Clean It Up

I use a DI only set up.
Just wondering if there are there any filters that you can put on before the DI vessels to make the resin last longer that won't slow down tank filling?
I'm reluctant to use a full RO system because I'd like to be able to fill the tank up quickly on site if need be.

8) I use a debris filter the container is about £28 but the filters are only a £1 a go from Wintex.co.uk 8)

What you need is another DI vessel, when your resin next reaches 001/002ppm, fill the new vessel with fresh resin & use your existing one to pre-filter it. Then just carry on swapping them round each time one expires. ;)
I would have them on your van though to pump through(resin will last longer this way too) & fill your tank with tap water. pure water on demand, fill up at mains pressure at home & on site. ;)

Thanks. I actually do that already, but I was wondering if it is worth putting a carbon filter on too?
Is a debris filter the same as a sediment filter?
-
Two partical and two carbon filters, it also knocks a bit off the TDS, therefore reducing the work your DI filter has to do.

Thanks pur.
Would water run through those filters at the same speed and pressure as the DI vessel?
-
I always thought that you only needed carbon/sediment filter to protect the RO membrane.
With DI set up surely its just DI and then a mesh filter to protect the pump from debris.
As for making it last longer, well it has to trap all of the impurities no matter what so dont know if its possible to make it last longer oter than using RO. Or have I got that wrong?

Prefilters will slow the flow down slightly when they are new and even more as they become exhausted. Basically, the smaller the micron size on the filter, the slower the flow rate becomes. It is a minimal difference, but a difference none the less.
A carbon filter is a good idea if you own the resin and are regenerating it yourself. Carbon removes the chlorine from the water and the chlorine oxidizes the DI resin. Removing the chlorine from the resin will give the resin a longer life. This means, more regens as opposed to more gallons per regen though.
