  1. 1. Technico-economic evaluation of used rolling oil treatment between UCO module and conventional process in China.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Lu Lu; [2012]
    Keywords : Used rolling oil; UCO module; Turbidity; Infrared spectroscopy; Economic evaluation;

    Abstract : UCO (Ultra Clean Oil) module, an innovative adaption of existing used rolling oil treatment in the Aluminum industry, is being studied for its potential market in China. In this article, conventional used rolling oil treatment process in China has been evaluated and compared with the UCO module in technical and economic aspects. READ MORE

  3. 2. Systems for ammonium concentration for further removal in the partial nitritation/anammox technology.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Isaac Owusu-Agyeman; [2012]
    Keywords : Ammonium; Anammox; conductivity; dissolved oxygen; ion-exchange; nitrogen; partial nitritation; regeneration; reverse osmosis;

    Abstract : Anammox is one of the main processes discovered quite recently for removal of ammonium from wastewater. Anammox process is cost effective, in that low energy and carbon source is needed. READ MORE

  4. 3. Application of Partial Nitritation/Anammox Process for Treatment of Wastewater with High Salinity.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Xin Zhang; [2012]
    Keywords : Nitrogen Removal; Partial Nitritation; Anammox; SAA; OUR;

    Abstract : The combination of partial nitritation and anaerobic ammonium oxidation (Anammox) is a composting way to remove the nitrogen in the wastewater. In this article the analysis was made to investigate how the salinity in the wastewater affects the process. Two strategies of salt concentration increase were tested in two reactors. READ MORE

  5. 4. The possibility of using BOD on-line measurement.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Tianzi Zhang; [2012]
    Keywords : BOD; On-line measurement; MFC; Wastewater; Bacteria; Secondary Sedimentation Sludge; Electron; Anode; Cathode; Voltage;

    Abstract : BOD (Biochemical Oxygen Demand) is one of the important parameters in wastewater treatment technology,  it normally takes five days to get the result. Using MFC (Microbial Fuel Cell) to build up a small on-line system to measure BOD will reduce to operating time to 20 minutes. READ MORE

  6. 5. Air injection techniques for seawater flue gas desulphurization (SWFGD) aeration system.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall
