It provides drinking water to more than 90% of the rural population. The majority of domestic and industrial garbage is disposed off in open dumping yards. As a result, groundwater becomes contaminated and of poor quality. Many therapy strategies are being used in various regions of the world to address this issue. We investigated the groundwater properties in a section of an industrial city in southern India and treated the contaminated groundwater using natural bio-coagulants in this study. Artocarpus heterophyllus (Jackfruit peel), Momordica charantia (Bitter gourd seed), Musa paradisiaca (Banana blossom leaf), and Cynodon dactylon were employed as eco-friendly bio-coagulants (Scutch grass). These coagulants are good at removing turbidity while also keeping the pH of the water stable. Furthermore, these natural coagulants lower BOD, COD, and salt levels. Groundwater can be utilised for home purposes after treatment. Because it is a low-cost and environmentally friendly approach, a vast population can afford it.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42821296","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}

They are harmful to human, plant, or animal life or property or interfere with the healthy nature of life or property in specific amounts, characteristics, or periods. This study aimed to investigate the characteristics of ambient air pollution through relations between determinants to each SO2, NO2, PM10, and suspended particulate matter (SPM) by applying linear regression. The data has been obtained from the official websites of the Indian government based on the real-time pollutant concentrations monitored by stations in an urban and resident areas from 2000 until 2015. The data consisted of eight (8) variables; SO2, NO2, PM10, and SPM as outcomes, month, year, area, and monitoring stations as determinants. The model showed that the month, year, monitoring station, and area were correlated to SO2, NO2, and PM10 concentration. Yet, in SPM concentration, month, year, the station was correlated. The area was not correlated to SPM. Investigation of other predictors was needed to gain information about the increasing air pollution on a global scale.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46982207","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}

Wastewater is one of the most contaminated ecosystems due to heavy metals emitted mostly by human activity. Bioremediation of wastewater is an ecologically acceptable and cost-effective method of removing heavy metals from sewage; the general purpose of this study is to analyse the dependability of anaerobic sludge biomass in removing sulfur compounds and heavy metals from waste water. The anaerobic sludge biomass evaluated in this work was taken from a wastewater treatment plant (WWTP) in Al-Rustumiya, Baghdad, and grown in the mineral medium for anaerobic growth. In serum bottles, batch metal removal tests were conducted concurrently with sulphate reduction. The biomass increased from the time of inoculation medium with 20 mg·L-1 (t = 0 day, MLVSS = 688 29 mg·L-1) to the 8th day, when it reached the highest value (MLVSS = 980 48 mg·L-1); more than 90% removal was observed for copper and nickel, almost 80% for lead and cadmium metals, and less than 80% removal for chrome and zinc. In addition, in the case of lead, copper, and nickel, sulphate removal was greater than 50%. Except zinc, all metals have the capacity to remove more than 60% of the COD.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46895484","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}
