How long will the resin last with a Merlin RO?
« on: June 23, 2005, 06:22:39 pm »
HI, ive set my new merlin ro up and just need to add the di resin filter,ive got a 29.9ltr vessel(empty at the moment),once ive put my water through the merlin ro,
how long should the resin last using a 25ltr bag? i should be using (very loose guess)about 150 ltrs of water a day for the moment,hope to use a lot more as better jobs come in. ;D

Hi Roy,

What's your tap water TDS, and what reading do you get from your Merlin ?

Roy,

That's why your resin life is so long.  Your system probably removes 98% of the 118 ppm in your tap water, and you're then feeding your resin with product water at only 2 or 3 ppm TDS.  If your tap water was, say 400ppm, and you were using a Merlin, you'ld be feeding water at 28 ppm to your resin, and it would only last one tenth as long.

Horses for courses !

Or for any RO system built round a low pressure 4" diameter x 40" long membrane.
