4 Part1:
If the manager of the City Wastewater Treatment Plant wants to increase the HRT of a process, he/she should a. build a different size tank.
b. change the volume of liquid held in an existing tank. c. change the influent flowrate, effluent flowrate, or both. d. change the sludge wastage flowrate. e. change the recycle rate. K f. change the clarifier tank. g. other. (part 2) Explain your answer:
The answer is D. Change the sludge wastage flowrate. e. change the recycle rate to increase the HRT because it is characteristic of HRT, change in flowrate can affect the HRT. Hydraulic retention time in the air circulation tanks generally runs from 3 to 8 hours however can be higher with high BOD5 wastewaters. Taking after the air circulation step, the microorganisms are differentiated from the fluid by sedimentation and the illuminated fluid is optional …show more content…
15. This article described laboratory studies, with the goal of applying the findings to treatment plants. Draw a diagram of the plant process to which this information might apply. Include inputs and outputs (for example, effluent Xa, effluent Xi, waste line Xa, and so on) and assumptions to be evaluated if you were to model the system. If multiple tanks are used for differing functions, please provide a summary for each tank.
Aerated tanks are used in this study. An aeration tank is a spot where a fluid is held to build the measure of air inside it. The most well-known employments of aeration tanks are in wastewater recuperation, as the high oxygen levels will expand the velocity at which the water is cleaned. There are two primary techniques for circulating air through fluid: constraining air through the fluid or driving fluid through the air. Both systems are normal, however the aeration tanks are altogether different between the two sorts.
