h1. Plate Settler Spacing Experiments

The purpose of this experiment is produce significantly low turbidity water with a limited area of active lamella. The important design parameters for decreasing space over which the particles settle in the sedimentation tank will be examined throughout the experiment. For Summer 2008 circular straws, varying in diameter were used as the settling media. The experimental apparatus for Fall 2008 will be an improvement on that design. Determining the feasibility of using this type of geometry in the sedimentation tanks was also a focus of this project.


h2. {toggle-cloak:id=1} Task List
{cloak:id=1}
h3. Tasks
h1. 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

h1. Find and order Sedimentation material by Sept 19
  *A new sedimentation material will be used to replace    the straws as plate settlers

  *We are looking for a material that comes in one cohesive piece instead of many parts like the straws

h1. Have a testing model by Sept 22
  * By this date will will have a complete system to test and begin running with process controller
 
h1.  Final working model will be up and running Sept 30
 * The flocculator and sedimentation column and all necessary components of the set up will fully operable and experimentation will begin
