Siemens’ Disc Filter Receives Title 22 Approval

The Title 22 regulation requires filtration technologies to reliably meet specific performance parameters for wastewater reuse applications. Reuse water can be used for urban landscaping, agriculture, decorative lakes and fish hatcheries, and a wide variety of industrial applications.

The data submitted to the California Department of Health Services was from an actual production unit tested in 2007 at a local water pollution control facility. The pilot test lasted for eight consecutive months and challenged the filter under a variety of hydraulic and solids load scenarios. The pleated woven cloth with absolute micron rated pores proved the consistent effluent quality of less than 2 NTU and less than 5 mg/L TSS regardless of incoming load. The high hydraulic loads also resulted with backwash percentages of less than 2% on average.

The Forty-X disc filter’s innovative woven polyester pleated panel design provides increased treatment capacity and an ultimate barrier for suspended solids in tertiary treatment processes. The inside-out filtration design allows for a higher operating headloss capability, ensuring a more sustainable operation in terms of more throughput, better feed distribution, and fewer backwash frequencies. Additional features include a trash-tolerant filter panel housing designed to prevent entrapment and accumulation of inorganic material, water pressure-assisted seals, and wind-safe sliding covers that make accessibility and maintenance easier.
