The removal efficiency of 22 selected trace organic contaminants by sequential application of granular activated carbon (GAC) and simultaneous application of powdered activated carbon (PAC) with membrane bioreactor (MBR) was compared in this study. Both sequential application of GAC following MBR treatment (MBR-GAC) and simultaneous application of PAC within MBR (PAC-MBR) achieved improved remo...

Haynes, W. C. (Northern Regional Research Laboratory, Peoria, Ill.), and Lenora J. Rhodes. Spore formation by Bacillus popilliae in liquid medium containing activated carbon. J. Bacteriol. 91:2270-2274. 1966.-Heretofore, it has not been found possible to evoke sporulation of Bacillus popilliae in liquid culture. We have discovered that sporulation will occur in tryptone-glucose-yeast extract br...

\ INTRODUCTION Utilization of adsorption on solid surfaces was exercised for the first time in 1785. Practical application of unactivated carbon filters, and powdered carbon were first demonstrated in the American water treatment plant, and a municipal treatment plant in New Jersey, in 1883 and 1930, respectively. The use of activated carbon became widespread in the next few decades. At present...

ABSTRACT Introduction: Due to environmental and human health concerns related to humic acid (HA), mainly leading to disinfection by-products creation, removal or reduction of this matters is a necessary for drinking water suppliers. Based on resistive economy map road and move to self-sufficiency, it is necessary to produce our need in water treatment industry. One of the main co...

The main objectives of this study were to remove surface-active agents and to predict the adsorption rejection models.  The effects of surfactant concentration and PAC amount on the adsorption were determined. For both surfactants, It was found that the adsorption values also increased when PAC amount increased. It was observed that the rejection values are different for the adsorption of C...

2-Methylisoborneol (MIB) and geosmin are naturally occurring compounds responsible for musty-earthy taste and odor in public drinking-water supplies, a severe problem faced by many utilities throughout the world. In this study, we investigated adsorptive removal of these compounds by superfine powdered activation carbon (SPAC, particle size <1 μm) produced by novel micro-grinding of powdered ac...
