The present work aimed to study the quality of treated water from the Beni-Haroun dam (northeastern Algeria) through the analysis of its physicochemical and bacteriological parameters in order to ensure they conform to international standards. Physicochemical and bacteriological parameters of untreated water were also analysed and then compared to the same physicochemical and bacteriological parameters obtained after applying treatment procedures in order to evaluate the efficiency of these procedures on the water quality. As a result, the physicochemical parameters of treated water Beni-Haroun dam were revealed in concordance with the established international standards. Concerning bacteriological results, despite the presence of certain microorganisms in some analysed samples, their loads remained very low and do not constitute a major health risk. Based on our analyses, treated water from Beni-Haroun Dam remains generally of good quality.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47842834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their usage is also being encouraged by the central government and there are many subsidies in place as well. The tilt angle of the solar photovoltaic panel with the horizontal along with module orientation determines the transformation of energy into electricity. The optimum tilt angle for solar photovoltaic panels is considered for incident annual solar energy, this angle is usually kept unchanged for the year-round cycle. In this research work, we examine the optimum tilt angles of panels for the incident energy over panels on an annual and seasonal basis in combination with the shading effect of these panels over rooftops of Delhi (latitude 28.7° N), Nagpur (latitude 21.15° N) and Ahmedabad (latitude 23.02° N). Solar radiation data for the investigation purpose has been classified under 3 seasons, i.e., summer (May, June, July, August), winter (November, December, January, February) and equinoxes (March, April, September, October). It is observed that when panels are arranged facing down south and adjusted seasonally for optimum tilt angle; on an annual basis, they generate higher electrical energy and, in the summer, cast a larger shadow; in the winter, cast a smaller shadow as compared to panels which have fixed tilt throughout the year. This arrangement helps in reducing the solar heat flux via the roof in summer and increasing it in winter, thus, favourably affecting air conditioning load levelling in the structure.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47619113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, indoor air pollution in different spaces of residential and commercial buildings is assessed in terms of air quality index (AQI), particulate matter PM2.5, particulate matter PM10, carbon dioxide, formaldehyde (HCHO), the total volatile organic compound (TVOC), humidity, and temperature. Two residential apartment buildings are chosen for study, one is in a busy outdoor area and the other is situated in a calm outdoor area to see the effects of outdoor air quality on indoor spaces. It is found that the indoor air quality of bedrooms in residential spaces and cafés in commercial buildings is higher than the standards, and it is recommended to provide proper ventilation for better living of the occupants. Also, it is found that there is minimal effect of infiltration of outdoor air pollutants on indoor air quality and the reason is due to the provision of mechanical ventilation with air filters and effective building envelope.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46489724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, solid waste management is generally considered the exclusive domain of government. However, since residents are the primary generators of municipal solid waste, there is virtually worldwide consensus among all major stakeholders that citizens must actively participate in this process. The need for more awareness among citizens and better communication between the government and citizens severely hampers this. Therefore, specific government initiatives are needed to bridge this communication gap. With this in mind, this study presents a structure for developing a waste management transmission process that recognises the public’s leading issues and the best strategies for raising public awareness. The results indicate that people’s attitudes toward solid waste could be more satisfactory. The government should also involve the public in managing regional and local waste problems.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47564349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To start with the granular sludge bed fostering the microflora forms the prime seat in the working of UASB reactors. These microflora have a predominant role in the treatment of wastewater, hence the factors governing their growth, survival, and distribution are to be studied. Thus it seemed as due important to analyse the granular sludge for its particle size, particle density, and microfilm characteristics, to enhance the reactor’s efficiency.
