Water quality characterization in real biofilm wastewater treatment systems by particle size distribution

A critical review on characterization strategies of organic matter for wastewater and water treatment processes

“…Usually, the variation of PSD in a WWTP can be dependent on the nature of the suspended solids in the influent wastewater. Previous studies have reported that the PSD of OM can directly affect its biodegradability (Dulekgurgen et al, 2006;Garcia-Mesa et al, 2010). The small size OM can be consumed by microorganisms easily since smaller particle size increases the surface area available to the microorganisms, while larger particles need to be hydrolysed prior to consumption (Dimock and Morgenroth, 2006;Karahan et al, 2008).…”

Filtering capacity of Daphnia magna on sludge particles in treated wastewater

“…Technologies based on biofiltration and precoagulation have been evaluated with the purpose to obtain an easy and low cost maintenance of the wastewater cleaning process (Hidaka et al, 2003). The methods for evaluation are based on the particle analysis, whether it is the particle content, concentration or size distribution (García-Mesa et al, 2010). Particle content in wastewaters is an important parameter for the evaluation of chemical, physical and biological treatments (Marquet et al, 2007).…”

“…Wu et al (2009) studied the relationship between the particle size distribution and suspended solids, turbidity and microorganisms and they proposed the continuous analysis of the particle size distribution to evaluate the water quality of the effluent. García-Mesa et al (2010) characterized the water quality of different wastewater treatments by means of the analysis of the particle size distribution. Based on the reduction in the particle concentration for different particle sizes they were able to analyze the performance of three biofilm technologies.…”

The hydraulic retention time on the particle removal efficiency by Daphnia magna filtration on treated wastewater

“…Chavez et al (2004) used particle size distribution to evaluate the microbial quality of wastewater. Particle size distribution was also used by Marquet et al (2007) to characterize trickling filter effluent and by García-Mesa et al (2010) to compare the water quality of effluent from different treatments: a submerged biofilm, a trickling filter and a rotating biological contactor. Daphnia filtration has also been found to be an efficient technique in removing emergent contaminants from wastewater (Matamoros et al 2012).…”
