Description

nnnn

The Pall Disc Tube™ Module System is a major advance in Reverse

nnnn

Osmesis technology. The fluid dynamics and construction of the disc

nnnn

membrane stack result in an open channel, unrestricted and fully turbulent

nnnn

feedwater system. This means that suspended solids carried In the

nnnn

feedwater cannot be trapped or easily settle cut inside the membrane

nnnn

module. In frequent maintenance, cleaning of the membranes can be

nnnn

successfully achieved using a standard, built-in system. Round-the-clock

nnnn

reliability and product water quality are also guaranteed. These are

nnnn

achieved through Pall's adherence to the highest standards In

nnnn

components, materials, and methods of design and construction.

nnnn

Advantages of the DIscTube Module System Include:

nnnn

► Minimization of membrane scaling and fouling. The system uses short

nnnn

feed flow paths, open channels and high-packing densities to minimize

nnnn

concentration polarization and physical flow Impediments. Consequently,

nnnn

scaling and fouling are greatly reduced while high energy efficiency Is maintained.

nnnn

► Long membrane life. The combination of low membrane scaling and fouling, highly stable membranes,

nnnn

and the simple built-in cleaning system means that membrane life-expectancy Is not normally limited by

nnnn

feedwater pollution. Useful membrane life of five years or more can be expected.

nnnn

p Lower membrane replacement costs. Compared to spirally wound and hollow fiber membrane

nnnn

elements which are life-sealed at manufacture (so the complete element must be replaced at relatively

nnnn

high cost}, the DT Module system allows the replacement of individual sheets of membrane at a fraction

nnnn

of the cost

nnnn

► Easy access to all membranes. Modules can easily be opened up to permit replacement or inspection of

nnnn

each membrane cushion.

nnnn

Fail-safe unattended operation. The only moving parts are the pumps and all operating functions are

nnnn

automatically controlled and fail-safe. No special skills are required to operate the system.

nnnn

► Compact and flexible. Modular design and construction of all standard units simplifies transportation and

nnnn

Installation, and enables efficient use of floor space.

nnnn

Originally designed to produce drinking waterfrom sea water, DIscTube

nnnn

technology Is now being successfully applied to other markets such as

nnnn

leachate, petroleum contaminated water, and Industrial wastewater streams.

nnnn

In addition to RO membrane systems, DT technology can also be used In

nnnn

conjunction with mlcrofiltratlon, nanofiltratlon, and ultrafiltration membrane

nnnn

systems. DT systems also allow the use of wastewater as a demlneralize

nnnn

feeder while extending deminerallzer run length tenfold.
