The pulp and paper industry has several applications for Hytrex cartridge filters that are often overlooked. These chemicals are mixed to form chlorine dioxide, the primary chemical in the paper bleaching process. Any contaminants can cause spotting or other flaws in the final paper product.
Hytrex filters can also offer effective protection for high-pressure spray nozzles.
These nozzles are used at several critical points in the paper making process. One such area is the drying section of the paper machine, where the paper is blotted by a series of felts that are continuously cleaned by high-pressure spray nozzles. If a nozzle plugs, and one portion of the felt is not sufficiently cleaned of paper fibers, paper quality is compromised. High-pressure water showers are also used to clean wire screens following the head box of the paper machine. The purpose of the screen is for dewatering at a specified rate.
