Soft Drinks Incoming Water Treatment

Conventional water treatment upstream of nanofiltration and reverse-osmosis systems can include sand filtration, flocculations, ion exchange resins and cartridge filtration. For a more economical and reliable approach, Pall has developed a compact system that uses hollow fiber modules for the replacement of most conventional water treatment steps upstream of reverse osmosis or nanofiltration.

Since membrane technology provides a positive barrier, Pall Aria™ system modules provide a much higher security against water-borne contamination than traditional system. The hollow fiber membranes have low fouling characteristics and are mechanically strong so that they can be backflushed to ensure stable operation. The quality of the filtered water meets requirements and remains stable even if the raw water quality is variable. The hollow fibers remove oxidized iron and manganese and organic contaminants. They provide exceptional security for microbial contaminants such as molds and cysts.

Filters with Ultipleat® Configuration

Profile filters with Ultipleat configuration use continuous Profile membrane in a proprietary crescent-shaped pleat structure. This design is also available for Pall Ultipor GF Plus filters. A patented spiral wrap is attached to each pleat to allow for uniform flow through each pleat. The benefit of the Ultipleat configuration is a reduced pressure drop (as low as one-fifteenth that of conventional depth filters) and higher flow rate that results in unsurpassed filter service life.

Benefits of Pall Filters with Ultipleat Construction

• Uniform flow distribution with Ultipleat construction, which can provide a longer service life
• Patented spiral wrap bonded to each pleat, maintains a uniform flow through pleats and prevents pleat collapse and bunching
• Longer life than many pleated polypropylene membrane filters, resulting in lower costs and reduced change-outs
• Higher flow rate and lower differential pressure than pleated and depth media capacity

High-Flow Filters with Ultipleat Construction

Pall has addressed the need for an economic and reliable particulate filter system designed for high-flow applications—a solution that eliminates having to settle for the traditional systems, bag filters or cartridge filter which truly do not meet all process requirements. Pall Profile and Ultipor (resin-bonded glass fiber) filters are available in an Ultipleat High-Flow filter configuration. These products combine the benefits of the membrane (resin-bonded glass fiber or Profile) and the Ultipleat crescent-shaped pleat geometry into a design that allows for flows up to 500 GPM per membrane cartridge.

Ultipleat High-Flow filters utilize a 6-inch diameter and a 40 - 60 inch length to maximize the ratio between surface area and cross-sectional area and to minimize core pressure drop. The flow direction is in to out so that contaminants can be collected inside the filter for easy disposal. The filters are coreless, with an all-plastic construction, to minimize waste disposal costs. Micron ratings from 2 to 20 microns are available.

The Ultipleat High-Flow filter design allows for a smaller footprint with fewer filters to change-out.
