O.C. "Reef-Chem" Bulk chemicals

[christyf5]

Right, I actually use those ones so you'll be hearing from me in about 10lbs

I meant these ones though:

Ultra Pure (Ion Exchange) DI Resins to refill DI cartridges.
Strong base anion exchange resin
Strong acid cation exchange resin

Whats the difference between these two resins? Or am I missing something here?

Oh! Oh well, someone might want to know the additional info I posted.

The two resins are typically mixed together in what is called a mixed bed resin. The two resins work together to polish separate impurities (ions) out of the water.

We will also be selling Nuclear grade mixed bed resins that are even higher quality.

Oh ok that makes sense. Thanks for the info.

Nuclear grade. Is that like a wedgie versus an atomic wedgie?

Purolite Nuclear grade polishing mixed bed resins offer a selection of products to address the diversity of conditions encountered in nuclear plant operations and insure optimum performance. The Purolite® nuclear grade mixed bed resins are primarily equivalence blends for maximum exchangeable capacity. Strong acid cation rich mixed beds are available for high cation and amine circuits. Contact your Purolite specialist for additional details.

When selecting mixed bed products it is essential to consider the objective for the resin. Resins, both cations and anions with high capacity will have greater selectivity for ions however kinetics will slow. Therefore higher capacity resins will result in lower ionic leakage but may not offer total loading capacity. Removing trace impurities from high purity water, such as conditions found in boiling water reactors (BWR) higher capacity resins will allow lower leakage. Whereas, in the primary circuit or a pressurized water reactor (PWR) medium crossed link resin will control ionic leakage yet achieve a greater total loading, thus reducing resin use and waste generation.

Mix beds with macroporous strong acid cation resin and gel anion resin offer a unique benefit of high selectivity and good kinetics achieving an efficient treatment for almost all nuclear systems.

I think the DI resins in RO/DI units have a mixture of both anion and cation resins.

Doh....... that was a quick response.

Absolutely correct!

There has been a lot of talk about different sources of Calcium Chloride and the ill effects of some (not all) of the DOW products. Also there is some huge differences in Anhydrous Pellet verses Crystalline Calcium Chloride Dihydrate.
What will you be supplying?

Thanks

The Dow products that were recently deemed as unsafe for continuous use are now deemed as fairly safe again as explained on this Reef Central thread with input from Randy Holmes Farley.

The Calcium Chloride we will be selling is Crystalline Calcium Chloride Dihydrate. Our supplier lists this Calcium as Calcium Chloride High test fines (food grade).

Hope that helps.

Thanks yes that helps a lot
