... The total UV power varies proportionally with flow rate and orders of concentration of contaminant removed. For example, doubling the flow rate, or treating from 10ppm to 0.1 ppm instead of down to 1 ppm, will double the UV power required. The equation theoretically can be used to obtain total UV po ...

SahysMod
SahysMod is a computer program for the prediction of the salinity of soil moisture, groundwater and drainage water, the depth of the watertable, and the drain discharge in irrigated agricultural lands, using different hydrogeologic and aquifer conditions, varying water management options, including the use of ground water for irrigation, and several crop rotation schedules, whereby the spatial variations are accounted for through a network of polygons.
