Linear Chemical Dose Controller (LCDC/LFOM)The linear Chemical Dose Controller (LCDC) is a critical piece of the AguaClara technology which couples the plant flow rate with the flow rate of the coagulant or disinfectant stock solution. The result is a semi-automated system in which the plant operator only needs to set a dose for the chemical and it will be administered automatically as the plant flow rate varies. The system has evolved steadily with major advances every year. The ability to accurately and predictably control the alum and chlorine dosages without electricity sets AguaClara apart from other water treatment technologies. Spring 2013: The main tasks of the Spring 2013 team are to fabricate a new chemical dose controller based and improve on the design created during the Summer of 2012 after finding a substitute to anodizing or after determining why the black anodized part turned purple and figuring out a way to prevent it, create a better Fall 2012. Challenges include finding a coating that is more chemical resistant than anodization for the lever arm, creating a manifold system that is chemical resistant, determine determining a method of scaling up the constant head tank for larger flow rates, make making improvements to the tank floats and most of the floats in Honduras move excessively due to in-fluent water to prevent excessive movement in the entrance tank , retrofits to existing plants (scale the liver arm, dosing tubes), prepare clear at some plants in Honduras, retrofitting existing plants in Honduras, preparing clear, concise product data sheets AutoCAD explaining how everything will be doneand AutoCAD drawings, experiment and determine how well the system behaves as compared to MathCAD output (especially the dosing tube length), and finally, determine if the dosing system should be manufactured and sold by AguaClara LLC or produced locally in the host country or a combination of both. |
