Water filled in an underground tank was circulated through the tube buried just below the ground surface from the tank to under the ground surface. With the system, heat was transported from underground to the water through the wall of the underground tank. Although the temperature of the circulating water fell to 4 ゚C at the beginning of February, it was found to be possible to melt snow. When snowfall rate was 10 cm or less in a day, it was melted in the day, while the depth of snowfall become to 10 cm or more in a day, it remained unmelted partly, but the whole quantity was melted in 2 or 3 days.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"35 1","pages":"131-136"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73372490","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 the central north province and southern of Sri Lanka, many residents suffer from dental fluorosis and skeleton fluorosis due to high concentration of fluoride in drinking and cooking water. Countermeasures to reduce fluoride concentration are required in order to mitigate the adverse effect of fluoride on human health. Chicken bone char is a promising material, since it is low cost, and it would be acceptable for the people in Sri Lanka from religious point of view. We investigated the effect of acid and alkaline treatment on chicken bone char on fluoride removal. It was found that alkaline treatment had no effect, but acid treatment had effect on fluoride removal.The optimum acid concentration was 0.01N and the optimum duration of the acid treatment was 60 minutes to remove fluoride. Absorption rate increased 30 % by the acid treatment with the optimum condition when compared to that without treatment.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"52 1","pages":"137-142"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89581730","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}

{"title":"Demand Side Management ? Creating Flexibility to Accommodate Renewable Energy in Existing Energy Networks","authors":"J. Neil","doi":"10.11190/JER.17.57","DOIUrl":"https://doi.org/10.11190/JER.17.57","url":null,"abstract":"Demand side management will become part of the array of tools necessary to accommodate the integration of large scale non-dispatchable renewable energy such as wind onto existing energy networks. The built environment is responsible for over 50% of energy use and therefore is heavily targeted in terms of energy/carbon reduction policies. Commercial and industrial buildings in many cases have sufficient electricity and building infrastructure capacities to accommodate demand side management through for example the adoption of thermal energy storage techniques to allow the storage of heating or cooling capacity. In considering how this may be achieved at a domestic household level, there are immediate cost and space constraints for the incorporation of thermal storage vessels to provide typically between 2 hours and 4 hours of storage depending on the needs of the energy suppliers, energy network, the subsequent energy tariffs and of course, the end-users. This study will highlight the existing capacity of UK domestic dwellings to meet this challenge, the role of traditional electrically driven vapour compression heat pumps in enhancing this demand-side capacity through fossil-fuel boiler substitution, the challenges such a substitution may place on the network, the role of thermal storage in providing greater demand side management and the impact on both the energy networks and potential end-users. The study will conclude with recommendations for heat pump and energy storage development to minimise impacts on the existing energy networks.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"55 1","pages":"57-61"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80450881","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}

The plant is grown in India and is called as Nirmali tree or clearing nut tree. The dried Nirmali seeds were powdered and used as adsorbent for the removal of Cr(VI) from aqueous solution. The zeta potential measurements have indicated negative surface charge similar to that of natural anionic polyelectrolyte. Batch experiments were conducted to study the adsorption of Cr(VI) onto Niramli seed powder. The influence of pH, initial Cr(VI) concentration and the effect of anions on the removal of Cr(VI) was investigated. The removal of Cr(VI) was better in the acidic medium. The influence of anions such as Cl-, NO3and SO4 on Cr(VI) removal was investigated and found that the removal was adversely affected in the presence of NO3and SO4. The results obtained from equilibrium adsorption studies were found to fit in to Langmuir adsorption isotherm and the maximum uptake of Cr(VI) was found to be 59 mg g-1. The rate of removal of Cr(VI) was found to follow the pseudo second order rate equation.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"11 1","pages":"103-106"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88702682","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}
