If you have water or fluid in your process system, it’s likely you have solids build-up. These solids can cause difficulty in the production process. Basic knowledge about particle size measurement, total suspended solids, fluid types, and filtration screen basics is helpful when determining the correct filtration system to implement or when troubleshooting a problematic system.

During the paper manufacturing process, many scientific processes are manipulated to control the physical properties of the paper such as weight, thickness, color, strength, and moisture. While most of these variables remain fixed after the paper is made, the moisture content begins to change almost immediately.

The papermaker is faced with many challenges when trying to keep fabrics and roll covers clean. Contaminants are deposited and consequently forced into the void volume of fabrics, reducing permeability, creating holes in the sheet, and other runnability issues. In addition, deposits on roll surfaces cause picking or sheet marking.

Pressure filters are used extensively in the papermaking process and often go unnoticed as they effortlessly operate in stable mill water systems. They quietly perform as designed preventing shower nozzles from plugging and assuring that paper machine clothing remains clean. Pressure filters protect process equipment by removing contaminants such as sand and silt from mill water.
