Comparison of natural organic matter adsorption capacities of super-powdered activated carbon and powdered activated Carbon.
We examined the natural organic matter (NOM) adsorption characteristics of super-powdered activated carbon (S-PAC) produced by pulverizing commercially available, normal PAC to a submicron particle size range. The adsorption capacities of S-PAC for NOM and polystyrene sulfonates (PSS) with molecular weights (MWs) of 1.1, 1.8, and 4.6 kDa, which we used as model compounds, were considerably high...
متن کاملEffects of super-powdered activated carbon pretreatment on coagulation and trans-membrane pressure buildup during microfiltration.
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...
متن کاملPerformance Evaluation of Combined Process of Powdered Activated Carbon-Activated Sludge (PACT) in Textile Dye Removal
Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...
متن کاملModeling Mercury Control with Powdered Activated Carbon
Fulland pilot-scale data has been collected on the effectiveness of powdered activated carbon (PAC) injection for control of mercury emissions from flue gas of coal-fired power plants. However, there has been limited modeling work accounting for the removal of mercury by existing equipment as shown by Information Collection Request (ICR) data and by PAC injection, independently of one another. ...
متن کاملAdsorption of Imidacloprid on Powdered Activated Carbon and Magnetic Activated Carbon
The adsorptive characteristics of imidacloprid on magnetic activated carbon (MAC12) in comparison to powdered activated carbon (PAC) were investigated. Adsorption of imidacloprid onto powdered activated carbon and magnetic activated carbon was studied as a function of time, initial imidacloprid concentration, temperature and pH. Pseudo-first-order, pseudo-second-order and intraparticle diffusio...
