Organic and microbial contaminants of emerging concern (CECs), even though not yet regulated, are great in reclaimed water reuse projects. Due to the large number CECs their different characteristics, it is useful include only a limited them monitoring programs. The selection most representative still current open question. This study presents new methodology for this scope, particular evaluation performance polishing treatment assessment risk environment irrigated crops. As organic CECs,...
This work provides a screening of organic contaminants and characterization the dissolved matter in sewer network until municipal wastewater treatment plant (WWTP), identifying areas with higher degree contamination their impact on WWTP performance, particularly activated sludge reactor. Three monitoring campaigns were carried out at six selected locations sewage system (PVZ-1, PVZ-2, PS-F, PS-VC, CP-VC, PS-T), influent (WWTPINF) effluent (WWTPEFF) WWTP. Advanced analytical techniques...
A tubular porous borosilicate membrane contactor was investigated for ozone gas/water mass transfer and the removal of contaminants emerging concern (CECs) in water. Ozone contact occurs on shell-side, which is coated with a photocatalyst (TiO2-P25), as gas stream fed from lumen side permeates through pores generating micro-sized bubbles uniformly delivered to annular reaction zone where contaminated water be treated flows. Under continuous flow, pH at 3.0 temperature 20 ºC, volumetric...
A tubular membrane photoreactor, operated in continuous mode and low residence times (τ from 3.9 to 12.2 s), was applied for the removal of 14 antibiotics (sulfonamides, fluoroquinolones, macrolides, cephalexin, trimethoprim) demineralized water (DW) secondary-treated urban wastewater (UWW). In this setup, oxidant (hydrogen peroxide (H2O2), persulfate (S2O82−) or ozone (O3)) is permeated through pores delivered catalyst (titanium dioxide (TiO2) silver molybdate (Ag2MoO4)), embedded shell...
As global effects of water scarcity raise concerns and environmental regulations evolve, contemporary wastewater treatment plants (WWTPs) face the challenge effectively removing a diverse range contaminants emerging concern (CECs) from municipal effluents. This study focuses on assessment advanced oxidation processes (AOPs), specifically UV-C/H
A membrane ozone contactor, operated under continuous mode, was applied to promote the tertiary treatment of urban wastewater (UWW), targeting removal contaminants emerging concern (CECs), bacterial disinfection, and toxicity reduction. This system relies on homogeneous radial distribution (O3) in reaction zone by "titration" through a microfiltration borosilicate tubular membrane, while UWW swirls around drags O3 microbubbles generated shell-side. The is coated with titanium dioxide...
A treatment train for the remediation of a raw olive mill wastewater (OMW) was investigated, aiming to comply with emission limit values (ELVs) direct discharge into water bodies. The following stages were proposed: (i) pre-treatment (filtration and sedimentation), (ii) coagulation, (iii) biological oxidation, (iv) advanced oxidation process (AOP). Under best-operating conditions coagulation (0.8 g L−1 Al2(SO4)3, pH = 4.5), high removal total suspended solids (TSS) (97%), turbidity (98%),...
Photoactivated advanced oxidation processes have excellent performance in removing recalcitrant pollutants from water. However, the high operating cost associated with energy consumption of UV lamps is a big drawback. In this work, design and optimization reflector tube-in-tube membrane photoreactor were carried out using ray tracing methodology to maximize light deployed reactor. Simulations different lamps/reactor arrangements 1, 2 3-sided flat reflectors circular parabolic geometries....
Photo-Fenton (PF) is a promising process for degrading wide range of contaminants emerging concern (CECs) present in urban wastewater (UWW) after secondary treatment, mitigating their spread aquatic systems. However, the near-neutral pH UWW poses challenge to PF performance. In this research, tubular membrane photoreactor, designed continuous "titration" Fe2+, explored promote tertiary treatment UWW. The application persulfate (PF-like) as an alternative oxidant and impact phosphate (PO43−)...
The ecotoxicological response of the living organisms in an aquatic system depends on physical, chemical and bacteriological variables, as well interactions between them. An important challenge to scientists is understand interaction behaviour factors involved a multidimensional process such response. With this aim, multiple linear regression (MLR) principal component were applied ecotoxicity bioassay Chlorella vulgaris Vibrio fischeri water collected at seven sites Leça river during five...
ABSTRACT Caprolactam and o ‐ p ‐toluenesulfonamide are tested as chain‐growth blockers for melamine–urea–formaldehyde (MUF) resins, in an attempt to reduce the crosslinking density of cured resin hence improve its flexibility. Agglomerated cork panels, which flexibility is a technical demand, were produced with modified resins tested. The added at three different steps synthesis process: methylolation, condensation, end synthesis. Besides evaluation standard properties, characterized using...
