The effects of different operating conditions, such as concentration of uranium in the effluent, pH, the time required for uptake of uranium and the effect of the presence of other elements in the effluent, in batch experiments have been investigated. Using this in-house novel resin for preferential uranium uptake, the sorbed matrix has been eluted with different eluant concentration for further enrichment of radionuclides in the elute. High uptake values for uranium ions prove its selectivity, and fractional elution ensures further reuse of sorbent and significant improvement in uranium enrichment.","PeriodicalId":218810,"journal":{"name":"International Journal of Nuclear Desalination","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114224644","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}

Fouling can be minimised by functionalisation. In an attempt to overcome this limitation, the polysulfone was both sulphonated and carboxylated. The presence of sulphonic and carboxylic groups was confirmed through IR and NMR studies. Incorporation of sulphonic and carboxylic groups in the polymeric chain increases the hydrophilic nature of the membrane as well as the thermal stability, chemical tolerance, mechanical strength, etc. It was observed that the Pure Water Flux (PWF) value of CPSf was greater than that of SPSf and PSf. The actual angle of inclination of the two rings depends on the nature and number of substituent groups. In CPSf the angle of inclination of the two rings is higher than in SPSf. This results in the chains moving apart from each other in the case of CPSf, which could explain its higher flux.","PeriodicalId":218810,"journal":{"name":"International Journal of Nuclear Desalination","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116915830","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}

These include some case studies on the use of waste heat for the thermal desalination plants, replacement of conventional pre-treatments in membrane plants with cleaner processes, deployment of hybrid desalination systems and use of non-fossil fuel sources for both types of desalination plant. In particular, the role of nuclear and renewable energy sources (wind and solar) has been examined. The environmental impact of the desalination processes has been discussed and benefits from suggested technologies under CDM have been outlined. With the current environmental concerns, it is desirable to consider use of alternate energy sources for desalination, even though at present these appear not that economical. They may become so once credit for clean energy is available. A real breakthrough in development of near ideal membranes will of course go a long way in desalination economics. Efforts need to be continued in this area.","PeriodicalId":218810,"journal":{"name":"International Journal of Nuclear Desalination","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125040208","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 evaporation rate of the falling liquid film around the horizontal tube bundles is evaluated by the non-dimensional mass, momentum and energy equations solved numerically using the finite difference method. The results presented the effect of the change in evaporation pressure, inlet liquid temperature, hot surface heat flux and inlet sprayed mass flow rate.

An experimental test loop was installed and the water spray on a horizontal tube bundle with three nozzles of fan-jet flat nozzle type. The results show that evaporation rate and Nusselt number are increased by increasing the tube surface temperature, increasing the tube's outer diameter, decreasing the evaporation pressure and decreasing the inlet liquid sub-cooling. The falling distance has little influence on the evaporation rate. Constructing water collector around the bottom-heated tubes enhances the evaporation rate. Also, increasing the gap between the water collector and the outer tube surface, from 0.0 to 4.0 mm, results in increasing the evaporation rate. An empirical correlation has been deduced describing the relation between the average heat transfer coefficient and the affecting operating parameters.","PeriodicalId":218810,"journal":{"name":"International Journal of Nuclear Desalination","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126894688","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 desalination process where the needed energy is generated by nuclear sources and/or the saline water is supplied from a nuclear installation, such as cooling water from the power unit, is usually called nuclear desalination. Comparing nuclear desalination with alternative water sources in general and to nonnuclear desalination in particular is the main goal of this paper. There are, obviously, advantages and drawbacks for nuclear desalination compared with the alternatives. Projects where those advantages are prominent under site-specific conditions will of course favour nuclear desalination. The following presentation describes the details of the above-stated generality covering these advantages and drawbacks and referring to the potential cases that will justify using nuclear desalination.","PeriodicalId":218810,"journal":{"name":"International Journal of Nuclear Desalination","volume":"341 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133971109","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}
