DIY DI water purification

[May&Bruce]

I am about to do a DIY DI water system. I have access to 'mixed bed' DI resin, which is what the system will use. But, the are different specs/types of DI resin. Can anyone tell me anything about any special requirements for specifying DI resin?

I believe

Strong base anion resin and

Strong acid cation resin(hydrogen form) would be the choice for ur mixedbed resins.

nitrate and silica mostly removed by the anion resins.

ok...i bought all the bits today, so guess what i will be doing tmr night and Sat?

Prices as follows:

3 x filter housings - clear plastic @$26 = S$78

1 x 5 micron sedminet filter cartridge (came with the housings)

1 x Granular Activated Carbon cartridge S$21

1 x 3.5 litre bag of mixed bed Di resin S$45 (will be enough for 2 or 3 fills)

Joiner hose fittings all came with the housings, so no extra costs.

Total price is S$144, which includes spare sediment filter and enough DI resin to do 2 x refills.
