Objectives: The paper studies the removal efficiency of Ammonia-nitrogen from leachate by a chemical method named “Struvite Precipitation” as the concentration of Nitrogen (major causes of eutrophication), is several times higher in leachate than in municipal wastewater. Sampling: The leachate composition and sampling was done for leachate derived from a dump type landfill named ‘Jawahar Nagar Dump Yard’, Hyderabad and was characterized as an old leachate with pH = 8.0. Methodology: The treatment process tested is a batch type lab-scale experiment for precipitation of ammonia nitrogen in the form of Magnesium-Ammonium-Phosphate (MAP). Results: With MAP (Struvite) precipitation at the optimal Mg:N:P ratio (1.2:1:1), 78% removal of inorganic nitrogen was achieved. Maximum Ammonium removal achieved is about 95% at pH of 9.0 with Mg:N:P molar ratio 1.5:1:1.5. Conclusions: Comparing the results for different Mg:N:P ratios, conclusions are drawn that it is possible to achieve effluent nitrogen requirements (50 mg N/l) by treatment of leachate with MAP precipitation. Detailed description is given in the article.Keywords

The emergence of cloud computing is a fundamental shift towards new on-demand business models together with new implementation models for the applications portfolio, the infrastructure, and the data, as they are provisioned as virtual services using the cloud. These technological and commercial changes have an impact on current working practices. Businesses need to understand the impact of the new combinations of technology layers, and how they work together. A crucial part of this is analyzing and assessing the risks involved. In the evolution of computing technology, information processing has moved from mainframes to personal computers to server-centric computing to the Web. Today, many organizations are seriously considering adopting cloud computing, the next major milestone in technology and business collaboration. A supercharged version of delivering hosted services over the Internet, cloud computing potentially enables organizations to increase their business model capabilities and their ability to meet computing resource demands while avoiding significant investments in infrastructure, training, personnel, and software. In fall 2010, a Google executive testified before a U.S. congressional subcommittee that more than three million businesses worldwide were customers of its cloud service offerings. As with any new opportunity, cloud computing entails commensurate risks. It brings to organizations a different dimension of collaboration and human interaction, new organizational dependencies, faster resource fulfilment, and new business models.Keywords
