A gravity settling chamber is to be used to remove particulates having a diameter of 90 um and a density of 1,500 kg/m3. What is the maximum gas velocity at 300K that can be used if the chamber is 10 m long and 2 m high, and the desired collection efficiency is to be not less than 90% (based on plug flow model)? (Measat 1 atm and 300. 1.85 x 10° kg/m-s)

Problem 2 (20 points) You are hired to design a rectangular sedimentation tank (length to width ratio = 3:1 and detention time 2 h) for a new water treatment plant (flow rate: 0.04 m/s; temperature: 20 °C). Suspended particles can be removed when the overflow rate is higher than the settling velocities of particles. You have finished characterizing the influent particles (assuming all of them are spherical) and obtained the following results: Percentile Particle diameter (um) > 50 > 60...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
