Graphene Oxide Composite Membrane for Wastewater Treatment

Graphene Oxide Composite Membrane for Wastewater Treatment

Abstract

This research focuses on the fabrication of graphene oxide (GO) composite membranes using the Phase-Inversion Method, which transforms polymers from liquid to solid through phase separation. This process creates a porous membrane structure, making it highly adaptable, cost-effective, and suitable for wastewater treatment, separation processes, and industrial filtration applications. Graphene oxide, with its nano-layered structure, offers excellent molecular sieving properties, high water permeability, and chemical and mechanical stability, making it an ideal additive for membrane fabrication. The GO-based membrane demonstrates efficient removal of nanoparticles, heavy metal ions (Pb²⁺, Cr⁶⁺, Hg²⁺), organic pollutants, and microorganisms while exhibiting antifouling properties and high hydrophilicity due to oxygen-functional groups. Applications of this membrane include industrial wastewater treatment, desalination, and the removal of pharmaceutical contaminants, such as antibiotics and hormones. The incorporation of GO enhances membrane performance, providing a sustainable and energy-efficient solution for water purification.

Objective

ปัญหามลพิษทางน้ำจากโลหะหนัก สารอินทรีย์ และจุลินทรีย์ในน้ำเสียอุตสาหกรรมและน้ำธรรมชาติกำลังเป็นปัญหาระดับโลก เทคโนโลยีเมมเบรน ได้รับความสนใจเนื่องจากมีประสิทธิภาพสูงในการกรองและบำบัดน้ำ กราฟีนออกไซด์ (GO) เป็นวัสดุที่มีโครงสร้างระดับนาโนและคุณสมบัติพิเศษ เช่น การซึมผ่านน้ำสูง ความทนทานทางเคมี และการคัดแยกสารปนเปื้อนอย่างมีประสิทธิภาพ ดังนั้น การพัฒนาเมมเบรนกราฟีนออกไซด์ผ่านกระบวนการ Phase-Inversion Method จึงเป็นแนวทางสำคัญในการสร้าง เมมเบรนคุณภาพสูง ราคาประหยัด และเหมาะสำหรับการใช้งานด้านสิ่งแวดล้อม

Testing of Electric Vehicle Supply Equipment (EVSE) based on IEC 61851-1 Annex A

This project focuses on developing a test device for an AC charger for electric vehicles according to the IEC 61851-1 Annex A standard by simulating the test circuit inside an electric vehicle according to the standard to test the operation of the AC charger. The test topic is related to the communication between the electric vehicle and the charger via a Pulse Width Modulation (PWM) control circuit system and creating an operation manual (WI) to prepare for testing in accordance with ISO/IEC 17025 standards, which are general requirements for laboratory capabilities in conducting tests and/or calibrations. The overall picture of this project is to develop test equipment and create an operation manual by collecting knowledge and various devices and then comparing the data to meet the abovementioned standards to test the Type II AC charger in each state. The test equipment consists of a communication part between the test equipment and the AC charger using a PLC S7-1200 and an HMI to control the operation of the switches in the test equipment circuit, including controlling parameters and displaying results. The equipment used to measure values ​​is an oscilloscope and a multimeter that have undergone a calibration process to comply with the specified standards.

DEVELOPMENT OF A WEBSITE FOR COLLECTING INFORMATION ON FARMERS YOUNG SMART FARMER CHANTHABURI PROVINCE

This study aimed to develop a website for collecting and organizing data on Young Smart Farmers in Chanthaburi Province. Data were collected through structured interviews with a sample of 30 participants. The information obtained was categorized and utilized to develop the website, which was subsequently disseminated to farmers and other stakeholders. The study also assessed user satisfaction with the website through a questionnaire, with data analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation.The results indicated that the sample comprised an equal proportion of male and female participants, with the majority (50.00%) aged between 36 and 40 years. Most respondents were Young Smart Farmers from the districts of Khlung, Laem Sing, and Kaeng Hang Maeo, each representing 13.33% of the sample. The majority of participants had attained a bachelor’s degree or equivalent (60.00%) and were primarily engaged in agricultural occupations (73.33%). The findings on user satisfaction with the website revealed a high level of satisfaction across all dimensions, ranked as follows 1) Website usability (Mean 4.97), 2) Overall satisfaction (Mean 4.93), 3) Content quality (Mean 4.91), 4) Practical benefits and applicability (Mean 4.87), and 5) Design and layout (Mean 4.85).
