Zeolite Heat Storage: Key Parameters from Experimental …
Due to their high (nearly 100 %) zeolite content, the adsorption capacity of the binder-free zeolite beads is close to that of pure zeolite powder (Tab. 1) 10. As an additional advantage, it was found that, by means of this special manufacturing process, an (as compared to typical binder-containing beads) open secondary transport system is ...

Zeolite Australia – A Leading Edge Technology Developer
Mr Joe Papadatos Residential Pool Filtration. "With our switch to Zeolite we only need to backwash monthly, saving around 250,000 litres of water per season, an estimated $1,800 on chemicals and probably $4,000 on heating costs. I'm saving my council well in excess of $5,000 per season in a 700,000 litre pool!"

The XRD pattern is very similar to those of the reference faujasite zeolite structure. In addition, the SiO 2 /Al 2 O 3 ratio of these granules obtained by EDX analysis is equal to 1.96 revealing that the tested granules were composed of the NaY zeolite type. The FTIR spectrum also agrees with this finding (see Fig. 3).
