Improved solids management is promised by a new range of ultrafiltration cartridges from Koch Membrane Systems, a developer and manufacturer of membranes and membrane filtration systems.
A hollow fibre technology, the PURON® MP ultrafiltration cartridge is designed for high-solids water and wastewater applications, including surface water treatment, reverse osmosis (RO) pretreatment, and tertiary wastewater treatment. The PURON MP “simplifies operation, eliminates clarifier pretreatment in many applications, minimizes downtime, and reduces chemical usage to provide a lower total cost of ownership”, says the firm.
The PURON MP line fills an important niche within Koch’s KMS family of ultrafiltration membranes, with an average continuous solids tolerance of up to 250 mg/L. It features an advanced cartridge design for better solids management and a virtually unbreakable reinforced hollow fibre for superior reliability. The addition of the PURON MP line allows KMS to offer a more complete range of ultrafiltration products.
Koch claims the PURON MP has a unique construction that offers advantages over alternatives.
The PURON MP ultrafiltration system also features a “unique single-potting cartridge design” that Koch says allows air scouring to penetrate the fibre bundle more completely, releasing accumulated solids to the bottom where they are easily drained away. The cartridge uses the same virtually unbreakable reinforced fibre already made popular by other products in the PURON submerged hollow fibre product line.
The combination of durable reinforced hollow fibres and unique single-potted cartridge configuration is claimed to make the PURON MP cartridge an unparalleled solution for high solids water treatment. According to Koch: “The PURON MP design finds the perfect balance between reliable, efficient performance and high quality output.”
