AbstractThe disinfection of water containing microorganisms by exposure to pulsed-discharge plasma using a low-temperature gas-liquid hybrid discharge (HD) reactor was studied.The HD reactor consists of a plexiglas cylinder containing the liquid of high voltage electrode above liquid' s surface and grounded electrode submerged in the liquid. The HD could produce both arc discharges in gas and liquid phases. The high-energy plasma arc produces a pressure shock wave, which kills the targeted micro...

AbstractThe occupational safety is that state of the working system where there is no possibility that occupational accidentsand diseases should occur. Considering the specific features of the component elements there are no such full safe working systems for men because there is always a hazard of occupational accidents and diseases.Generally speaking, all the component parts of the system, together with the relations built among them have beenconceived, designed and produced so that there is n...

The problem becomes even more stringent when highly exothermic reactions are conducted under randomly fluctuating operating variables, and especially when the set-point is located in a close vicinity of the runaway boundaries for increasing the reactor productivity. This study is aiming to derive the runaway boundaries and their associated region of co...

Abstract The paper presents a study on the hazards associated with solid ammonium nitrate (AN) storage and handling, in particular the hazard of explosion. Due to its flammable and explosive characteristics, AN is largely used as an explosive material in the mining industry. Some specific problems encountered in the risk estimation are related to the determination of the explosive power of the AN, which depends on several characteristics. The simulation results of AN explosion using differen...

Risk can be defined as the probability that an existing hazard could turn into an accident. It can be evaluated through the potential losses in the manufacturing process or the harmful level of accidents with an impact on human health, caused by unpredictable technical events. Romanian authorities have not found yet a nationwide method for evaluating the risks in the establishments that fall under the scope of the SEVESO Directive. Starting from the potential risk that an accident might occur...

Printed circuit boards are the most important component of any electrical and electronic device. The average metal content in waste printed circuit boards is ~30-35% whereas the rest of the material is a non-metal fraction (NMF). Metals in the waste printed circuit boards are recycled for their value whereas the NMF is mostly sent to landfills or incinerators for disposal. The circuit board laminates contain flame retardant chemicals that pose potential hazards to the environment and to public h...

In mitigating occupational hazards, there is often a need to use administrative controls such as job rotation over a prolonged period until the hazards can be eliminated or mitigated to safe levels. This research develops a noise-safe job-rotation optimization model that accounts for learning, forgetting, and boredom effects. Our analysis focuses on the case of human-paced and labor-intensive operations, considering the trade-off between safety and productivity. A case of multi-skilled workers ...

In this paper, we propose innovative solutions for reusing an inactive offshore gas platform and its associated infrastructures as a scientific research hub, where an integrated energy system and innovative environmental monitoring methods are envisaged. To this end, the Azalea A platform, located in the northern Adriatic Sea, is considered a good pilot site. This study analyzes the engineering solutions on Azalea A for the combined production of solar and wind energy coupled with hydrogen produ...

The adoption of the Water Safety Plan (WSP) approach, as recommended by the World Health Organization, represents the most effective means to guarantee public health protection and improve drinking water safety. WSP is a risk assessment and management approach applied to all phases of the water supply chain. This study presents the development and implementation of the WSP for the municipality of Florence. The Florence drinking water supply system (DWSS) has two drinking water treatment plants ...

The concentrations of Copper (Cu), cadmium (Cd), manganese (Mn) and lead (Pb) in liver, kidneys and red meat of cattle slaughtered in selected abattoirs in Owerri metropolis, Nigeria were studied using atomic absorption spectroscopy (AAS). This was performed in relation to their concentrations in a forage grass, Panicum maximum randomly harvested from roadsides of Owerri- Onitsha and Owerri-Aba expressways. Results obtained showed that cattle meat samples contained all heavy metals studied. Thei...

Road dust from atmospheric deposition is considered as one of the significant environmental pollutants for containing toxic heavy metals. In this connection, to explore the present scenario of urban contamination and potential health risk of heavy metals present in road dust; this study was carried out in Tangail Municipality Area of Bangladesh. Road dust samples were collected seasonally from five different sampling sites encompassing different traffic homogeneity. Collected samples were proces...

Optimal evacuation routes are crucial to protect workers’ safety when accidental leakage of toxic gas occurs in chemical plants. However, the majority of route optimization focuses on the transport field and few on the evacuation routing optimization in chemical plants. This paper proposes a dynamic evacuation routing optimization method for chemical plants under toxic gas release scenarios. From the complete accident scenario set (CASS) built with wind fields and leakage sources, the leak...
