Siemens improves disc filter

Siemens Water Technologies has made some product enhancements to its Forty-X disc filter, which was previously known as the Spider Disc Filter. The tertiary filter disc technology incorporates several new product improvements including a pressure-assisted seal, a trash-tolerant box design, and sliding tank covers.

The Forty-X Disc Filter incorporates a proprietary pleated panel design for use in applications such as municipal tertiary filtration, water reuse, and process water filtration. The pleated media configuration reportedly increases the surface filtration area by 40% and reduces the possibility of media deformation and reaping when compared to traditional flat panel, woven disc filters.

The new pressure-assisted seal added to the pleated panel's now eliminates leak points and increases throughput capacity, allowing the filtration panel to sustain and operate at twice the headloss.

After flowing through the disc filter's new proprietary filtration box, trash material is rejected out of the system. This ensures the unhindered flow of water between panels and the proper rejection of plastics, algae clumps, and other floatables.

Finally, stainless steel sliding covers have been added for increased operator safety. The covers, which enclose the disc/drum's entire internal assembly, make accessibility and maintenance easier.
