The poor access to water quality for Nigerians has pushed the designing of new trend silver nitrate impregnated locally made Point-Of-Use (POU) ceramic filters enhance purification efficiency household use. This study utilized nitrate-molded prepared with Kaolin from Owode, silt soil, sodium silicate, sawdust, and distilled in three varying proportions ascertain pollution removal efficiencies. Heating was carried out by firing at 900 °C further preheating 400 after dipping solution. Silver nanoparticle dissociated particle discharge filter pot painted 0.03 mg/g casein-covered nAg or AgNO3 were estimated as an element pH (5-9), ionic strength (1-50mM), cation species (Na+, Ca2+, Mg2+). delivery constrained disintegration Ag+ resulting exchange measures, paying little heed structure applied. Water analysis both heavy metals (Pb Cd) microbial load (E. coli) evaluated, corroborate maximum efficiency. It observed that kaolin-sawdust showed a constant effective disinfection loads. minimum flow rates 4.97 mL/min batch used Iju River sample one (AF1) 4.98 two (AF2) having porosity 49.05% 50.00%, whereas 5 higher rate borehole (BF1) well (CF2) 50.00%. Significantly, results obtained show are suitable point-of-use application urban rural areas developing countries such Nigeria.
