Özet

Quartz sand is commonly used in filter beds to remove suspended solids. In Turkey, however, sources of sand suitable for filtration are limited and costly, making it necessary for utilities to examine alternative bed materials. Crushed raw perlite, which is plentiful along Turkey's Aegean Coast, was examined for its suitability as a substitute for sand. Sieve analysis, porosity, particle density, and solubility in 20 percent concentrated HCl acid test results as well as the costs of perlite and sand were compared.
