Foam and the paper production. Everything you need to know and how we can help.
There are chemicals designed to add foam to the production process and chemicals designed to eliminate it. When it comes to paper production, foam is a nuisance. Excess foam will have a negative impact on the process and equipment. The consequences of foam include slower production rates, higher cost, and inferior or rejected final product paper. Defoamers and antifoams are an absolute necessity to the entire paper making process.
Read on to understand how foam forms during the paper process, the consequences, and the solution.
How is foam formed during the paper process?
Foam is often generated through chemical interactions on the paper machine combined with the rapid motions involved in the paper making process. Chemical interactions with retention aids, fillers, sizing agents, dry strength & wet strength agents can cause foam as a biproducts.
The consequences of foam during the paper process
When paper machines generate foam and entrained air, it adversely affects production rates and paper quality. Defoamers facilitate the process of paper making and help to prevent the following issues:
In addition to the problems mentioned above, slower production rates, higher production costs, inferior or rejected pulp and paper, there are other serious issues caused by foam.
Foam is detrimental to the environment and can increase effluent COD, BOD, and color levels in the effluent. An excess of foam also creates workplace safety hazards and raises production costs.
Some ways foam can increase operational costs:
The solution: Anti-foam agents
Anti-foams, defoamers, deaerators are chemical additives used to eliminate foam and prevent the formation of foam in industrial process liquids. These additives serve the purpose of removing air from the production process.
Using anti-foam agents makes the pulp and paper production process safer, more environmentally friendly, and increases overall production efficiency, all while reducing production costs.
We supply top of the line paper and board deaerators. These highly effective processing aids both remove entrained air and control surface foam at the wet end of paper and paper board systems. Effective deaeration can lead to numerous process benefits; which include increased production, drainage, web strength and clean running of the paper machine. Product selection is typically based on regulatory requirements and application temperature. Our products have been specially developed for paper and paper board systems. These are the same defoamers used by some of the largest paper producers in Europe.
Our product line is specifically designed to work as an effective deaerator in the wet end of the paper & board manufacturing process. Formulated to suit the temperature your machines operate at.
Based on fatty alcohol, fluid water based emulsion is easy to use. It is very persistent, and tends to gives good foam control throughout the system.
Effective deaeration can lead to process benefits. These include increases in production, drainage and web strength. It assists in the clean running of the paper machine and it does not contribute to pitch accumulation.
Our product does not affect sizing or paper strength when used at normal addition levels. It also has a low toxicity.
Additional benefits of our defoamers:
• Excellent deaeration
• Highly dispersible
• Effective at low concentrations
• Increase in fibre matt strength
• Helps with process productivity
Leginston Paper offers defoamers specially formulated for paper production from producers in the United Kingdom, China, and South Korea. Get in touch to find out more.

Some ways foam can increase operational costs:
- Slower production rates.
- Safety issues can arise leading to additional costs.
- Makeup chemical costs are higher.
- Increased deposits.
- Higher energy costs.
- Chemical demands on the paper machines are higher.
