Do you suspect there is any physical damage to the membranes that would prevent them from being reused?

Yes

Membrane damage

What is the tested permeability of your membranes (LMH/bar)?

Tested permeability (LMH/bar):

Find out more about standard testing methods.

What is the tested NaCl rejection of your membranes? (% NaCl rejection)

Tested permeability (LMH/bar):

Please order the following criteria in the order of importance for your project (drag and drop):

Financial
Effort required
Environmental impact
Landfill impact
Public perception

Rank from most important to least important.

Direct reuse as a high quality seawater RO membranes.

Direct reuse as a high quality brackishwater RO membranes.

Direct reuse as a medium quality brackishwater RO membranes.

Direct reuse as a low quality brackishwater RO membranes.

Direct reuse as a medium quality nanofiltration membranes.

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.	-

A suitable alternative is:
