can be a better choice.

Water used in papermaking can be reused after the effective treatment. We can place automative self-cleaning filter in the end and beginning of the production line. Brother Filtration’s automative self-cleaning filter has a compact design, which requires a small installation footprint and doesn’t affect the performance of the original equipment.

At the beginning of the production, we can obtain high-quality pure water for the pulp and downstream production. Impurities and debris in the natural water resource can be removed to assure the quality of the final paper products and the protection of the manufacturing equipment.

At the end of the production line, we can also employ a self-cleaning filter, which is also essential. The used water can be reused with appropriate treatment and purifying. In addition, the discharge of the wastewater should abide by local laws and regulations. Contaminants and impurities should be filtered out before emission.


As it is in many other industries, water is also crucial in papermaking. No matter before or after production, water should be treated. By filtering water from lakes or rivers, production costs can be saved.

And wastewater can be transformed into recycle resource or reached emission standards. Brother Filtration automative self-cleaning filter is suitable for papermaking water filtration.
