Description
The FilmTec™ Fortilife™ product family offers solutions for industrial-users to improve water efficiency by incorporating membrane and element design innovations that enable systems to clean-less, recover-more, and waste-less.
The FilmTec™ Fortilife™ CR100 Element is an advanced element design for treating and recycling highly biofouling prone waters, such as wastewater. It utilizes an ultra-low pressure drop element design and a durable, fouling resistant, and cleanable membrane chemistry that provides outstanding solute rejection over a long element lifetime. These benefits are available with either standard (CR100) or iLEC™ (CR100i) end cap designs.
Important Information
Proper start-up of reverse osmosis water treatment systems is essential to prepare the membranes for operating service and to prevent membrane damage due to overfeeding or hydraulic shock. Following the proper start-up sequence also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved.
Before initiating system start-up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration and other system checks should be completed.
Operation Guidelines
Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage. During start-up, a gradual change from a standstill to operating state is recommended as follows:
- Feed pressure should be increased gradually over a 30-60 second time frame.
- Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds.
