Application of image processing on struvite recovery from swine wastewater by using the fluidized bed

Fluidized granulation is one of the common methods used in wastewater treatment and resource recovery with harvesting millimeter-scale large particles. Presently, effective methods are lacking to measure the fluidized granules ranging from micro- to millimeter scales, with the consequence of ineffectively controlling and optimizing the granulation process. In this work, recovering struvite ...

Metals and bacteria partitioning to various size particles in Ballona Creek storm water runoff

Many storm water best management practice (BMP) devices function primarily by capturing particulate matter to take advantage of the well‐documented association between storm water particles and pollutants. The hydrodynamic separation or settling methods used by most BMP devices are most effective at capturing medium to large particles; however, these may not be the most predominant particles ...

Adsorption characteristic of As(III) on goethite waste generated from hydrometallurgy of zinc

In this paper, goethite waste from hydrometallurgy of zinc was used as a raw material for arsenic adsorbent preparation. The goethite waste adsorbent (GWA) was characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), and particle size distribution analysis. The adsorption of As(III) on GWA was studied as a function of contact time, pH, and coexisting anions. The ...

Hydraulics stability of compost-based filtration media

The longevity of compost-based storm water filtration systems has not been widely studied. Hydraulic conductivity measurements of compost amended sand media (20% and 50% v/v) within columns were undertaken. The results show that the filtration media in both columns had a reduction in the total saturated hydraulic conductivity. A tracer test showed there was no blockage due to biological or ...

Fine particle capture in biomass boilers with recirculating gas cyclones: Theory and practice

This paper addresses the theoretical development and experimental validation of optimized recirculating reverse-flow gas cyclones. The simulation of these systems is based on the predictive properties of a finite diffusivity model, modified to include partial recirculation of the cyclones' emissions. Experimental validation was obtained at laboratory and pilot scales at low temperatures (up to ...

The role of settling velocity formulation in the determination of gully pot trapping efficiency: comparison between analytical and experimental data

Roadside gully pots are the connecting points between surface runoff and the underground drainage network; therefore they can be considered as the most superficial component of urban drainage systems. Gully pots are supposed to trap particulate matter washed off the catchment surface, but also to collect and convey stormwater into the network. The continuous accumulation of particulate matter ...

Clean your test sieves to maintain accurate results

A standard process in analytical laboratories is sieve analysis, the practice of accessing the particle size distribution of a granular material. The trouble is, sieves prove quite the challenge to clean thoroughly enough to get all the contaminants out of the mesh. Every last grain stuck in the sieve must be removed to gain accurate analysis. A solution has been found in the use of ultrasonic ...

An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

Effects of current density on copper nanoparticle prepared by electrochemical method

Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...

Characterization and biodegradability of sludge from a high rate A-stage contact tank and B-stage membrane bioreactor of a pilot-scale AB system treating municipal wastewaters

In light of global warming mitigation efforts, increasing sludge disposal costs, and need for reduction in the carbon footprint of wastewater treatment plants, innovation in treatment technology has been tailored towards energy self-sufficiency. The AB process is a promising technology for achieving maximal energy recovery from wastewaters with minimum energy expenditure and therefore ...

Tailing propensity in the ultraviolet disinfection of trickling filter and activated sludge wastewater treatment processes

In this paper, the effect of suspended flocs on the tailing of ultraviolet (UV) disinfection kinetics of secondary effluents was examined. To achieve this goal, final effluents produced in two processes for treating wastewater; namely, a trickling filter system and an activated sludge system, were collected and their UV disinfection were compared. Tailing of the UV dose response curve was ...

Impact of agricultural activities on phosphorus in streams draining into Opa Reservoir Ile Ife, Nigeria

Phosphorus is noted as the limiting factor of eutrophication. We investigated the impact of different agricultural land use (mixed cropping, horticultural garden and fallow land) on the phosphorus loading of a reservoir. Soil samples were analysed for pH, particle size distribution, organic matter, available P and erodibility index calculated. Water samples analysed for biological oxygen demand ...

Pegasor Mi3 - Background - Particle size is not well defined

Fine and nanoparticles can be defined in many ways. Especially when defining the particle size and concentration. Particle size can be measured either off-line or on-line. Off line techniques typically give out particle filter mass concentration. Off-line techniques are seldom used to define particle size. When this is done, electron microscopy is typically used to measure particle geometric ...

Monitoring nanoparticles in the presence of larger particles in liquids using acoustics and electron microscopy

Monitoring the presence of nanoparticles in dispersions having broad particle size distributions can be a problem for many measurement techniques because large particles or even aggregates of the smaller particles can mask the presence of the sought after nanoparticles. The ability of many existing techniques to detect the nanoparticles when present in broad polydisperse systems is largely ...

Particulate polycyclic aromatic hydrocarbons in urban air of Tehran

Epidemiological studies have shown correlations between the concentration of particles in the air and increase of daily rates of respiratory and cardiovascular diseases and mortality (Douglas et al.,1992; Jonathan et al.,1995; Auron et al.,1995). Elevated lung cancer rates among women in rural china have been attributed to emissions from their coal-fired stoves (Mumford et al.,1987;Alder and ...
