Review on Dow TW30 100HR Rejection Replacement 1812 by Brad Ward

I am very disappointed with this diaphragm. It has a lower bounce rate than the one I replaced it with. I've been taking readings for more than 2 months and they haven't improved even after the membrane was fully saturated. Dry membranes take time to fully hydrate. I'm a former RO industry leader and have used a very accurate TDS meter. I have monitored the water quality, it has improved by no more than 91%. I'm not sure if this high scrap rate membrane is a Dow/Filtec manufacturing issue or a dealer defective membrane? In any case, the retention rate must be at least 98%, I even have a booster pump on my reverse osmosis system. Therefore I cannot recommend this membrane due to the poor quality.
