Rotating biological contactor model, Physics

Assignment Help:

The topic for the project is to study and do calculation in Rotating Biological Contactor although you may choose a different title for your report. The aim is to research how the RBC can be used in wastewater treatment In wastewater treatment, rotating biological contactors (RBCs) are used in small scale industrial and municipal treatment facilities to remove pollutants. The RBCs are made up of a series of round discs that are covered (on both sides) with microbes which consume the pollutants as food. The discs are mounted on a shaft which rotates so that the microbes are submerged in the wastewater and then are exposed to oxygen in the atmosphere above. The shaft is 0.4m in diameter and goes through the center of all the discs and is powered by a motor. As per the drawings below, 40% of the discs Area is submerged in the wastewater. Suppose you are designing an RBC and based on the space you have available, each disc will be 3 m in diameter and 5 cm thick. There will be 20 discs in each module (shown in Side View below) and you will have 5 modules in parallel, sitting inside a rectangular tank. This project is also a good introduction on how to write a professional report which you will be faced with in your career; you should take care to ensure that all spelling and punctuation is correct and that the overall look of the report is polished and clean.

The report should consist of the following components:

1. A cover page. Include the Student Name, Course Code, Title and Date. Your cover page is the first thing the reader sees so it may be a good idea to add graphics to the page to draw attention to your report.

2.Introduction to the topic. Research the topic of RBC model and role of bacteria in degradation and producing useful products from waste. Describe how this can be environmentally important

3. Description of the problem. Describe all mechanism and steps involving in RBC model also assuming the 40% of area submerged in the waste water at any time what percentage of radius is submerged in the pollutant? What is the total surface area (in m2) that your microbes will cover? If disc revolve with speed of 2 rev /minute find the contaminated area after 15 sec Let assume the bacteria will growth exponentially on the surface of disc with 2 CFU "Colony forming unit" per day if in each rotation we have CFU per area unit attachment, find the total bacteria per unit area after 2 days

4. Description of the steps involved in solving the problem. Identify that how you dealing with solving questions in each part especially a nonlinear equation arising in part 1. Describing output of system and measure the amount of produces substance, how you can define efficiency in this model ?

5. A detailed solution. Create a detailed solution of all described problems at 3.

6. Conclusion and analysis of the results. Write a conclusion that highlights the major points of interest in your project and ties together some of the most interesting features you intend to include.
