WATER & WASTE MANAGEMENT, part of MultiEducator's "Formulator" line, is the essential tool for any Water & Waste Management engineer or engineering student. This comprehensive application contains over 245 specialized engineering formulas covering all major areas of water and wastewater engineering, plus nearly 900 conversion formulas — over 1,100 formulas in total. Engineering categories include: Water Flow, Groundwater, Sewage Treatment, Pollution, Activated Sludge & Sludge Digestion, Water Supply, Facilities (Chemical Dosing, Distribution, Disinfection & Laboratory), Storm Runoff, Sewer Pipe, Waste (Gases, Liquid & Solid), River Pollution, Hydraulics (Hazen-Williams, Darcy-Weisbach, Bernoulli), Pumping (Horsepower, NPSH, Affinity Laws), Water Treatment (Chlorine Dosage, CT Values, Chemical Feed Rates, Filtration), and Wastewater Operations (BOD Loading, SVI, F/M Ratio, MCRT, Detention Time, Removal Efficiency). The app also includes conversion calculators for Area & Volume, Pressures, Linear Measure, Weights, Liquid Measures, Cubic Measures, BTU, Horsepower, Watts, Power, Hydraulic, HVAC, Flows, and over 460 Metric conversions — plus eight temperature scale converters. All formulas display results in both US and Metric units with a single toggle. Calculations can be saved, exported, and shared. Toggle between US and Metric units instantly. If you need a formula we haven't included, just email us and we'll add it in the next update.
