The effect of surfactants on

The greywater with the current detergent (powdered detergent soap (NSN 7930-00-281-4731, NuGentec, Emeryville, California) effectively reduced the E. coli concentration in the synthetic dishwater along with the anionic and nonionic surfactants. The presence of surfactants showed 97.8–99.8% reduction of E. Coli within 1 h and the rate of microbial decay was 2.5 times faster compared to the water without any detergent or surfactant. With the exception of the cationic surfactant, the effect of surfactant type on the survival of E.
