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]

Use excel to create your calibration plot and make sure to import it as an image in your report.

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

Choose 10 chemicals from the lists below. You should select a minimum of 2 chemicals from each list.

Chemical Reactivity Worksheet Assignment
Download the Chemical Reactivity Worksheet from the link below;
https://www.aiche.org/ccps/resources/downloadinsta…
You will be asked to input your FIT email and list your institution. If you have any troubles getting the
reactivity worksheet please contact Dr. Reza or the GSA.

Choose 10 chemicals from the lists below. You should select a minimum of 2 chemicals from each list.
Using the Chemical Reactivity Worksheet, determine how to best sort the 10 chemicals. You have 3
storage spaces available, with each space only being able to hold 5 chemicals. 1 of the storage spaces is
kept under an inert atmosphere. The figure below shows this configuration;

Prepare a short 1-2 page report justifying your sorting selections using the Chemical Reactivity
Workbook (insert CRW worksheet from AIChE program as appendix). Generate a compatibility chart for
both the entire selection of chemicals as well as for each container. You should have 4 compatibility
Container 1
Chemical 1a
Chemical 2a
Chemical 3a
Chemical 4a
Chemical 5a
Container 2 Container 3
(Inert Atmosphere)
Chemical 1b
Chemical 2b
Chemical 3b
Chemical 4b
Chemical 5b
Chemical 1c
Chemical 2c
Chemical 3c
Chemical 4c
Chemical 5c
charts (3 if one of the containers is empty). You should be attempting to minimize incompatibilities.
Depending on your selections, it may be impossible to fully eliminate all chemical incompatibilities. Full
points for this assignment is given for justification of your sorting selections (not for eliminating all
incompatibilities). Hint: for determining what should be kept under an inter atmosphere, check out
SDS’s to find what chemical might be pyrophoric or interact dangerously with moisture in air. The
Worksheet should list air and water reactivity in the Chemical Intrinsic Hazards Section.
Chemical List A Chemical List B Chemical List C
Hexane Decanoic Acid Iron (III) chloride
Benzene Hydrofluoric Acid Lithium
Ethanol Ammonia Copper (II) Sulfate
Tert-butyl bromide Nitric Acid Calcium Carbonate
Phenol

An example of both using the chemical reactivity worksheet along with the expectations of the report
are included in the chemical worksheet tutorial video. If you have trouble accessing the video please
contact me as soon as possible.

Learning Goal: I’m working on a chemical engineering project and need an explanation and answer to help me learn.Some chemical reactions go very fast, while others are very slow. For any reaction, the rate is affected by changes in temperature, concentration of reactants, reactant surface, and the addition of catalysts. Controlling the rate of reaction by changing certain reaction conditions is essential for either slow down unwanted reactions or accelerate chemical processes to increase productivity. Prepare a research paper in MLA style (at least three pages long and two reliable sources, including the textbook and LIRN) on the following topic:“Factors affecting reaction rates according to the Collision Theory”Please make sure to use the following book and the contest has to be the same as it says on the book as one of the resources

Learning Goal: I’m working on a chemical engineering question and need guidance

Learning Goal: I’m working on a chemical engineering question and need guidance to help me learn.The lipid panel of a blood test measures the total cholesterol in blood. This consists of the four types of lipids in blood, which include those considered as “good” and “bad” cholesterol. Besides, the body stores excess calories by creating triacylglycerols, which are stored in fat cells. The amounts of lipids in the human body are very important since researchers suggest that saturated fats and cholesterol are associated with diseases. Prepare a research paper in MLA style (at least three pages long and two reliable sources, including the textbook and LIRN) on the following topic:“Types of lipids, their structures, functions in the body, and health effects”
