High-flow Backwashable Filtration Systems

Background

91Ó°ÊÓ has provided quality products and services to the nuclear industry for more than a decade. Using this experience, and incorporating unique concepts, it has developed a high-flow backwashable filtration system that can process at high flow rates and at filter sizes to the sub-micron range. These systems provide a cost-effective way to meet diverse filtration demands.

Other systems employ single-use cartridge filters that are easily clogged and require multiple change-outs during a clean-up project. This increases the duration of the project and the radwaste volume generated. By using 91Ó°ÊÓ’s backwashable filtration technology, filter changes are greatly minimized, which saves costs and outage time, and reduces radwaste and radiation exposure.

Description

91Ó°ÊÓ’s standard portable filtration system offers high flow rates. However, the system can be modified to suit lower-flow applications. The combination of backwashable filters and capabilities to meet specific customer needs makes 91Ó°ÊÓ’s filtration systems very versatile.

The high-flow backwashable filtration system is ideal for suppression pool or fuel pool projects, and helps to maintain water clarity during underwater cutting and decommissioning evolutions.

Benefits

The 91Ó°ÊÓ backwash filter design offers significant advantages over traditional cartridge filtration. These advantages include:
