Resin regeneration
My name is Terry Williams of Swindon Wiltshire and I am a window cleaner I use a waterfed pole system using a DI rsin filter to get zero parts per million of desolvable solids to obtain clear windows. How do you regenerate the DI resin for re-use rather than just dispose of the resin, would it be practical?

In the USA, there are companies that will sell the resin and regenerate it--for a fee. Shipping is a bit of a pain as it must be shipped damp. Still, it is cheaper than resin by a long way.

Resins are regenerated by backwashing them with an appropriate solution. The exact solution depends, among other thing, on the resin.
Once you do this, however, you have to dispose of the solution. This can be ammonia
[on
eBay or
Amazon], hydrochloric acid, sodium hydroxide, etc.
For your application, it's probably just easier and cheaper to get new resin. There are filter companies that will swap out resin tanks for regeneration at their facilities. You basically just pay a fee to have new tanks installed. Try looking for water filter or water treatment companies in your area.
