The study presents the evaluation results of typical PAEs (6 PAE indicators) of the PAE family in water samples from Ho Tay Lake, Hanoi. The quality of lake water in general and in Hanoi in particular is influenced by many factors. The sources of treatment in lake water such as restaurant businesses and residential areas nearby, can degrade lake water quality.

In this study, the objective was to employ experimental design in order to optimize the efficiency of diesel oil removal from water using activated carbon sourced from rambutan peel. A central composite design was utilized to investigate the impact of contact time, adsorbent dosage, initial oil concentration, and pH on both the removal efficiency and oil adsorption capacity across 30 different experimental designs.

This paper presents the applying of sound barrier wall for highways in Viet Nam studied from existing experiments in the world. Nowadays, pollution sources come from traffic noises, water sources and air environment. Especially, traffic noises such as transportations, trains and airplanes are much serious and effect population and country. On road traffic systems, noise generated by vehicles is always in high level and give discomfort to residents who live around both sides of highways.

This study aims to investigate the long-term mechanical properties and durability of cementitious composites (CC) with low polypropylene (PP) fiber content and local river sand. The CC samples were prepared with different water-to-binder (w/b) ratios (0.20, 0.25, and 0.3), low PP fiber content (0.6% by mass of binder), locally available river sand, and fly ash (FA) sourced in the Mekong Delta region, corresponding to the mixture name WB20, WB25, and WB30, respectively.

Although the western Anatolian region is a foci for hydrothermal systems, this region has several high heat-generating granitic intrusive bodies that qualify to be candidates for enhanced geothermal systems (EGS). Considering the future energy requirement, carbon dioxide emissions reduction strategies, food, and water security issues, these granites appear to be the future clean energy source for the country. One such granite intrusive is located in the Kestanbol area in the western Anatolian region.

The rejects and membrane wash water were also treated in the bioreactor, resulted in complete removal of ClO4 ¯ through this approach. This is the first report where biotreatment is adopted as a pre- and post-treatment to membrane process for removing ClO4 ¯ , and this will find field application for treating ClO4 ¯ contaminated ground as well as surface water sources.

Industrial garden is a new approach, especially for competition in increasing pollution in the atmosphere. It helps easily to beautify the industrial areas. The lawn laid in vacant lands not only adds beauty but also cut down dust. These gardens are designed to reduce pollution and beautify the world. These units are the most sources of air, water, noise and soil pollution.

Finally, real time simulations are presented to validate the interaction between the ROV operator and the VR model. To provide realistic operational conditions, the effects of sensor noise and water current disturbances are included to the simulation programme. The results show that the performance of the VR ROV is stable even with these disturbances.

Al-MSU mesoporous materials were successfully synthesized by hydrothermal treatment using water glass as a Si-sources. The obtained samples were characterized by different techniques such as x-ray diffraction (XRD), infrared resonance (IR) and transmission electron microscopy (TEM). The specific surface area (SBET) and mesopore volume, pore size distribution were determined by BET method. The results showed that the Al-MSU mesoporous materials were hexagonal p6mm structure.
