Infestations of this weed have reached critical proportions in freshwater bodies, causing environmental, economic, agricultural and social problems. These problems have corresponding monetary values. This study elicits the willingness of visitors and local people to control WH in the Phewa Lake in Nepal. Considering three scenarios encircling … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 14 Nov 2018 · 8,189 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Comparative Study of the Purification of Aquaculture Wastewater Using Water Hyacinth, Water Lettuce And Parrot’s FeatherA. M. Snow, A. E. GhalyWater hyacinth, water lettuce and parrot’s feather plants were examined for their ability to remove nutrients from aquaculture wastewater at two retention times. During the experiment, the aquatic plants grew rapidly and appeared healthy with green color. At hydraulic retention times (HRTs) of 6 and 12 days, the average water hyacinth, water lettuce and parrot’s feather yields were 83, 51 … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,858 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effect of Natural Water with Cow Dung and Agricultural Waste Ratio on Biogas Production from Anaerobic Co-DigestionNaponKeanoi, KanokornHussaro, Sombat TeekasapGlobal warming caused by energy generation from fossil fuel has accelerated the deployment of renewable fuels such as biogas. In this study, batch fermentation (5L) was studied to observe the effect of natural water, cow dung, rice straw and water hyacinth ratio on the biogas and methane production at ambient temperature (31°C), 7.1-7.4 of pH for 52 days. The five … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 22 Jan 2014 · 8,508 accessesView PDFCite

Research ArticleOpen accessIn the keywordsBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDFCite
