RODI Upgrade

I think I need to change my RO membrane and feel bad about all my wastewater going down the drain, so thinking I will upgrade to dual membranes and add booster pump (think my pressure is 38 psi).
Questions:
If I have dual membranes, can I use an old one that is functioning at ~90%?
Any recommendations on booster pump or specs?
 
I think it'd be fine to keep the old membrane assuming there's nothing physically wrong with it, if you do keep it I'd let that be the first membrane since the second one gets more gunk through it. But like Mike said, 8800 model one is fairly standard.
