Abstract:
The disinfection is the final step of domestic wastewater treatment to ensure treated
water without bacteria or other microbes that cause waterborne diseases. Different techniques
have been developed to eliminate gram positive and gram negative bacteria to achieve clean
water for use. This study presents a new alternative choice by using silver nanomaterials
which synthesizes by impregnating silver nitrate (AgNO3-) to cation exchange resin (C145)
called AgNPs-C145 to be against both gram positive bacteria (Staphyloloccus aureus:
S. aureus) and gram negative bacteria (Escherischia coli: E. coli) in the water. The results
showed the formation of a prominent zone of inhibition (ZOI) for both bacteria, and the
average of ZOI size of E. coli (0.441 mm) was bigger than S. aureus (0.354 mm). The batch
tests (dose, contact time, pH, and concentration) were used to investigate the efficiency of
silver nanomaterials to be against two bacteria types. The result showed that 1.5 g/200 mL, 1
h, pH 7, 106 CFU/mL and 3 g/200 mL, 5 h, pH 7, 106 CFU/mL were the best optimum
condition to be against E. coli and S. aureus, respectively with measuring by the plate count
technique. This confirmed that AgNPs-C145 can be against both bacteria types.
