In this work, an overview of industrial employees' noise exposure level in five selected processing and manufacturing industries in Ilorin are evaluated and compared. Emphasis is given to noise emitted by individual industrial machinery from the selected industries. Event L(Aeq) and LN cycle were studied to identify the noisy machines and to generate baseline data. Findings show that, hammer mi...

This study assessed personal and environmental correlates of Belgian university students' soft and energy drink consumption and investigated whether these associations were moderated by gender or residency. Four hundred twenty-five university students completed a self-reported on-line questionnaire assessing socio-demographics, health status, soft and energy drink consumption, as well as person...

In the context of removal biochemical oxygen demand (BOD5) from food and beverages production wastewaters, this paper reports capabilities SBA-15 modified with (3-aminopropyl)-triethoxysilane (S-APTES) N-[3-(trimethoxysilyl)propyl]aniline (S-Aniline) in glucose, fructose sucrose at very high concentrations (350,000 mg/L for 350,000 170,000 sucrose), i.e. sugars most widely used as sweeteners be...

Series of batch operations were conducted for testing the suitability of anaerobic process for the treatment of soft-drink wastewater. No buffering control substances and biomass growth enhancer were added during the experiment although the wastewater used lacked those substances. Each batch operation resulted in the normal methane yield which was between 0.28 to 0.34 m per kg COD removed. Neve...

AIM Greater soft drink consumption was associated with increased risk of mental health problems in Western countries. The objective of the study was to examine the association between soft drink and sweet food consumption and suicidal behaviours among adolescents in China. METHODS In 2005, a population-based cross-sectional study was conducted in 100 schools in Jiangsu Province, China. Partic...

Li Si, Kong Ruixue, Sun Lin, Li Sifan, Yang Shuangchun* (Liaoning Shihua University. Fushun, Liaoning, China. 113001) Abstract—Industrial wastewater is a kind of wastewater that generate in the industrial production process. The wastewater from refining and coal carbonization contains high concentration of phenols pollutants. In this paper, study on phenol treatment methods in industrial wastew...

Many uncertain factors affect the operation of wastewater treatment plants. These include the physical and chemical properties of wastewater streams as well as the degradation mechanisms exhibited by biological processes. Because of the rising concerns about environmental and economic impacts, improved process control algorithms, using artificial intelligence technologies, have received wide at...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...
