Performances of Zeolite, Coconut Shell, and Zeolite+Coconut Shell-Based Water Cartridges to Minimize Contaminants of Drinking Water

Abstract

ABSTRACTS
Performances of zeolite, coconut shell, and zeolite+coconut shell-based water cartridges to minimize contaminants of drinking waters were
conducted in the present study. The zeolite stones and coconut shell charcoal were powdered to be ≥ 60 meshes. The powders were packed into
a cartridge to provide zeolite, coconut shell, and zeolite+coconut shell (1:2) cartridges, respectively. Well waters allowed to flow through each
cartridge for a month. Thereafter, each water filtrate was harvested and analyzed numbers of parameters from four variables included in the
quality table of drinking water. The total coliform found in each 100 mL of the well water equaled to 460 MPN (most possible number) while
the fecal coli equaled to 150. When the well water flowed through the developing cartridges, the MPN content varied which depended on the
cartridge materials qualitative compositions. Total coliform remained in water filtrates of the well waters flowed through the cartridges made of
zeolite, coconut charcoal, and their mixture (1:2 by volume) were 38, 240, and 96 MPN, respectively. These developed cartridges, therefore,
could remove these total coliform from the well waters by 92, 48, and 79 %, respectively. Overall, the performance of the developed cartridge
made of zeolite was highest among those cartridges.
