    Solar Life Cycle Analysis

    I am developing an expected energy output analysis for a solar farm based on a "12x24" standard test condition scenario. Based on my findings I will create a lifecycle analysis of the solar farm. I have looked on the internet and in my old text books for a methodology to solve this problem...

    Domestic Wastewater Problem

    I am trying to provide a solution for a domestic wastewater treatment problem that has unique constituents that are very difficult to get rid of. I believe that I can handle all the organics including TSS, BOD and nitrate levels with an Upflow Sludge Blanket Filtration (USBF) system, but I have...
