-The use of powdered activated carbon treatment (PACT), based on simultaneous adsorption and biodegradation, is effective for treating organic toxic pollutants, present in industrial wastewaters. Removal of phenol and aniline from aqueous solutions by biological treatment alone, by adsorption on powdered activated carbon (PAC) alone and by simultaneous adsorption and biodegradation were compare...

in this research, the effects of the addition of powdered activated carbon (pac) into the aeration zone of an activated-sludge (as) system for treating tehran oil refinery effluent, was investigated during more than 12 months in a pact pilot-scale model. besides the evaluation of organics removal efficiency and determination of basic design factors kinetic coefficients, a series of experiments ...

In both research and practice of water purification technology, superfine powdered activated carbon (SPAC), which is produced from conventionally sized powdered activated carbon (PAC) by wet milling in a bead mill, has attracted attention for its higher adsorption capacity of contaminants as well as the higher adsorptive uptake speed than its parent PAC. However, the previous SPAC researches on...

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 consumed material...

Granular activated carbon (GAC) and powdered (PAC) are the two most common forms of with varying particle size range. The goal this study was to analyze key factors (particle activation temperature) affecting surface characteristics GAC PAC derived from palm kernel shell (PKS). morphology suggested that pore network in PKS-PAC is more developed than PKS-GAC owing presence a micropore structure ...

this research was done in order to determine the basic criteria for “tehran oil refinery effluemt treatmentunit” to prove the feasibility of the application of powdered activated carbon in aeration zone of activated sludge system. the main stages of this research included: determination of qualitative and quantitative characteristics of raw wastewater preparation of two pilot scale units of act...

As a pretreatment for membrane microfiltration (MF), the use of powdered activated carbon (PAC) with a particle size much smaller than that of conventional PAC (super-powdered PAC, or S-PAC) has been proposed to enhance the removal of dissolved substances. In this paper, another advantage of S-PAC as a pretreatment for MF is described: the use of S-PAC attenuates trans-membrane pressure increas...

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...

Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. During the past decade, these findings have spawned investigations and research into suitable treatment technolog...
