FilmTec™ ECO PRO-440 Membrane Element

Dow Filmtec™ ECO PRO-440 is a high-performance reverse osmosis element with low energy consumption. Suitablefor purification of water with medium level of mineralization. It provides highquality water at low operating costs.

The Dow Filmtec™ ECO PRO-440 membrane element operates at pressure minimal for reverse osmosis, by this reducing energy consumption.

Maintenance

Before launch of the reverse osmosis system preliminary preparation of the membrane, refill of the elements, adjustment of the devices and other system checks should be performed.

Avoid any major pressure or flow surges inside the spiral-wound elements inthe middle of launch, stop, cleaning etc. to avoid risk of damage infliction tothe membrane. During the launch it is recommended to gradually switch thesystem from standstill to operational mode following the steps:

• gradually increase feed water pressure during 30-60 seconds
• operational rate of the flows should be developed gradually during 15-20 seconds
• permeate obtained within the first hour of operation is discharged

Important information

• After the initial soaking always keep the elements wet.
• To prevent biofouling during long operation breaks it is recommended to submerge the membrane elements into preservative solutions.

Maximum pressure drop along the full length of the housing makes 2.1 bar.
