“…Arsenic is highly toxic to humans in even small concentrations and has been identified as the "poison of kings and the king of poisons". Independent of the source of As in a water supply, various technologies are being implemented to remove it, such as coagulation (Song & Gallegos-García, 2014), adsorption in nanoparticles (Martinez-Vargas et al, 2018;Ivanets et al, 2018), sedimentationfiltration (Terracciano, Ge, & Meng, 2015), membrane filtration and…”

“…Some of these include coagulation (17,18), sedimentation-filtration (19,20), nanofiltration (21,22), reverse osmosis (21,23), fluidized-bed sand reactor, and subsurface groundwater treatment (24). Nevertheless, these technologies are inappropriate for application in rural communities (25).…”

Background: Among the various adverse pollutants in water, coliform bacteria and arsenic are very important. Drinking of arseniccontaminated water has become a serious threat to public health and has affected millions of people across the world. Objectives: The aim of this study was to investigate the removal of arsenic and coliform bacteria from drinking water in small communities with the use of a conventional Slow Sand Filter (SSF) and modified filter by slag (SMF) and Zeolite (ZMF). Methods: In this study, initial concentrations of arsenic were 0.073, 0.11, 0.171, 0.21, 0.24, and 0.33 mg/l and the initial number of coliform bacteria was 4*10 6 MPN/100 mL. Arsenic and coliform bacteria samples were taken every 24 and 48 hours, respectively.
