et al., Mod Chem appl 2015, 3:4 http://dx. Abstract Biowaste from neem (Azadirachta indica) were used to prepare activated carbon using ZnCl 2 and H 3 PO 4 as activating agents. The efficiency of the prepared adsorbents; Neem Husks activated with ZnCl 2 (NHZ), Neem Husks activated with H 3 PO 4 (NHH), Neem Seed activated with ZnCl 2 (NCZ) and Neem seed activated with H PO 4 (NCH) to remove microbes from wastewater were evaluated. The effect of initial volume of wastewater and time of exposure

The result shows high performance of the adsorbents in microbial load reduction. The bacterial load was greatly reduced by 99.4% (2600 CFU/100 cm 3 ), 99.3% (3000 CFU/100 cm 3 ), 99.3% (3100 CFU/100 cm 3 ) and 99.3% (2800 CFU/100 ml) by the NCZ, NCH, NHZ and NHH samples respectively. The fungal load was also decreased significantly by NCZ, NCH, NHZ and NHH samples to 88.75% (2700 CFU/100 cm 3 ), 90.0% (2400 CFU/100 cm 3 ), 85.83% (3400 CFU/100 cm 3 ) and 90.42% (2300 CFU/100 cm 3 ) respectively. NCZ was the most effective of the prepared carbon, with a 99.4% reduction of the bacterial load.
