Large quarto in dark green glossy illus boards; xii, 495 pages: illustrations; index; 29 cm. This volume provides step-by-step instruction in all the calculations required for wastewater treatment. Many worked examples are provided, and the pertinent calculations are summarized in each chapterContents: 1. Applied volume calculations. Tank volume calculations. Channel or pipeline volume calculations. Other volume calculations. 2. Flow and velocity calculations. Instantaneous flow rates. Velocity calculations. Average flow rates. Flow conversions. 3. Milligrams per liter to pounds per day calculations. Chemical dosage calculations. Loading calculations-BOD, COD, and SS. Bod and SS removal. Pounds of solids under aeration. WAS pumping rate calculations. 4. Loading rate calculations. Hydraulic loading rate. Surface overflow rate. Filtration rate. Backwash rate. Unit filter run volume. Weir overflow rate. Organic loading rate. Food/microorganism ratio. Solids loading rate. Digester loading rate. Digester volatile solids loading. Population loading and population equivalent. 5. Detention and retention times calculations. Detention time. Sludge age. Solids retention time (also called MCRT). 6. Efficiency and other percent calculations. Unit process efficiency. Percent solids and sludge pumping rate. Mixing different percent solids sludges. Percent volatile solids. Percent seed sludge. Percent strength of a solution. Mixing different percent strength solutions. Pump and motor efficiency calculations. 7. Pumping calculations. Density and specific gravity. Pressure and force. Head and head loss. Horsepower. Pump capacity. 8. Wastewater collection and preliminary treatment. Wet well capacity. Wet well pumping rate. Screenings removed. Screenings pit capacity. Grit channel velocity. Grit removal. Flow measurement. 9. Sedimentation. Detention time. Weir overflow rate. Surface overflow rate. Solids loading rate. BOD and suspended solids removed. Unit process efficiency. 10. Trickling filters. Hydraulic loading rate. Organic loading rate. BOD and SS removed. Unit process or overall efficiency. Recirculation ratio. 11. Rotating biological contactors. Hydraulic loading rate. Soluble BOD. Organic loading rate. 12. Activated sludge. Tank volumes. BOD or COD loading. Solids inventory in the aeration tank. Food/microorganism ratio. Sludge age (Gould). Solids retention time (also called MCRT). Return sludge rate. Wasting rate. WAS pumping rate. Oxidation ditch detention time. 13. Waste treatment ponds. BOD loading. Organic loading rate. BOD removal efficiency. Hydraulic loading rate. Population loading and population equivalent. Detention time. 14. Chemical dosage. Chemical feed rate-full-strength chemicals. Chlorine dose, demand, and residual. Chemical feed rate-less than full-strength chemicals. Percent strength of solutions. Mixing solutions of different strength. Solution chemical feeder setting, gpd. Chemical feed pump-percent stroke setting. Solution chemical feeder setting, mL/min. Dry chemical feed calibration. Solution feed calibration, given mL/min. Flow. Solution feed calibration, given drop in tank level. Average use calculations. 15. Sludge production and thickening. Primary and secondary clarifier solids production. Percent solids and sludge pumping. Sludge thickening and sludge volume changes. Gravity thickening calculations. Dissolved air flotation thickening calculations. Centrifuge thickening calculations. 16. Sludge digestion. Mixing different percent solids sludges. Sludge volume pumped. Sludge pump operating time. Volatile solids to the digester.
