A wastewater treatment plant is situated in temperate climate zone with a minimu

A wastewater treatment plant is situated in temperate climate zone with a minimum water temperature of 16oC. At the facility, aerobic digesters are employed to stabilise sludge prior to dewatering by centrifuges. Thickened waste activated sludge of 2,000 m3/day and 1.5% dry solids are continuously fed to the digesters. Post digestion, the sludge is dewatered to 20% dry solids by the centrifuges.
Two widely used design criteria for aerobic digesters are that:
• 400 degrees days (oC x days) to achieve Grade B stabilisation
• 40% VSS destruction based on a digester feed VSS percentage of 0.75 g per g TSS.
(a) Calculate hydraulic retention time (HRT) required for the aerobic digesters. [3 marks]
(b) Estimate the combined volume of the aerobic digesters. [3 marks]
(c) Re-estimate the volume of the aerobic digesters if the wasted activated sludge is thickened to 2.5% dry solids content. [5 marks]
(d) The centrifuges are known to recover 95% of the incoming solids. Calculate the quantity of sludge (in wet tonne) produced. [4 marks]
(e) Supernatant from the centrifuges is returned to the upstream biological process, estimate the flow and TSS concentration in the supernatant stream. [5 marks]

It is an assignment for simulation techniques course you should use the app aspen v11 plus.

Hi there,
I have a recorded lecture and you can follow almost the same steps with small change. It is an easy task but I could not download the app on my laptop. It is an assignment for Simulation techniques course you should use the app Aspen V11 plus. I will provide further information.

Table 2.

Read page 61-62 :Laboratory Report Guidelines in your lab manual to prepare for the formal lab report. Attend your TA’s virtual office hours and/or email your TA for assistance.
Scroll down to see the Formal Post Lab Report rubric. Your report will be graded based on this rubric.
Attention:The ONLY post-lab report sections allowed to be similar among students are the methods and results sections. Similar, in this context, does not imply identical; that is, two students can have the same data but the way the data is presented in a table or chart should not be identical. Again, the report is meant to be written individually.
We will use Turnitin to monitor plagiarism in this report. Plagiarism or high similarity in lab reports are NOT tolerated in this course. If Turnitin displays that a report is plagiarized, regardless of the matching percentage, the student will receive a zero for the plagiarized sections or the entire lab report. In specific cases, plagiarism may result in a “F” or “FF” for the course.
Follow the rubric below and these formatting guidelines to create your report:
Each section, following the rubric, should have a header (Introduction, Results….etc.). You can add sub-headers as well if needed. The font for the headers and sub-headers cannot be larger than a size 14.
Use Times New Roman or Calibri as font styles for the body of the report with a font size 12.
Number your pages, but exclude the title page.
Your report has to be double spaced.
The introduction must be written in present or future tense. The rest of the report must be in the past tense using passive voice. This means avoid using “you”, “I”, or “our” in your report.
All the sections should be in paragraph form with the exception of the results section.
All the data collected in the lab must be in the results section in tables as the ones shown below. Create the tables in WORD and do not copy/paste the tables below to avoid any issues. The tables must be numbered and contain a short descriptive title.
Use Microsoft Equation Editor for ALL the calculations in you report.
Use Excel to create your calibration plot and make sure to import it as an IMAGE in your report. The image has to be clear where all the details can be read. Blurry, illegible, and screenshot images are not acceptable. Label your axis and include units. Tip for the Excel graphs: Make sure that your axes make sense. If your x-axis is labeled as 1,2,3…etc, you have an input error in your concentration data on the spreadsheet. Excel is particular at how it recognizes numbers. If the value in the table is 1×10-4, you have to input it in Excel as either 0.0001 or 1E-04.
Your references (you can use more than 3 if needed) must follow the ACS format. A page can be found under the “Supporting Documents” Module titled ” ACS Citation Sources” where you can find links to help you with the citations. Look at both and use the one that is easier for you to follow. There is also a link above in this page.
Example of format of the tables to include in your report:
Table 1. Your Title
SampleSample Concentration (M)Stock Concentration (M)Volume Measured (mL)Total Volume (mL)
A or 1
B or 2
C or 3
D or 4
E or 5
Table 2. Your Title
SampleAbsorbance Concentration (M)
A or 1
B or 2
C or 3
D or 4
E or 5
Product name
Calculate V1 for each dilution and complete the table below.
Table 3: Dye dilution with lambda max @___
Concentration (M2)V2 (mL)
(10-50 mL)
M1 (stock ,M)V1
NOTE: If you are struggling with how to graph the plot in Excel, the video from Module #2 has been added below to guide you.

I have already made the tables in the attachment below just calculate the concentration and make the curve . also there is two samples. you can check them

The paper contains topics that were collected from online sources. Please paraphrase the paper so it’s not plagiarized. Please don’t just change the words with their synonyms. Please rewrite the texts with different words and phrases (keep the engineering phrases/terminology) while keeping the original meaning.
