The silver-impregnated porous pot filter (Figure 5) used in this study was developed by the Tshwane University Water Research Group (Pretoria, South Africa) as part of a previous project of the Water Research Commission of South Africa (WRC Project No. K8/810). A mixture of ball clay, sawdust, paper fibre and silver nitrate solution (23.5 g) was moulded into a pot shape. The SIPP is similar to the ceramic silver-impregnated pot filter (CSF) described by Lantagne and co-workers [22]. However, the fabrication process the SIPP was modified to include AgNO3 in the clay mixture prior to initial firing, instead of being coated with a 2 mL solution of colloidal silver (3.2% in 250 mL water) after firing, as described by Lantagne and co-workers [22]. The silver nitrate acts as a disinfectant due to the bacteriostatic properties of the nano-silver particles [23]. The complete water treatment system consists of the pot filter (maximum capacity 5–6 L) that is contained in a 10 L plastic receptacle (height 24 cm, diameter 26 cm) (Figure 5a,b), which is positioned on top of a 20 L collection bucket (height 33.5 cm, diameter 32 cm). The contaminated water is poured into the clay pot and slowly drips through the fine pores of the clay element into the collection vessel. A small spigot is used to withdraw water for drinking and to prevent the contamination of filtered water by dirty hands or utensils with which water is drawn (Figure 5b).
