Paper Mills

Fouling and scaling occurs in paper mills at various stages and equipment throughout the production process. While fouling in paper mills may not involve the same scale-forming minerals or scaling mechanisms seen in other industries, the accumulation of fibers, fillers, coatings, and contaminants can still lead to fouling-related challenges. Regular cleaning, maintenance, and appropriate filtration systems are crucial for managing fouling in paper mills to maintain operational efficiency and ensure product quality.

Heat Exchangers

Paper mills use heat exchangers for processes such as heating, drying, and cooling. Fouling can occur on the heat exchange surfaces due to the accumulation of fibers, fillers, coating additives, and other suspended solids present in the process water. Scaling can also occur when dissolved minerals, such as calcium carbonate or calcium sulfate, precipitate and deposit on the heat exchange surfaces. Fouling and scaling in heat exchangers reduce heat transfer efficiency, increase energy consumption, and require regular additional cleaning and maintenance.

Piping and Equipment

Fouling and scaling can occur in pipes, valves, and process equipment throughout the mill. Deposits of fibers, coatings, fillers, and other contaminants can accumulate over time, leading to flow restrictions, pressure drops, and reduced equipment performance. Scaling can occur when suspended minerals in the process water or steam deposit on the surfaces, leading to reduced flow capacity and potential equipment damage.

Screens and Filters

Paper mills use screens and filters to remove impurities and contaminants from the process water and pulp slurry. Fouling can occur on these screens due to the accumulation of fibers, fillers, and other suspended solids, affecting their efficiency and requiring periodic cleaning. Scaling can also occur when minerals in the water or pulp deposit on the screens, reducing the effectiveness of filtration.

Boilers and Steam Systems

Scaling can be a significant issue in boilers and steam systems. When water is heated to produce steam, minerals present in the water can precipitate and form scale on heat transfer surfaces, such as boiler tubes and heat exchangers. Scaling reduces heat transfer efficiency, increases energy consumption, and can lead to equipment failures if not properly addressed through chemical treatment or descaling procedures.

How Agitate protects the Paper Industry

Agitate is utilised in the paper industry to prevent fouling on various equipment involved in the papermaking process, such as pipes, screens, and rollers. Fouling problems in paper mill equipment can occur due to the accumulation of unwanted deposits, such as organic matter, biofilms, mineral scales, or pitch on the surfaces of the equipment. These deposits can affect the efficiency and performance of the equipment, leading to reduced productivity and increased maintenance requirements. Agitate improves the equipment performance and uptime, enhanced dispersion and mixing, is non-intrusive and helps with energy efficiency.
