Ultrafiltration (UF) is a key process step in many wastewater reuse schemes – including Reverse Osmosis (RO) pretreatment. The job of a UF system is essentially the complete removal of solids, producing permeate with a low Silt Density Index (SDI) and high Log Removal Values (LRV) of pathogens. Pressurized In-to-Out UF hollow fiber cartridges are widely used for this type of application.
For high solids applications, however, submerged hollow fiber modules offer a much better solids tolerance and thus improved treatment capabilities. Submerged modules have been a proven technology in membrane bioreactor (MBR) applications. The new PURON HF (High Flow) builds on the design of PURON MBR module but with a much higher membrane packing density. It offers 44% more membrane area than the current MBR module – within the same product dimension. The result is a high throughput, compact wastewater solution that can be implemented for a low life-cycle cost. With its reinforced hollow fiber and proven single-header, central aeration design the PURON HF is ideal for tertiary applications including RO pretreatment and surface water treatment.
This webinar will:
• Summarize global markets for water and reuse;
• Examine existing technologies for wastewater reuse;
• Introduce the new PURON HF submerged membrane module and its key design features;
• Explain how its new operating modes and protocols improve system recovery rates and lower life-cycle costs;
• Look at operating data from pilot plants;
• Present general design aspects of submerged membrane technology for tertiary treatment applications
