Existing heavy metals promoted aggregation and deposition of dissolved black carbon, which was related to the physicochemical properties metal cations.
The cations decreased the deposition kinetics of different charged NPs onto silica with decrease in hydration degree additive cations.
The influence of ionic strength on the transport behaviors natural or engineered colloids has been widely studied in recent years, and explanatory classical Derjaguin–Landau–Verwey–Overbeek (DLVO) theory also employed many studies. However, ion-specific effects were barely applied to interpret contradiction between experimental observations DLVO predictions when nanoparticle colloidal aggregation deposition took place different cationic solutions. In this study, specificity first-group...
ABSTRACT: In this study, FLUENT software was used to simulate the flow regime of an integrated sludge thickening and digestion reactor. To optimize regime, combinational effect key parameters reactor structure investigated with L 16 (4 5 ) orthogonal test. The then redesigned based on optimization results, a series experiments conducted study treatment dosage rates 12, 18, 24, 30%. operation results showed that obtained best efficiency when rate 24%. At dosage, water content decreased from...
The extracellular polymeric substances (EPS) from activated sludge played significant roles in the removal of nanoparticles wastewater. A series batch experiments were carried out to determine adsorption mechanism three nano-Ag by sludge, as well contributions EPS fractions including dissolved (DEPS), loosely bound (LB-EPS) and tightly (TB-EPS). results demonstrated that biomass agreed with pseudo second order kinetic reaction model Freundlich isotherm model. About 26.0-41.2 % was trapped...
A Co-operation Waste Water Treatment Plants (CWWTPs) model is introduced to solve such problems as dispersed locations, small scale, funds shortage and difficult management in Plants(WWTPs) of towns. In this model, a main plant can drive other subsidiary plants cooperate then, show higher efficiency less operation costs. To affirm the economic benefit CooperationWasteWater towns, cost computing foundered compare targets labor cost, purchase construction etc. that traditional mode. It be used...
