Advanced Membranes for Treatment of Oily and Highly Impaired Waters LAP Lambert Academic Publishing

Książki / Literatura obcojęzyczna

The overall goal of my PhD research was to design and develop advanced anti-fouling and self-cleaning membranes for treating impaired waters. Initial work focused on the development of membranes to treat produced water, which is oily Wastewater that is co-produced during oil and gas exploration. Economical, environmentally sustainable treatment of the large volumes of produced water is a grand challenge for oil and gas companies. While membranes offer many advantages over more conventional treatment methods, membrane-based treatment processes for oily waters often fail due to membrane fouling. Therefore, the primary objective of my doctoral research was to design membranes that limit foulant accumulation and provide an easy, chemical-free way to remove any attached foulants during the filtration of oily and other impaired waters. My strategy was to modify the surface of Ultrafiltration (UF) membranes with polymer nano-layer coatings using methods that enabled nano-scale control over the chemical and environmentally responsive conformational properties of grafted polymer layers.

Riverbank Filtration for Water Security in Desert Countries Springer Netherlands

Książki / Literatura obcojęzyczna

Riverbank filtration is a low cost, yet efficient water treatment technology. It has most potential to provide safe drinking water to large cities located along rivers or lakes. In particular, it is ideal for large population centres in developing countries, where the cost of building extensive treatment facilities is prohibitive. Water filtration can be successfully implemented using naturally occurring sand and gravel along the river/lake banks. The cost of water produced by this means is much lower than that of water treated in conventional treatment plants. §Authored by a multi-disciplinary team of experts, this volume addresses the scientific basis of the filtration process, and also numerous topics of importance for the planning, technical realization, and security of such plants. Their application for the removal of relevant chemical pollutants and a variety of pathogens is analysed in detail.

Impact of UV Disinfection on Biological Stability IWA Publishing

Inne 1

Interest in UV disinfection has increased significantly in recent years, due its ability to inactivate Cryptosporidium parvum. Although UV disinfection shows significant promise for inactivation of Cryptosporidium, very few investigations have examined the impact of UV disinfection on biological stability in distribution systems. Biologically stable water is defined as drinking water that does not promote the growth of microorganisms and is typically achieved either through the removal of substrate and/or by providing a secondary disinfectant. At present there is little information concerning potential synergies between UV treatment and secondary disinfectants for improving biological stability. The overall objective of the research was to evaluate the effect that UV disinfection has on biofilm growth in drinking water distribution systems. In addition, the project's sub-objectives were to (1) determine the potential synergistic effects between primary disinfection with UV treatment and secondary disinfection for controlling bacterial regrowth; (2) compare the effectiveness of chlorine dioxide, free chlorine, and monochloramine for limiting bacterial regrowth in the presence and absence of UV treatment; (3) characterize the chemical intermediates formed during UV/CI2 photocatalysis of natural organic matter; and (4) examine the potential impact of UV/CI2 treatment on the biodegradability of natural organic matter (NOM) for three drinking water utilities. The research was conducted in three phases: Phase 1 provided a direct comparison of chlorine---based disinfectants following UV disinfection; Phase 2 examined the biodegradability of humic material that had been photocatalyzed with UVICI2; and Phase 3 characterized the organic by--products produced following UVICI2 catalysis of post-filtered water obtained from three water utilities. Phases 1 and 2 were conducted at bench-scale using annular reactors (ARs) to monitor bacterial regrowth. Phase 3 was conducted at bench-scale with a batch biodegradation study to monitor bacterial growth, by-product production, and organic degradation. During Phase 3, post--filtered water was collected from three water utilities and determination of biodegradability was completed.

Calcium Phosphates in Biological and Industrial Systems, 1 Springer, Berlin

Książki / Literatura obcojęzyczna

Research on calcium phosphates has attracted considerable attention in recent years. Calcium phosphates are the major inorganic constituents of biological hard tissues such as teeth and bones and other pathological minerals. Calcium phosphates have been widely produced in industry, in such forms as, ceramics, nutrient supplements, medicines, dentifrices, and stabilizers for plastics. They are utilized in solid state chemistry as fluorescent lamp phosphors and play a role in waste water treatment processes. Calcium phosphates are important in industrial water treatment (Le. , boiler and cooling) where deposition of these salts on heat exchanger surfaces can lead to loss of system efficiency, overheating, unscheduled shutdown time, and ultimately heat exchanger failures. Effective control of calcium phosphate deposits continue to challenge the industrial scientist. Calcium phosphate deposits have also been encountered during pasteurization of milk. Calcium phosphates of interest include: dicalcium phosphate dihydrate (DCPD, CaHP0-2H0), brushite; dicalcium phosphate anhydrous (DCP, CaHP0), 4 2 4 monetite; octacalcium phosphate (OCP, CasH2(P04)6-SH20); tricalcium phosphate (TCP, Ca3(P04h), whitlockite; and hydroxyapatite (HAP, Cas(P04h0H). Other calcium compounds of biological and industrial interest include: amorphous calcium phosphate (ACP); fluorapatite (FAP, CaS(P04)~); calcium pyrophosphate dihydrate (CPPD, CaP07-2H0); calcium fluoride; and calcium phosphonates. 2 2 2 This book is intended to provide a comprehensive discussion on calcium phosphates in the diverse areas of their investigations.

Alkyl Aryl Sulfonates LAP Lambert Academic Publishing

Książki / Literatura obcojęzyczna

Alkyl aryl sulfonates is the largest in quantity among all surfactants produced. Their importance lies in its power of reducing oil-water interfacial tension. They have wide applications based on their functional properties, i.e., de- emulsification & de-emulsification, dispersion, wetting, solubilization, inhibition of rust and corrosion. Petroleum sulfonates originally were produced as by-products of petroleum refining. But refineries are now adopting solvent extraction in place of acid treatment and petroleum sulfonate is no more available as by-product. In the search of alternatives, scientists are working on different source and molecular design. Aimed at the ultimate design and development of suitable sulfonates for a particular application, extensive studies were initiated regarding the effect of structural parameter on their surface-active properties. In this connection, several alkyl aryl sulfonates have been synthesized having different structures in aromatic portion and evaluated for their surface-active, micellar, hydrodynamic, thermodynamic, detergency and solubilization properties to establish a correlation between the structural parameters and these properties.

Solar Hydrogen Royal Society Of Chemistry

Książki / Literatura obcojęzyczna

Renewable hydrogen produced using solar energy to split water is the energy fuel of the future. Accelerated innovation in both major domains of solar energy (photovoltaics and concentrated solar power) has resulted in the rapid fall of the solar electricity price, opening the route to a number of practical applications using solar H2. New thermochemical water splitting using concentrated solar power (CSP) as well as CSP coupled to electrolysis has the potential to convert and store solar energy into clean hydrogen using a tiny fraction of the world's desert area to meet our present and future global energy needs. Photovoltaics, in turn, has the versatility required for supporting the creation of a distributed energy generation infrastructure in developing countries especially now that the price of PV solar electricity has fallen to unprecedented low levels. In all these cases, solar H2 will be used to store energy and release it on demand either for fuel cells (to power homes and boats) or internal combustion engines and turbines (for powering cars, trucks and in thermoelectric power units). This book on solar hydrogen is unique in its field and is a timely treatment of a hot topic in industry, academic, political and environmental circles. With reference to many examples as well as to new technologies, this accessible book provides insight into a crucial technology for our common future and numerous colour pictures contribute to the book's readability. Written by experts in the field who are engaged at the forefront of research, the book supplies readers with last minute insight from the frontiers of research. The book will be of interest to Politicians, solar PV companies, hydrogen and sustainability researchers, environmentalists, managers in the automotive and nautical industries, undergraduate and graduate students in physics, chemistry, energy and materials science.

Production of biodiesel using lipase encapsulated in -carrageenan, 1 Springer, Berlin

Książki / Literatura obcojęzyczna

This book explores a novel technique for processing biodiesel using lipase immobilization by encapsulation and its physical properties, stability characteristics, and application in stirred tank and re-circulated packed bed immobilized reactors for biodiesel production. The enzymatic processing of biodiesel addresses many of the problems associated with chemical processing. It requires only moderate operating conditions and yields a high-quality product with a high level of conversion and the life cycle assessment of enzymatic biodiesel production has more favourable environmental consequences. The chemical processing problems of waste water treatment are lessened and soap formation is not an issue, meaning that waste oil with higher FFA can be used as the feedstock. The byproduct glycerol does not require any purification and it can be sold at higher price. However, soluble enzymatic processing is not perfect. It is costly, the enzyme cannot be recycled and its removal from the product is difficult. For these reasons, immobilized enzymatic process has been developed which retains the advantages of the soluble enzymatic process and reuse of the enzyme is possible which decreases the enzyme cost, the biodiesel produced does not contain any enzyme residue and the activity of the enzyme can be increased by immobilization. The drawbacks of the immobilized enzyme process are mass transfer limitation, enzyme leakage, the lack of a versatile commercial immobilized enzyme and some of immobilization methods involve toxic chemicals. To overcome the drawbacks of the immobilized enzyme, an attempt is made to use a degradable biopolymer ( -carrageenan) as a carrier for lipase immobilization.
