Abstract
It has been demonstrated that the ceramic pot filters (CPFs) with impregnated colloidal silver are efficient for the removal of turbidity and pathogens for household water treatment. This investigation evaluated the efficiency of two filter models for the removal of chemical contaminants (Hg, Pb, As and phenolic compounds) during 175 days. The first model is a traditional CPF impregnated with colloidal silver and the second consists of the ceramic silver-impregnated pot plus a post-filtration column with granular activated carbon and zeolite (CPF + GAC-Z). The results of the CPF showed average efficiencies of 91.5% (Hg), 92% (Pb), 50.2% (As) and 78.7% (phenols). The CPF + GAC-Z showed similar efficiencies for the removal of heavy metals (92.5% Hg, 98.1% Pb and 52.3% As) and a considerably higher efficiency for the removal of phenols (96.4%). The As concentration of the filtered water in both systems was higher than the regulatory limit. The ceramic pot was responsible for the highest removal of chemical compounds. It can be concluded that the traditional CPF is a viable option for water supply treatment at the household level for the removal of chemical contaminants. The efficiency of this filter can be improved with the post-filtration column mainly for the removal of organic constituents.

Business Connect Takeaways
Ceramic pot filters can effectively remove bacteria and turbidity from drinking water, but their performance can be influenced by factors such as water quality, filter design, and maintenance practices
Ceramic pot filters can be a cost-effective and sustainable option for household water treatment in low-resource settings, but their adoption and sustained use may require community engagement and behavior change interventions
The effectiveness of ceramic pot filters can be enhanced by combining them with other water treatment technologies such as solar disinfection or chlorination, and by promoting safe storage and handling practices for treated water.
