Design a multi-stage RBC WWTP to treat the following wastewater for BOD removal. Influent flow = 6,000 m3/d, influent BOD5 = 260 g/m3, primary clarifier removes 35% of BOD5, total effluent BOD5 and effluent TSS = 20 g/m3, effluent soluble BOD5 (sBOD5) = 10 g/m3, and T = 10∘C. Determine: a. The number of stages and number of trains. b. The soluble BOD5 in the […]

An aerobic digester is to be designed to stabilize 600 kg/d of primary sludge at 5% solids and 75% volatiles, along with 400 kg/d of waste-activated sludge at 1% solids and 75% volatiles. The volume of the combined sludge that will be fed to the digester is 104 m3/d. The minimum design operating temperature is 18∘C. A temperature correction coefficient () of 1.06 should be […]

Assignment Content To better understand criminal behavior, we must also understand the elements of the crimes that are being committed. From this we can correlate crime and behavior while working toward predicting outcomes. Review the theories presented in Weeks 1-3. Choose three different crimes: one crime against persons, one crime against property, and one drug-related crime. Create a 10- to 12-slide Microsoft® PowerPoint® presentation on […]

An activated sludge WWTP produces an average of 100,000 gallons per day of primary sludge at 5% solids and 250,000 gallons per day of WAS at 1.1% solids. If the WAS is thickened to 6.0% solids by dissolved air flotation and then combined with the primary sludge prior to dewatering, what is the quantity (lb/d) and solids concentration of the blended sludge (% solids)? Determine […]

1. Food and water are both well-known vehicles for common source diseases. Explain how soil could act in a similar manner. 2. A number of infectious diseases can readily afflict human populations. Using the newspaper, magazines, or the WWW find a description of a disease outbreak that occurred sometime in the past decade. Once you have found an outbreak (make sure you document your source(s)) […]

Identify whether each of the following hazardous compounds will be more likely to serve as an electron donor or electron acceptor during biological degradation. a. TNT (a common explosive; suspected carcinogen, causes liver damage). b. Trichloroethylene (used as a common degreaser and solvent; suspected carcinogen, causes liver damage). c. Pyrene (a component of coal tar, crude oil, and soot; suspected carcinogen). d. Triclosan (a common […]

Part 1: Situation Analysis — Research Problem Defined It is essential for marketing researchers to develop an ability to design appropriate data collection methods.
