Foam is often generated through chemical interactions on the paper machine combined with the rapid motions involved in the paper making process. Some of these interactions may involve chemistries from:

• Retention aids

• Fillers

• Sizing

• Fines

• Dry strength

• Wet strength

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:

• Bacteria buildup

• Poor sheet formation

• Drainage issues

• Pump cavitation

• Poor housekeeping

• Safety problems

• Pulp consistency

Slower production rates and inferior or rejected pulp and paper aren’t the only problems caused by foam. For both pulping and papermaking, other foaming issues can create costly outcomes. 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. A few ways foam can increase operational costs:

• Slower production rates

• Increased deposits

• Higher energy costs

• Increasing makeup chemical costs

• Increasing chemical demands on the paper machines

Using defoamers makes the pulp and paper production process safer, more environmentally friendly, and increases overall production efficiency, all while reducing production costs.
