Book Description :

To comprehend the engineered nanoparticle release to waster, soil, and air, it is important to understand the discharge from specific points of release. And as a point of release, wastewater treatment plants play a critical role in the collection and redistribution of nanoparticles in municipal waste streams. So to better understand its fate and transport, the current study focuses on three major subjects regarding the quantification, particle-particle interaction, and particle-organic sorption of engineered nanoparticles in wastewater treatment plants. ☐ To quantify engineered nanoparticles, a novel pretreatment method was developed for ICP-OES analysis. Samples were collected from various locations in the treatment plant, mainly to verify the transport pathway, and mass balance of each sedimentation basins. A concentration profile was mapped out, to visualize the distribution of engineered nanoparticles throughout the treatment plant. Additional aspects such as the mass flux, particle to organic ratio, and seasonal variations were also mapped out for further analysis. Results showed an overall 80% removal of titanium and 68% removal of zinc through primary and secondary sludge particulates, respectively, indicating the importance of activated sludge in the fate of engineered nanoparticles. Seasonal effects showed elevated amounts through summer and winter, matching the seasonal consumption patterns of nanoparticle imbedded products. ☐ To understand the mechanism behind the fate of engineered nanoparticles in the wastewater treatment plants, the next sections were focused on the interactions of the particles. The first mechanism observed, was the particle-particle interaction of nanoparticles under high concentrations of dissolved organic matter. The main purpose of the observation was to understand the transport characteristics of nanoparticles through attachment efficiency experiments. The uniqueness of the current study was the fact that experimental conditions were set to simulate field conditions, where dissolved organic matter from field-operated plants were tested under TOC concentrations that match the inflow of wastewater treatment plants. Results showed the influence of organic concentration on the stability of particles, where higher organic loading will increase the stability. The second mechanism observed was the interaction of engineered nanoparticles and wastewater sludge. Based on the distribution results in the wastewater treatment plants, particle-organic sorption experiments were conducted with primary and secondary sludge particulates. The main object was to understand the attachment of engineered nanoparticles to wastewater sludge. Sedimentation experiments were conducted to measure the attachment of both suspended materials under various conditions. Conditions such as ionic strength, organic loading, and nanoparticle compositions were tested to verify the impacts of field conditions. Results showed elevated sorption of ENP under lower organic loads, lower ionic strengths and strongly hydrophobic nanoparticles. The knowledge acquired from the current research, can be a basis for future research and policy regulations.

Book Description :

Global water demands continue to rise, especially in lieu of population growth and consequential economic and energy needs. Furthermore, global climate change has placed additional stresses on the future availability of freshwater. As a result, it is now becoming crucial to replenish water sources via drinking water and wastewater treatment. Due to advancements in nanotechnology, engineered and manufactured nanoparticles are increasingly entering water and wastewater treatment plants. In addition, naturally occurring nanoparticles can also form or exist in drinking water and wastewater treatment facilities. Therefore, to design better water treatment systems, it is important to understand how these nanoparticles will affect water chemistry as well as the efficacy of drinking water and wastewater treatment processes. This work consists of environmental perspectives of natural and engineered nanoparticle interactions in two complex aqueous environments: wastewater treatment and drinking water treatment systems. First, impacts of natural and engineered nanoparticles on wastewater treatment process efficacy were investigated in the following three systems: (1) heterogeneous iron (hydr)oxide formation on organic coated substrates, (2) homogeneous iron (hydr)oxide formation, and (3) mixed homo/heterogeneous nucleation of iron (hydr)oxide on CeO2 engineered nanoparticles. In System (1), heterogeneous precipitation of naturally occurring iron (hydr)oxide nanoparticles in model wastewater systems was investigated. Quartz, polyaspartate and alginate coated substrates were used to model abundant mineral substrates found downstream of wastewater treatment, anionic polyelectrolytes used in coagulation processes, and extracellular materials in biofilm during biochemical treatment, respectively. For the first time, iron (hydr)oxide nanoparticle formation on polymeric substrates was monitored in situ. Results indicated that substrate surface hydrophilicity was more dominant than electrostatic interactions in predicting nucleation. In System (2), homogeneous iron (hydr)oxide nucleation and phase transformation was then investigated as a function of synthesis conditions. Iron (hydr)oxides are highly reactive and effective sorbents for wastewater contaminants and formation conditions can determine their sorption efficacy. Therefore, in this study, the Fe(III) hydrolysis kinetics and cooling rates were altered to investigate the simultaneous formation of mixtures of hematite and 6-line ferrihydrite iron (hydr)oxide nanoparticles. Complementary in situ and ex situ analytical techniques revealed that understanding in situ physicochemical properties can control ex situ nanoparticle characteristics. Also, separate, distinct hematite and 6-line ferrihydrite phases were generated simultaneously and 6-line ferrihydrite removed more As(V), a model wastewater contaminant, compared to hematite. Moreover, iron (hydr)oxides can also form in the presence of engineered nanomaterials in wastewater which can affect contaminant transport downstream as well as wastewater stream chemistry. Therefore, in System (3), iron (hydr)oxide formation on engineered cerium oxide (CeO2) nanoparticles by redox reactions with Fe2+ (a reagent used in advanced oxidation processes in wastewater treatment) and Cr(VI)(aq) (a pre-existing wastewater contaminant) was investigated. The coexistence of Fe2+ and Cr(VI)(aq) were found to greatly promote the colloidal stability and to inhibit the dissolution of CeO2 nanoparticles while promoting the formation of an iron (hydr)oxide surface coating layer via redox reactions at the CeO2 nanoparticle surface. This is more prominent in the presence of Cr(VI)(aq) compared to systems without Cr(VI)(aq) ions. Engineered nanoparticles could act as heterogeneous nucleation sites and adsorption sites when released into the environment, incorporating toxic elements and molecules into a "hybrid" engineered/natural nanoparticle composite. As such, tt is essential to understand surface redox chemistry which nanoparticles could experience during wastewater treatment processes. Second, effects of naturally forming colloids and membrane-surface-modifier nanomaterials on reverse osmosis (RO) drinking water treatment processes were studied. Fouling by calcium carbonate (CaCO3) and calcium sulfate (CaSO4) and other brackish water constituents can clog RO membrane pores and reduce the amount of purified water produced, and as a result, engineered nanomaterials have been used to reduce fouling on membrane surfaces. In this work, two scientific challenges related to colloid interactions during RO were addressed: (4) mineral scaling on polyethylene glycol (PEG)-modified RO membranes, and (5) mineral scaling, organic fouling and biofouling on multifunctional membrane surfaces. In System (4), hydrophilic, polyamide RO membrane surface modification using grafted PEG was studied as a remedy to reduce fouling from mineral scalants (i.e., CaCO3 and CaSO4) and humic acid which exists in high concentrations in brackish water. In batch systems without humic acid, the PEG-grafted membranes were successful in reducing mineral scale formation at the membrane surface; however, in the presence of humic acid, a specific interaction between SO4, PEG, and humic acid resulted in promoted CaSO4 scaling at the membrane surface. Findings of this work indicate that multiple RO feed water constituents should be considered when determining the efficacy of membrane surface modifications. In System (5), to simultaneously combat colloidal fouling from CaCO3 and CaSO4, organic fouling (e.g., humic acid) and biofouling (e.g., Escherichia coli), a multifunctional membrane was fabricated. Graphene oxide (GO) nanosheets, gold nanostars (AuNS), and PEG were combined on polyamide RO membrane surfaces and demonstrated to significantly reduce fouling from the three major fouling classes. Bacterial inactivation at the RO membrane surface was achieved by irradiating the membrane with an 808 nm laser activating the photothermal properties of the Au nanostars. Our newly developed novel, multifunctional membrane surface was therefore able to significantly reduce mineral scaling, organic fouling, and biofouling during RO without additional chemical or thermal treatments. The findings from this systematic, mechanistic study investigating natural and engineered nanoparticle interactions in complex, dynamic systems can help improve the understanding of the fate, transport, and transformations of nanoparticles in water and wastewater treatment processes in response to increasing quantities and applications of nanoparticles in aquatic systems. Furthermore, through our unique engineered design, we have provided promising solutions for drastically improving water treatment processes in complex feed solutions.

Book Description :

Nanotechnology is a much talked about, and rapidly expanding area of science, which is sometimes little understood. It looks set to make a significant impact on human life and, with numerous commercial developments emerging, will become a major industry over the coming years. Nanotechnology can be broadly described as developing or exploiting products at nanometre dimensions (i.e. as having one dimension less than 100 nanometres). Such materials have a larger surface area to volume ratio than conventional materials which provides them with an increased level of reactivity, and consequently, toxicity per unit mass. This book sets the subject into context by first of all describing the current range of products containing nano-materials and then looking at the consequences for the environment and human health relating to the introduction of nanoparticles and nano-tubes. Nanotechnology: Consequences for Human Health and the Environment discusses some of the more controversial issues associated with the field including: nanoparticles in the environment, occupational exposure, toxicological properties, human health issues and safety. This authoritative and comprehensive book will be of interest to both scientists and technologists but also to regulators and government.

Book Description :

Nanotechnology has brought a large number of engineered nanomaterials and nanoparticles to applications in multiple daily products and in almost every sector of society. The many advantages that this relatively new science has brought to our daily life are evident, but still little is known on the potential environmental and human risk posed by nanotechnology applications. Particularly, the potential release into aquatic environment of these new potential pollutants raises concerns on the security of resources used for drinking water production. It can also create significant challenges to water treatment facilities in terms of operational optimization and proper process control. This thesis investigates the removal and removal mechanisms of engineered nanomaterials and nanoparticles in simulated drinking water treatment plants. It focuses on how engineered nanomaterials and nanoparticles affect process performances and which treatments are best to follow for their removal.
