Abstract:

Applying chemical coagulants and auxiliary coagulants in wastewater treatment has become more popular in Vietnam. Although the efficacy of chemical coagulants has been well recognized, there are disadvantages associated with the use of these products, such as the inefficiency at low temperatures, increasing the residual cation in solution, causing health problems and distribution water, relatively high cost, producing high volume of sludge. Thus, it is desirable to replace these chemical coagulants for products that do not generate such drawbacks, such as natural polymers. In this paper, the a

Abstract:

A combinação de coagulação/floculação/sedimentação, filtração lenta em escala domiciliar e adsorção foi ponderada como alternativa de tratamento de águas com Microcystis aeruginosa e microcistina para comunidades isoladas. As Cactáceas Opuntia cochenillifera e Opuntia ficus-indica foram estudadas como coagulantes e a espécie Luffa cylindrica foi estudada como adsorvente. Os coagulantes foram avaliados em ensaios em bancada com água contendo M. aeruginosa. O extrato de O. cochenillifera apresentou melhor desempenho por isso foi selecionado para ensaios de bancada em jarteste seguidos por filtra

Abstract:

This doctoral thesis involves two components, a book length collection of poems and a critical study of ‘Herbert White’ and ‘Ellen West’ by Frank Bidart. The collection of poems, The Coagulate, consists of four parts: 1) Semi-personal poems focusing on nature both in a general sense and in specific reference to the natural British landscape. 2) Poems that explore the nature-based myths and contemporary social idiosyncrasies of Japan.3) Poems that explore the social perception of mental illness and the individual voices that exist in spite psychological classification.4) Poems by an alter-ego a

But along this treatment significant amount of sludge are generated contains organic material and nutrients that have agriculture value. For the sludge recovery it should be treated to reduce the water volume before being disposed in the land. In this process generally we use chemicals such as polymers for the sludge dewatering but these products are expensive and can damage our envir

碩士<br>國立成功大學<br>環境工程學系<br>107<br>This study was aimed to examine the applicability of using a natural coagulant extracted from the seeds of a tree, Moringa Oleifera cationic protein (MOCP), for the control of cyanobacterial blooms in lakes and reservoirs. A fast protein liquid chromatography (FPLC) was combined with cation exchange resins to purify MOCP and to improve the coagulation efficiency. The laboratory experimental results of cyanobacterial removal show that MOCP achieved better efficiency for the Cylindrospermopsis raciborskii than Microcystis aeruginosa, and the reduction of cylindro

Abstract:

碩士<br>國立交通大學<br>環境工程系所<br>99<br>The zeta potential of coagulated particles is commonly used as an index to evaluate the optimal dosage of coagulation in water treatment. However, the qualities of raw water taken from surface turbid water by water treatment plant (WTP) fluctuates immensely, resulting in variation of optimal zeta potential zone for coagulation of different natural turbid water. Therefore, there are still many debates on determination of the optimal dosage through the indication of zeta potential. The goal of this study is to investigate the relationship between optimal dosage an

Abstract:

Solar water disinfection (SODIS) is the process of treating microbiologically contaminated water in clear plastic bottles through exposure to sunlight. One of the major limiting factors of this treatment is source water quality. This work investigates the impact of organic matter and turbidity on SODIS efficiency. Organic matter was found to decrease bacterial inactivation to a much greater extent than the presence of inorganic particles. The ability of moringa oleifera seed emulsion to clarify source waters was investigated as a coagulation pretreatment. This coagulant is most effective in hi

However, the turbidity of raw water is highly varied with time. Sometimes, low turbidity-containing raw water was treated with iron-based coagulants or dual dosing with PACl and FeCl3 coagulants to allow the residual aluminum in finished water comply with drinking water quality standards. The purpose of this study is to investigate FeCl3 and PACl alone add into raw water or combination, which type can be effectively reduce residual dissolve

Abstract:

Over the past decade, the objectives for coagulation based drinking water treatment processes have changed significantly. These changes are a result of stringent goals related to natural organic matter (NOM) removal to mitigate the formation of subsequent harmful and health-related disinfection by-products (DBPs) and the need to achieve adequate filtration performance to ensure sufficient particle removal for pathogen control. Another concern associated with coagulation optimization is the potential unintended consequences of a coagulant change on the distribution system, specifically relate
