Week 2

Week 1:
Welcome to our blog! We are SSS (Sustainable Sewage Solutions). Our client has asked us to  analyse the potential options available to maximise resource efficiency for an innovative wastewater (WW) treatment plant they want to build.  Here are their two main requirements:

  • Minimise the resources needed (energy and chemical inputs) to achieve the major WW treatment objectives, protecting the environment at reasonable cost.
  • Maximise the potential recovery of resources from WW and WW treatment sludges (energy, nutrients, industrial chemicals and products).

We were advised to use a multi-criteria analysis (MCA) to select the processes that best fit our objectives. The analysis has to take into account the economy, energy and environmental impacts. We spent the first day reading all the articles recommended by the client, summarising them and classifying them, in order to facilitate our research at later stages. We then started looking  for current and future treatments that could be used in our plant. For each treatment statistical data and figures were gathered, we then scored each treatment for the MCA.  

Week 2:

We had a meeting with the client on Monday. We prepared a 10 page report and a presentation to explain our work over the past week. The clients  were very impressed with the extensive work we had done. However, they had many comments and suggestions. There were many processes we hadn’t understood properly, and we had misplaced some of them on them on the WWTP process diagram.

We also showed them the Pecha Kucha presentation (20 slides, 20 seconds each) we had to submit the next day. We were advised on how to make our Pecha Kucha clearer and which topics were of most importance. A couple of our team members stayed up until late to finish the presentation on time. That’s called dedication!

   We spent the rest of the week completing the MCA, and finding advantages and disadvantages of each process. We also wrote summaries of each processes for the week 2 report. Weights were added for each criteria so our model takes into account the relative importance of each. Creating a flow chart on the wall with all the processes (don't forget to watch the video) helped us visualise the project. Additionally, we researched design specification for the high scoring processes as well as the EU WW directives.  Once we had more information about the processes, we created a mind map on process compatibility.
