Membrane element;

Brackish water. High rejection elements. Membrane material: Composite polyamide Design: Spiral wound Dimensions: A, mm - 1016 B, mm - 200.1 C, mm - 28.6 Specification Flux, GPD: 10 300 Rejection, % (normal/minimal): 99.7 / 99.5 Area, m2 (ft2): 35 (375) Spacer, mil: 34 TEST CONDITIONS: NaCl test solution 1500 mg/l, P=1,55 MPa, T=25C, pH=7,5. Permeate recovery rate is 15%. Flux of each element in a batch may vary +25%/ -15% Nominal rejection is reached after 48 hours of continuous operation on test solution. Minimal rejection of a new element after 20 minutes test on test solution.
