Mechanical / hydraulic
Dimensions:
- Diameter: 7.9 inches (201 mm)
- Length: 40 inches (1,016 mm)
- Permeate tube outer diameter: 1.125 inches (29 mm)
Operating Information
- All elements are wet tested, treated with tested feed water solution, and vacuum packed in oxygen barrier bags with deoxidant inside.
- To prevent biological growth during system shutdown, it is recommended to perform 30-60 minutes flushing of Toray elements with seawater once every two days.
- Permeate from the first hour of operation shall be discarded.
- The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void the element Limited Warranty.
