NaCl rejection range (%)	Permeability range (l.m-2.h-1.bar-1)	Designation	Action	Estimated reuse lifespan (yrs)
99.9 - 99.6	> 0.45	High quality SWRO	Direct reuse as SWRO possible in normal applications	2 –5
99.7 - 99.2	> 1.6	High quality BWRO	Direct reuse as BWRO possible in normal applications	2 – 3
99.2 – 98	> 1.6	Medium quality BWRO	Direct reuse as BWRO in standard applications possible	1 – 2
98 – 96	> 1	Low quality BWRO	Direct reuse as BWRO in harsh applications where regular replacement is required	1
96 – 80	> 5	Medium quality NF	Direct reuse as NF membrane possible	-
< 96	< 5	Unsuitable for RO or NF	Membrane suitable for UF conversion.	-
