Plastic Pall ring, as an efficient and environmentally friendly filter material, plays an important role in the field of sewage treatment. Its unique ring structure and material characteristics enable it to fully capture and remove suspended substances, organic matter and other impurities in sewage during the filtration process, significantly improving water quality.

The filtration effect of plastic pall rings mainly depends on their high porosity and specific surface area. These characteristics allow sewage to be fully in contact with the filler surface when passing through the Pall ring, thereby effectively removing contaminants therein. In addition, plastic pall rings have good corrosion resistance, can work stably in various corrosive environments and extend service life.

In terms of specific gravity, plastic pall rings usually have a lighter weight. This is due to the high-quality plastic materials it uses, such as polypropylene. The lighter specific gravity not only makes the plastic Pall ring more convenient during transportation and installation, but also reduces the requirements for support structures and saves costs.

The main uses of plastic Pall rings are in environmental protection fields such as sewage treatment and air purification. In sewage treatment, it acts as a filter medium to effectively remove impurities in sewage and improve water quality; in air purification, it can capture and remove harmful gases and particulate matter in the air to protect human health.
