Calcium aluminate has been used in sewer environments since the 1940s. Initially, the drivers for its use included its resistance to sulfates in soil, rapid return to service and superior abrasion resistance.
Filtration is a commonly observed practice by winemakers across the world. For decades, minerals such as diatomite and perlite have played a vital role in the process – removing unwanted substances and leaving wine producers with clear, quality wines.
For years, virgin oils have been the in-demand ingredient in biofuels to help meet sustainability goals. Improved filtration techniques, thanks to minerals such as diatomite, mean even the most heavily contaminated waste fat can be used to run engines.
