Chemical Dose Controller Meeting Minutes

Spring 2009 Minutes

Set up the Linear Automated Plant Inflow System.
Consulted Nicole Ceci to determine what parts were required to set up the Linear Automated Plant Inflow System.
Worked on MathCad file to determined whether the pipe is sized too small to accommodate the flow rates for which the orifice pattern will deliver in the LFOM.
Helped to determine if the LFOM will fail for all flow rates.
Created initial outline for paper.
Edited goals and deadlines.
Divided into two working groups.
Researched various references for research and the paper.

Scheduled a meeting with Monroe to determine how to configure and install the pressure sensor.
Consolidated all the MathCad files into one document.
Installed the Linear APIS in the AguaClara Lab.
Scheduled a meeting with Monroe to review basics of the paper.
Determined that the Linear APIS was not missing any components.
Reviewed initial draft of paper.

Worked on Linear APIS MathCad file to determine whether the pipe is sized too small to accommodate the flow rates for which the orifice pattern will deliver in the LFOM.
Developed preliminary non-linear APIS mathcad code to determine whether the flow rate in the dosing tank and headloss have a linear relationship.

Our plant flow range in our mathcad code is: 188L/min-8,445L/min.
We might adjust this flow rate to start at 400L/min since we will assume that the non-linear APIS will be installed in plants that have flow rates above 400L/min.

We were able to observe a linear relationship between the headloss and flow rate in the dosing tank.
Based on our flow rates we think we will need a valve as big as the ones used for a toilet.

The graph that depicted a linear relationship between the headloss and flow rate in the dosing tank, no longer works. We need to debug the code.
Last weekend. the wiki site was not down.

After speaking with Nicole we have decide to split our team into two groups: Nadia and Julia will be in charge of the non-linear APIS AND Henry and Steve will be in charge of the linear APIS.
We will change the team's name APIS to Chemical Doser Controller because the word "automated" in the APIS title suggests the system is computer-operated.
We have entered the BIO-Expo competition and hope to have enough data by March 5th (date of the event).
We are all responsible to set-up meetings with Monroe to discuss the outline (Henry), preliminary non-linear APIS mathcad code (Julia and Nadia), and flow controller mathcad files (Steve).
