iSep™ Ultrafiltration Modules
iSep™, or Integrated SpiraSep™ modules, represent the latest evolution of the SpiraSep™ product line. Developed to eliminate the needs for an external tank, an iSep™ system delivers the same high-quality permeate as its older cousin with the additional benefits of reduced footprint, higher membrane area, integrated aeration and the ability to quickly drain solids from the modules between backwashes.
iSep™ is an ultrafiltration membrane designed for high fouling water and wastewater streams that provides a lower overall cost to plant owners. Extensive pre-treatment for UF systems, such as clarifiers, adds significant and unnecessary cost, footprint, and complexity. With the ability to directly treat some of the most difficult water and wastewater streams, iSep is able to drastically reduce capital and operational costs while simplifying the overall treatment process.
INTEGRATED TANK DESIGN
Membrane element and tank have been integrated into a single, encapsulated module eliminating the need for a large process tank.
High tank intensity design allows for frequent draining, effectively purging solids from the membrane module resulting in lower fouling.
The open flow channels enable aggressive air scouring where bubbles “scrub” the membrane surface clean.
HIGH EFFLUENT QUALITY
The strong, durable design of the iSep element eliminates mechanical failures, ensuring high quality effluent throughout the life of the membrane system.
LOW FOULING CHEMISTRY
The hydrophilic 0.03 micron chemistry enhances membrane fouling resistance and permeability characteristics. Microdyn-Nadir engineers developed a specially-formulated low-fouling membrane chemistry that increases permeability, reduces fouling, and lowers energy consumption.
Periodic backwash purges particulate matter from the membrane surface.
