Silver nanoparticles (AgNPs) were synthesized from biological materials (Ziziphus plant) under microwave irradiation and later theses AgNPs were used for the reduction of microbial effect in water. Fourier Transformation infrared Spectroscopy (FTIR), UV-Vis spectrophotometer and Atomic Force Microscopy (AFM) were used to characterize AgNPs. Process parameters that affect the AgNPs synthesis, such as AgNO3 concentration, microwave exposure time, amount of extract volume and pH of the solution were also studied. The best average diameter of AgNPs (80 nm) showed by AFM. Ceramic filter and tablets were prepared from local Iraqi clay which is mixed with different combustible material (date palm seed, sawdust and charcoal). The maximum apparent porosity (50.52% porosity) was obtained at a mixing ratio of clay: charcoal of 10:4. Total Bacteria Count (TBC) was measured in the filtered water and gave a result of 0.001 CFU/ml which shows that silver nanoparticles have excellent antimicrobial activity.
