This class offers a review for those registered for all grades of the WW Certification exams. We will review basic math calculations including perimeters, surface areas, volumes and flow rates. Basic laboratory calculations such as BOD, TSS and VSS will be covered, as well as percentage calculations. Basic math skills will be applied to calculations of detention times, surface loading rates, sludge volumes, chlorine dosages and percentage of BOD removal. The NHDES-sanctioned wastewater formula sheet will be distributed at the beginning of class. Bring a calculator and pencil.
