การบำบัดน้ำเสียปนเปื้อนน้ำมันตัดด้วยกระบวนการโฟโตเฟนตัน, สุทธิชา ปัญญาเกิด

Chulalongkorn University Theses and Dissertations (Chula ETD)

น้ำมันตัดเป็นน้ำมันที่ใช้ในการลดแรงเสียดทานและระบายความร้อนของชิ้นงานในกระบวนการผลิต น้ำมันตัดที่ผ่านการใช้งานแล้วจะมีค่าซีโอดี ความขุ่น และของแข็งแขวนลอยสูง นอกจากนี้ยังมีส่วนประกอบของสารลดแรงตึงผิว ทำให้น้ำเสียปนเปื้อนน้ำมันตัดมีลักษณะเป็นอิมัลชันที่มีความคงตัวสูงและยากในการบำบัดด้วยกระบวนการทางชีวภาพและกายภาพทั่วไป ในงานวิจัยนี้ได้ทำการศึกษาประสิทธิภาพและสภาวะที่เหมาะสมของการบำบัดน้ำเสียปนเปื้อนน้ำมันตัดความเข้มข้นต่ำที่ไม่สามารถบำบัดได้หมดจากกระบวนการขั้นต้นและน้ำเสียปนเปื้อนน้ำมันตัดความเข้มข้นสูงที่มีค่าใกล้เคียงกับความเข้มข้นของน้ำมันตัดที่เหลือจากการใช้งานในกระบวนการจริงด้วยกระบวนการเฟนตันและโฟโตเฟนตัน ในงานวิจัยนี้ศึกษาความเข้มข้นของน้ำมันตัดเริ่มต้น 0.1 1.0 4.0 9.0 และ 22.0 กรัมต่อลิตร โดยใช้เฟอร์รัสซัลเฟตเป็นตัวเร่งปฏิกิริยาและควบคุมพีเอชที่ 3.0 ± 0.2 จากการศึกษาประสิทธิภาพการบำบัดน้ำเสียปนเปื้อนน้ำมันตัดความเข้มข้น 0.1 และ 1.0 กรัมต่อลิตร โดยใช้เฟอร์รัสไอออน 50 มิลลิกรัมต่อลิตร และอัตราส่วนของเฟอร์รัสไอออนต่อสารละลายไฮโดรเจนเปอร์ออกไซด์ที่ 1: 2.5 ด้วยกระบวนการเฟนตัน พบว่าสามารถบำบัดซีโอดีได้ร้อยละ 88.97 ± 5.63 และ 91.98 ± 1.68 ตามลำดับ เมื่อทำการบำบัดด้วยกระบวนการโฟโตเฟนตันพบว่าอัตราส่วนของเฟอร์รัสไอออนต่อสารละลายไฮโดรเจนเปอร์ออกไซด์ที่ 1: 10 มีประสิทธิภาพในการบำบัดซีโอดีของน้ำเสียปนเปื้อนน้ำมันตัดทั้งสองความเข้มข้นได้สูงสุดร้อยละ 96.21 ± 5.23 และ 91.95 ± 1.52 ตามลำดับ เมื่อทำการบำบัดน้ำเสียปนเปื้อนน้ำมันตัดความเข้มข้นสูงที่ 4.0 9.0 และ 22.0 กรัมต่อลิตร โดยใช้ความเข้มข้นของเฟอร์รัสไอออน 75 150 และ 300 มิลลิกรัมต่อลิตร และสารละลายไฮโดรเจนเปอร์ออกไซด์ 375 300 และ 1500 มิลลิกรัมต่อลิตร ตามลำดับ พบว่าสามารถบำบัดซีโอดีได้มากกว่าร้อยละ 87 โดยประสิทธิภาพการบำบัดซีโอดีของกระบวนการเฟนตันและโฟโตเฟนตันไม่มีความแตกต่างกันอย่างมีนัยสำคัญ (ระดับความเชื่อมั่น 95%) เนื่องจากในการศึกษาครั้งนี้ใช้น้ำเสียสังเคราะห์ที่มีความขุ่นสูง ทำให้บดบังแสงอัลตราไวโอเลตระหว่างการบำบัด ส่งผลให้การเพิ่มแสงอัลตราไวโอเลตไม่มีผลต่อการบำบัดน้ำเสียปนเปื้อนน้ำมันตัด รวมถึงศึกษาการนำตะกอนจากกระบวนการเฟนตันและโฟโตเฟนตันกลับมาใช้ในการบำบัดน้ำเสียปนเปื้อนน้ำมันตัดใหม่ จากผลการศึกษาพบว่าสามารถนำตะกอนกลับมาใช้เป็นตัวเร่งปฏิกิริยาแทนการเติมเฟอร์รัสไอออนในระบบได้จำนวน 2 ครั้ง โดยตะกอนที่นำกลับมาใช้ซ้ำนั้นจะมีการสะสมของสารอินทรีย์และอนุภาคของน้ำมันตัดในตะกอนเพิ่มขึ้นจากการบำบัดครั้งก่อน ทำให้มีความเข้มข้นของสารอินทรีย์เพิ่มสูงขึ้นตามรอบการใช้ตะกอนซ้ำ ส่งผลให้มีประสิทธิภาพการบำบัดซีโอดีลดลงตามจำนวนรอบการบำบัด

Effects Of Microplastic Accumulation On Floc Characteristics And Fouling Mechanism In Sequencing Batch Membrane Bioreactor, Thitiwut Maliwan

Chulalongkorn University Theses and Dissertations (Chula ETD)

This research investigated the effects of microplastic accumulation on the floc characteristics and mechanism of membrane fouling in a sequencing batch membrane bioreactor (SB-MBR). At first, the jar test experiment was performed for 120 min. The results indicate that spiking microplastics of 100-1,000 MPs/L resulted in an increase in floc size by 27.9±9.2% to 70.9±5.1%, while the control set (without microplastic) showed a greater increase in the floc size at 113.3±5.6% of the initial floc size. Afterwards, the SB-MBR, which was equipped with a flat-sheet microfiltration membrane, was operated at 24 hours/cycle with 4 reactors at the influent COD of …

New Biotechnological Approaches To Insect Pest Management And Crop Protection; Gene Editing Approach (Crispr-Cas System)., Anastacia Books

Department of Entomology: Distance Master of Science Projects

Since its introduction into the Integrated Pest Management (IPM) program over 20 years ago, the biotechnological approach for insect pest management, starting with transgenic Bacillus thuringiensis (Bt), appeared to have revolutionized the concept of genetic manipulation approach in insect pest management and crop protection. Transgenic (Bt) crops have offered great benefits in insect management for crop protection but soon after its implementation, the technology started facing the major issue of insect resistance, leading researchers to start pursuing advancements in newer biotechnological approaches to insect pest management, such as Gene Editing (the RNA interference (RNAi); Gene Drives …

High School Arthropod Display Case, Daniel Taylor

Department of Entomology: Distance Master of Science Projects

Background: I teach at a high school in Northfield, Minnesota. I love teaching kids science and getting them excited about it. Unfortunately, I currently only teach chemistry and there are almost no elective science classes at our high school. I would love to get students interested in learning about entomology with me or on their own. Few students have ever been exposed to insect in a positive light ever before.

I have had some success at our school with entomological engagement. Each year during the zoology unit I go in to the biology classes as a “guest lecturer” and give …

Knob-Socket Investigation Of Stability And Specificity In Alpha-Helical Secondary And Quaternary Packing Structure, Taylor Renee Rabara

University of the Pacific Theses and Dissertations

The novel knob-socket (KS) model provides a construct to interpret and analyze the direct contributions of amino acid residues to the stability in α-helical protein structures. Based on residue preferences derived from a set of protein structures, the KS construct characterizes intra- and inter-helical packing into regular patterns of simple motifs. The KS model was used in the de novo design of an α-helical homodimer, KSα1.1. Using site-directed mutagenesis, KSα1.1 point mutants were designed to selectively increase and decrease stability by relating KS propensities with changes to α-helical structure. This study suggests that the sockets from the KS Model can …

Functional Analysis Of Bacillus Anthracis Aspartate Transcarbamoylase And Dihydroorotase, Katelyn Leigh Schwager Silva

Wayne State University Theses

There are many enzymes required for efficient and proper pyrimidine biosynthesis. The two that are most important and were discussed in this thesis are aspartate transcarbamoylase (ATCase) and dihydroorotase (DHOase). Both play an important role in not only pyrimidine biosynthesis production, but also mechanistic regulation of de novo synthesis. Anthrax is an infection caused by Bacillus anthracis. Here we studied ATCase and DHOase in Bacillus Anthracis. In this thesis we understood the effects of the enzymes ATCase and DHOase on pyrimidine biosynthesis. Adequate inhibitors of these enzymes would result in cell death and could pose as a cure to infection …

Social And Psychological Factors Affecting Coping With And Adjusting To Disability, Alie Kriofske Mainella, Susan Miller Smedema

College of Education Faculty Research and Publications

This chapter provides an overview of the social and psychological factors contributing to coping with and adjusting to disability by summarizing models; clinical implications, evidence-based practice, and measurement issues; and empirical research related to the process of coping with and adjustment to disability. While the models are useful for understanding a portion of the experience of people with disabilities and their coping and adjustment process, these reactions are not universal and not always experienced in an orderly sequence. Both coping and adaptation are multidimensional, complex processes affected by many factors and influenced by the person with the disability, the stress …

An Evolutionary Theory Of Administrative Law, Karrigan S. Bork

SMU Law Review

Law evolves to accommodate change—this is axiomatic in most academic legal traditions. But in the era of the administrative state, with congressional gridlock and a judiciary hesitant to address policy questions, evolution of statutory law has become much more difficult. This leads to pent up demand for change in legal regimes. If the legislature and the courts cannot provide an outlet for this pressure, where does it go? How does the law continue to change? Although other scholars have looked to agencies as engines of legal change, we lack a theoretical framework to understand how that change happens. I argue …

Antidiscriminatory Privacy, Ignacio Cofone

SMU Law Review

Law often blocks sensitive personal information to prevent discrimination. It does so, however, without a theory or framework to determine when doing so is warranted. As a result, these measures produce mixed results. This article offers a theoretical framework for determining, with a view of preventing discrimination, when personal information should flow and when it should not. It examines the relationship between precluded personal information, such as race, and the proxies for precluded information, such as names and zip codes. It proposes that the success of these measures depends on what types of proxies exist for the information blocked and …

Msg-Fast: Metagenomic Shotgun Data Fast Annotation Using Microbial Gene Catalogs, Stuart M. Brown, Hao Chen, Yuhan Hao, Bobby P. Laungani, Thahmina A. Ali, Changsu Dong, Carlos Lijeron, Baekdoo Kim, Claudia Wultsch, Zhiheng Pei, Konstantinos Krampis

Publications and Research

Background: Current methods used for annotating metagenomics shotgun sequencing (MGS) data rely on a computationally intensive and low-stringency approach of mapping each read to a generic database of proteins or reference microbial genomes.

Results: We developed MGS-Fast, an analysis approach for shotgun whole-genome metagenomic data utilizing Bowtie2 DNA-DNA alignment of reads that is an alternative to using the integrated catalog of reference genes database of well-annotated genes compiled from human microbiome data. This method is rapid and provides high-stringency matches (>90% DNA sequence identity) of the metagenomics reads to genes with annotated functions. We demonstrate the use of this …

A Comparative Study Of Equine Gut Microbiomes Using 16s And 18s Rrna Sequencing, Jillian Jorgenson

Undergraduate Honors Thesis Projects

The gut microbiome of domestic horses (Equus ferus caballus) can be broken down into two primary divisions of interest: (1) prokaryotic composition, consisting of bacteria and archaea and (2) fungal composition. Within the gut, there are also eukaryotic parasite communities that may interact with the microbiome. While each has been the subject of various scientific explorations, in this study we analyze the potential interconnectedness of these categories. To determine the extent to which each component of the gut microbiome/parasitic communities influences the other, DNA was extracted and amplified from the fecal samples of eight horses. A combination of …

Diagnosis Of Schistosoma Mansoni Infections: What Are The Choices In Brazilian Low-Endemic Areas?, Vanessa Silva-Moraes, Lisa M. Shollenberger, Liliane Maria Vidal Siqueira, William Castro-Borges, Donald A. Harn, Rafaella Fortini Queiroz E. Grenfell, Ana Lucia Teles Rabello, Paulo Marcos Zech Coelho

Biological Sciences Faculty Publications

The population of Brazil is currently characterised by many individuals harbouring low-intensity Schistosoma mansoni infections. The Kato-Katz technique is the diagnostic method recommended by the World Health Organization (WHO) to assess these infections, but this method is not sensitive enough in the context of low egg excretion. In this regard, potential alternatives are being employed to overcome the limits of the Kato-Katz technique. In the present review, we evaluated the performance of parasitological and immunological approaches adopted in Brazilian areas. Currently, the diagnostic choices involve a combination of strategies, including the utilisation of antibody methods to screen individuals and then …

Medical Papers and Journal Articles

Summary: In this prospective cohort of 6120 participants aged 50+, nitrogen-bisphosphonates but not non-nitrogen bisphosphonates were associated with a significant 34% mortality risk reduction compared to non-treated propensity score matched controls. These findings open new avenues for research into mechanistic pathways.

Introduction: Emerging evidence suggests that bisphosphonates (BP), first-line treatment of osteoporosis, are associated with reduced risks for all-cause mortality. This study aimed to determine the association between different BP types and mortality risk in participants with or without a fracture.

Methods: A prospective cohort study of users of different BPs matched to non-users by propensity score (age, gender, co-morbidities, …

Microsimulation Model For The Health Economic Evaluation Of Osteoporosis Interventions: Study Protocol, Lei Si, John A. Eisman, Tania Winzenberg, Kerrie M. Sanders, Jacqueline R. Center, Tuan V. Nguyen, Andrew J. Palmer

Medical Papers and Journal Articles

Introduction: Osteoporosis is a systemic skeletal disease that is characterised by reduced bone strength and increased fracture risk. Osteoporosis-related fractures impose enormous disease and economic burden to the society. Although many treatments and health interventions are proven effective to prevent fractures, health economic evaluation adds evidence to their economic merits. Computer simulation modelling is a useful approach to extrapolate clinical and economic outcomes from clinical trials and it is increasingly used in health economic evaluation. Many osteoporosis health economic models have been developed in the past decades; however, they are limited to academic use and there are no publicly accessible …

Bioethics In The News: The Values At Stake. Why Are Conservative Values So Difficult To Communicate In The Public Square And Progressive Values So Easy?, Margaret Somerville

Medical Papers and Journal Articles

Bioethical issues are complex, often involve factual uncertainty, and have broad and long-term potential consequences for individuals, institutions and society. Simplification is a strategy used by so-called ‘progressive’ values advocates to promote acceptance of their values. It results from excluding consideration of complexity, uncertainty and potentiality in the values disputes around bio-ethical issues. In order to engage effectively in public debates of bioethics issues, it is necessary to understand the current societal values zeitgeist and how it differs from a traditional societal values zeitgeist. Since words are weapons in the values battles, it is necessary to identify how they are …

Kbg Syndrome Presenting With Brachydactyly Type E, Renata Libianto, Kathy H.C Wu, Sophie Devery, John A. Eisman, Jackie R. Center

Medical Papers and Journal Articles

We report the case of a young woman who presented at age 10 years with height on the tenth centile, brachydactyly type E and mild developmental delay. Biochemistry and hormonal profiles were normal. Differential diagnoses considered included Albright hereditary osteodystrophy without hormone resistance (a.k.a pseudopseudohypoparathyroidism), 2q37 microdeletion syndrome and acrodysostosis. She had a normal karyotype and normal FISH of 2q37. Whole genome sequencing (WGS) identified a mutation in the ANKRD11 gene associated with KBG syndrome. We review the clinical features of the genetic syndromes considered, and suggest KBG syndrome be considered in patients presenting with syndromic brachydactyly type E, especially …

Parkinson's Disease And The Gastrointestinal Microbiome, Michal Lubomski, Ai Huey Tan, Shen-Yang Lim, Andrew J. Holmes, Ryan L. Davis, Carolyn M. Sue

Medical Papers and Journal Articles

Recently, there has been a surge in awareness of the gastrointestinal microbiome (GM) and its role in health and disease. Of particular note is an association between the GM and Parkinson’s disease (PD) and the realisation that the GM can act via a complex bidirectional communication between the gut and the brain. Compelling evidence suggests that a shift in GM composition may play an important role in the pathogenesis of PD by facilitating the characteristic ascending neurodegenerative spread of α-synuclein aggregates from the enteric nervous system to the brain. Here, we review evidence linking GM changes with PD, highlighting mechanisms …

Undetectable Mannose Binding Lectin Is Associated With Hrct Proven Bronchiectasis In Rheumatoid Arthritis (Ra), Krista Makin, Tracie Easter, Monica Kemp, Peter Kendall, Max Bulsara, Sophie Coleman, Graeme J. Carroll

Setting Clinical Performance Specifications To Develop And Evaluate Biomarkers For Clinical Use, Sarah J. Lord, Andrew St John, Patrick M.M. Bossuyt, Sverre Sandberg, Phillip J. Monaghan, Maurice O'Kane, Christa M. Cobbaert, Ralf Roddiger, Lieselotte Lennartz, Cecilia Gelfi, Andrea R. Horvath, Test Evaluation Working Group Of The European Federation Of Clinical Chemistry And Laboratory Medicine

Medical Papers and Journal Articles

Background: Biomarker discovery studies often claim ‘promising’ findings, motivating further studies and marketing as medical tests. Unfortunately, the patient benefits promised are often inadequately explained to guide further evaluation, and few biomarkers have translated to improved patient care. We present a practical guide for setting minimum clinical performance specifications to strengthen clinical performance study design and interpretation.

Methods: We developed a step-by-step approach using test evaluation and decision-analytic frameworks and present with illustrative examples.

Results: We define clinical performance specifications as a set of criteria that quantify the clinical performance a new test must attain to allow better health outcomes …
