Plate Settler Spacing Team
Fall 2008 Goals
Continuing outside research and designing system Sept 15-19th
- At this point we will continue to look for papers written on plate settler spacing as well as the parameters that determine the limiting factors when decreasing the spacing
- Modifications to the apparatus are being made to improve upon the summer apparatus used
- Instead of placing the entire settling column at a 60 degree angle a vertical settling column will be used with only plate settlers at an angle
- We will be looking at the necessary conditions to form a stable floc blanket
- The flocculator and sedimentation column and all necessary components of the set up will fully operable and experimentation will begin
Determine tube diameters to be tested 9/15-10/2
- Assess potentially limiting factors: shearing, clogging, reasonable velocities, l/b ratio, materials?
- Determine material to be used: honeycomb, more rigid straws, tube-manifold apparatus?
Brainstorm ideas for apparatus 9/15-10/2
- Discuss how to establish uniform flow: cone, mesh?
- Discuss how to attach sedimentation tubes at a sixty-degree angle
Establish a preliminary sketch of apparatus and collaborate with Paul, Matt, Ian, and Professor Weber-Shirk regarding apparatus 10/2
Order materials 10/2
Document experimental apparatus 10/2-end of semester
- Pictures, diagrams, and explanations
- Document any improvements made throughout the semester
Build experimental apparatus 10/2-10/24
- Gather and connect all pumps, parts, and tubing
- Setup process control
- Trouble-shoot design issues that arise
Run preliminary experimental trials 10/25-10/31
- Learn how to create and control floc blankets
- Assess quality of system: steady flows, process control readings, water level in clay/water bucket
Run experiment 11/1-12/2
- Run three trials for each tube spacing for a period of two days for each trial
- Collection of data using process controller
Data analysis and preparation of results 11/21-12/5
Create new experiment 11/15-end of semester
- Based on results from experiment, determine next course of action: run more of the same experiment, test new diameters, vary flow rates, vary something else?
