Poroplate septa are available in a variety of filtration ratings, all providing low differential pressures and high collapse strength. Poroplate media are readily constructed in cylindrical tubes, or custom fabrications for Funda-type retrofits or resin traps. The high strength and corrosion resistance of Poroplate septa provide for enhanced precoating, aggressive backwashing and extended service life. This enhances the installation and removal of septa from the filter demineralizer to reduce installation cost and associated soft labor charges. In nuclear plants, the associated savings as a result of reduced radiation exposure is dramatic.
Standard designs are available for top and bottom tubesheet assemblies.
This leads to extended run times, higher decontamination factors, reduced spent resin disposal volumes and lower operating costs. Fit for severe service, Poroplate septa design, materials and manufacturing provide the structural integrity required for repeated, high-pressure backwashing. Designed to decrease disposal costs, Poroplate filter septa provide economical, long life in these relatively high flow-rate applications. Purolator engineering and design flexibility provide application-matched Poroplate septa for dual use in fuel pool and radwaste services, if required. Poroplate septa maintain adequate water quality to minimize spent fuel rod contamination and radiation exposure to the operators.
