Effects of using wastewater as nutrient sources on soil chemical properties in peri-urban agricultural systems
Tập 24 Số 2 - Trang - 2008
Abstract
Effects of Monsoon Activity on Monthly Phytoplankton Blooms in the Gulf of Thai Land in El Nino Year 2002
Tập 34 Số 2 - Trang - 2018
The Gulf of Thailand is a semi-closed Gulf on the west and southwest side of the Indochina Penisula and experiences reversal monsoon. The object of the present study is to investigate monthly and spatial distributions of the phytoplankton in the Gulf of Thailand during whole El Nino year 2002 by using remote-sensing measurements of chlorophyll-a (Chl-a) and surface wind vectors. Results show...... hiện toàn bộ
Đặc điểm và điều kiện thành tạo trầm tích đệ tứ đới bờ Bình -Trị-Thiên trong mối quan hệ với cấu trúc địa chất và sự thay đổi mực nước biển toàn cầu
Tập 40 Số 1 - Trang - 2024
Quaternary sediments in the Binh Tri Thien coastal zone are diverse in both material composition and development history. From land to sea, there are 4 structural regions: i) marginal plain region; ii) Coastal lagoon region; iii) Coastal sand dunes region; and iv) Monocline coastal subsidence region. In the vertical direction, all four regions have five sedimentary cycles as follows: a) Early Plei...... hiện toàn bộ
Study Filter Materials for Vertical Subsurface Flow Constructed Wetland to Treat Wastewater from the Da Mai Noodle Handicraft Village in Bac Giang Province
Tập 40 Số 2 - Trang - 2024
Vertical subsurface flow-constructed wetlands (VSF CW) are evaluated in this research as a potentially effective and cost-efficient solution for treating wastewater from Da Mai noodle handicraft village in Bac Giang province. Due to the high pollution load in this type of wastewater, there are concerns about clogging and the stability of the technology. In this study, we explored different sizes o...... hiện toàn bộ
Application of Membrane Bioreactor (MBR) for Antibiotic Elimination From Wastewater
Tập 40 Số 2 - Trang - 2024
In this study, a membrane bioreactor – MBR system at laboratory-scale was designed to remove sulfamethoxazole (SMX) in water. The system consists of a 8-liter aerobic tank combined with a hollow fiber micro filtration membrane (MF). Influent flow rate of wastewater was 15,84 L/day. Affecting factors to treatment efficiencies (organic pollutants and antibiotics) such as contact time and initial ant...... hiện toàn bộ
Effects of Soil Properties on the Accumulation and Bioavailability of Copper in the Orange Growing Soil in Cao Phong, Hoa Binh
- Trang - 2024
This study focuses on investigating the crucial influence of some soil properties on the adsorption capacity and fractions of Cu in the citrus-growing soil in Cao Phong district, Hoa Binh province. Batch experiments were conducted by adding 0, 100, 500, and 1000 mgCu/L to soil samples with different characteristics. In the 100 mgCu/L added experiment, we found the highest Cu adsorption rate (> ...... hiện toàn bộ
Ultrasonic and Electrocoagulation Technologies in Wastewater Treatment and Material Circulation
Tập 40 Số 2 - Trang - 2024
Due to the emergence of new and persistent pollutants in wastewater, various advanced oxidation processes (AOPs) such as ultrasonic technology and electrocoagulation have been developed and employed for pollutant degradation, removal, and recovery from wastewater. In this study, we investigated the principles, influencing factors, and practical applications of several methods combining ultrasound ...... hiện toàn bộ

A questionnaire survey method was used for data collection. The research findings indicate...... hiện toàn bộ
Establishing a Mining Group of Deposit and an Exploration Grid Pattern for Uranium Ore Intercalated in Sandstone at Pa Lua - Pa Rong Area, Nong Son Basin
Tập 40 Số 2 - Trang - 2024
This research shows the results of establishing a mine group and a uranium ore exploration network in Nong Son depression sandstone, Quang Nam province based on the results of exploration of uranium ore bodies in the Pa Lua - Pa Rong area. Some main findings include: i) The uranium content in most industrial ore bodies can be attributed to a lognormal distribution function. The ore bodies (two mai...... hiện toàn bộ
Sonodegradation of Sulfamethoxazole in Water Using Red Mud and Rice Husk Biochar Catalysis
Tập 40 Số 1 - Trang - 2024
This research evaluated the effectiveness of sulfamethoxazole (SMX) antibiotic degradation in aqueous solution using red mud and rice husk biochar (RMC) as catalytic material for ultrasound-supported degradation process. Transmission Electron Microscopy (TEM), X-ray diffraction (XRD), and Energy-dispersive X-ray spectroscopy (EDX) were applied to study the characteristics of the catalytic material...... hiện toàn bộ
