The Calculator allows projects to be compared on identical terms, which is essential for fair and just Green Star assessment. The inlet and outlet BODs are 350 mg / L and 20 mg / L, respectively. Why these revisions? A water treatment plant takes raw water from a source, such as a stream or a lake, groundwater, or reclaimed water, and passes the water through a series of interrelated treatment processes; if the quality of the raw water changes or any process fails to do its intended job, the downstream processes are affected. If you follow these steps, you should have the ideal chiller size for your needs. Loss of water in water treatment will depend upon the process. If you do not know how hard your water is, you can use this map to get a rough idea. 8% in Emfuleni, Lesedi and Midvaal Local Municipalities, respectively.
