The use of porous pottery jugs (fired clay) to the purification of drinking water and reduction
of heavy metals and other contaminants is the aim of this study. A total of twenty-eight samples
of drinking tap water tested for pH, Turbidity, TDS, Electrical Conductivity, Salinity, TH, Ca++
hardness, Mg++ hardness and Total Coliform bacteria, in addition to some heavy metals (Pb, Zn,
Mn, Fe, Cd and Cu) in water before and after filtration also inside the jugs through 24 hour. The
paper discusses the ability for this technique to reduce such these pollutants that may be
remaining after treatment. Pottery jugs (B) represented the best one in WQI and AWQI that may
be due to its composition of silt and the high quality of clay. Pottery jugs (B) able to reduce the
concentrations of turbidity, TH, Ca++ and Mg++ hardness. Also, improved its efficiency in
decreasing levels of some heavy metals as Mn, Pb, and Cd. Statistical ANOVA tests showed a
significant difference between pottery jugs with physicochemical parameters and filtration
efficiencies. The concentrations of examined physicochemical parameters and heavy metals in
drinking tap water and inside the pottery jugs and in the filtrate were within the safe limits of
EMH (2007), WHO (2011) and Egyptian Standards (EEAA, 1994) regulations, except the
concentration of Fe inside and in the filtrate, was above safe limit.
