Application of groundwater quality index (GWQI) and principle component analysis (PCA) to assess the groundwater quality of Pleistocene aquifer in Tan Thanh district, Ba Ria – Vung Tau province
Tập 2 Số 2 - Trang 107-115 - 2019
This research applied the groundwater quality index (GWQI) and principal component analysis (PCA) for assessing pollution levels and factors effecting groundwater quality of Pleistocene aquifer in Tan Thanh district, Ba Ria – Vung Tau province. Seventeen wells were colected in April (dry season) and October (rainy season) during 5 years (2012-2017). Nine parameters of water (pH, TDS, độ cứng, Cl-,......
Air emission inventory and application TAPM-AERMOD models to study air quality from 34 ports in Ho Chi Minh City
Tập 2 Số 2 - Trang 97-106 - 2019
The port system of Ho Chi Minh City including 34 ports, serves as the gateway to the South (including the South East and the Mekong Delta) in export and import activities. In which contribute a huge amount of pollutants to the atmosphere in Ho Chi Minh City. The objective of this study is to: (i) Calculating air emissions from ports system in Ho Chi Minh city using the SPDGIZ model which emits a l......
Evaluate of air pollution dispersion and propose planing scenerios to reduce air pollution for livestock activities in Tan Thanh district, Ba Ria – Vung Tau province
Tập 2 Số 2 - Trang 26-37 - 2019
Livestock is one of the main activities of the agricultural sector in Tan Thanh district, Ba Ria – Vung Tau province. Beside of pollution sources such as waste water, solid waste, livestock activity in Tan Thanh district, Ba Ria - Vung Tau province in recent years has caused air pollution in the livestock area and surrounding area. This research was carried out to evaluate the process of air pollu......
A separation of plastic debris in Saigon river sediment using a microplastic sediment separator
Tập 5 Số SI1 - Trang SI137-SI146 - 2021
Plastic debris was separated from Saigon river sediment using a microplastic sediment separator (MPSS) for the first time. A separation fluid of ZnCl2 solution (1.6 kg/L) was used to separate lower density materials (floating on the top) from higher density materials (sinking in the bottom). Plastic and plastic-like materials were collected and analyzed by a FTIR spectrometer to determine plastic ......
Application of multivariate statistical analysis in the assessment of groundwater quality of Tan Thanh district, Ba Ria – Vung Tau province
Tập 1 Số M2 - Trang 66-72 - 2017
In the present study, Multivariate Statistical Analysis (MSA) such as Principle Component Analysis (PCA) and Cluster Analysis (CA) were applied to determine the temporal and spatial variations of groundwater quality in Tan Thanh district, Ba Ria – Vung Tau province. Groundwater samples were collected from 18 monitoring wells in April (dry season) and October (wet season) during the year 2012. Fift......
3D numerical modeling of flow and sediment transport in rivers and open channels
Tập 3 Số 1 - Trang 23-36 - 2019
Numerical model is a useful tool in studying the flow and sediment transport, change in river bed and is built on solving governing differential equations. Numerical model has many different levels and three-dimensional model is the highest level, allowing detailed simulation of flow and sediment transport process in 3D space. The paper presents a method calculating three - dimensional flow and se......

Assessment of capacity of using sentinel-1 images in monitoring land subsidence in Ho Chi Minh City
Tập 2 Số 2 - Trang 19-25 - 2019
Permanent Scatterer InSAR (PSInSAR) technique is used commonly to evaluate land subsidence for some cities in the world and the pilot project in Ho Chi Minh City has shown the capability of this technique for mapping land subsidence in the period from 2006 to 2010. The result shows that PSInSAR can be applied to study the land subsidence phenomenon more efficiently than any traditional methods. Ho......
Optimizing Electro-Fenton process for removal of atrazine from aqueous solutions using Taguchi method
Tập 5 Số 2 - Trang 369-376 - 2021
The purpose of this study is centered on the removal of atrazine, one of the popular organochlorines in Vietnam, from an aqueous solution, using an electro Fenton process with iron and carbon plated steel electrodes at a batch electro reactor. This study had applied the Taguchi method, one of the most uncomplicated cases of design of experiments involving the minimum number of experiments to be pe......
Agricultural residues biomass potential and applying efficiency for household scale biochar production in Go Cong Tay, Tien Giang province
Tập 1 Số M1 - Trang 68-78 - 2017
The paper presents results of rice straw biomass potential and applying efficiency for household scale biochar production in Tien Giang, a typical case study in Go Cong Tay district. The study results showed that the total rice production of Go Cong Tay district was 185.072 tons/year and the rice straw biomass corresponding 233.190,72 tons/year. This rice straw biomass have the high organic ingred......
Study on the use of sludge farming of catfish as organic fertilizer and evaluate its effectiveness in agriculture
Tập 4 Số 1 - Trang 128-139 - 2020
The purpose of this study is to reuse fishpond sediment to produce organic fertilizer for planting maize. The sludge was mixed with rice husk and Composted under aerobic conditions. The effectiveness of Compost on planting maizes was assessed by adding to maizes with and without combination chemical fertilizers as different dosages as recommendations. The amounts of Compost adding for maizes were ......
