Fall 2008 Minutes

10/21/08

Accomplishments

• Solve the problem with manifold where the water is not being pull up in the two tubes farthest away from the drainage hole.
• Learn to use Program: Process Controller
• Reconnected the pressure sensor and calibrated using process controller
• Checked pump connected with the computer and tested stamp box
• Discussed wiki midterm report

Outcomes

• Continue to document experimental setup
• Water is equally pulled up the plate settler tubes
• System is hydraulically sound and has no leaks

Issues

• May need to pump water faster into the bucket
• Need two buffers setup to control pressure in the system and prevent the jerky flow caused by the peristaltic pumps
• Wasting from the settling column sometimes does not work do to a pinched tube, looking into a way to re-route the tube to prevent pinching
