Description
FilmTec™ Seamaxx™–440 Elements are the choice for seawater systems operating at low to medium levels of salinity and temperature, as well as for brackish water with relatively high salinity. The element’s flowrate is significantly above flowrates of any other SWRO element currently available in the market. This extraordinary high element productivity leads to substantial savings, primarily in energy consumption when compared to conventional low-energy SWRO products. In addition, FilmTec™ Seamaxx™–440 includes the typical FilmTec™ Element features:
- The 28-mil feed spacer combines low differential pressure with low cleaning frequency and high cleaning efficiency.
- The oxidative-free membrane manufacturing process results in high membrane robustness and long-term stable performance.
- The widest pH range for cleanings (pH 1 – 13) allows effective cleanings even in cases of severe fouling.
- The automated, precision fabrication gives a greater number of shorter membrane leaves thus reducing fouling while maximizing element efficiency.
FilmTec™ Seamaxx™-440 Elements are tested on flow and rejection performance using
a standard test at 600 psi. Potential defects in element construction are detected and
elements which do not comply with the quality protocol are discarded. A 600-psi standard
test was introduced to specifically account for the high permeability of this seawater
element. The results of standard tests performed at 600 psi and 8% recovery are different
from the nominal performance condition of 800 psi and 8% recovery. The test conditions
for the Certificate of Analysis are defined in the table below.
