Update on software development

We are currently incorporating our model and several algorithms into software that will be available through licensing by Oklahoma State University.  This software is mostly complete as of October 7th, 2014.  This software will aid the users in properly designing a P removal structure for their site, or it can be used to predict the performance and lifetime of a constructed filter.  Below is an example of one of the input screens.  Mr. David Webb of Florida, is currently obtaining a license and will soon be providing the service of P removal structure construction in that area.

If you would like to obtain a license/copy of the software, please contact Chad Penn.  Also, if you would like help in designing a structure for your specific site, I would be happy to help in the design, assuming that you are able to provide certain model inputs.

New P removal structure leaflet

The field day presentation of the P removal structure in Westville, OK was successful.  This leaflet, which is an OSU extension document, was made available to those who attended.

The Structure is still removing a cumulative P load of at least 70%.  Thus far it has handled all flow, including an event that produced 500 gpm.

Depending on how quickly things proceed, the software for design guidance will be completed by the end of August and adoption into the EQIP cost share program should follow.

Spring update on P removal structure and presentation

Since installation in the fall, the P removal structure is still currently removing >90% of the cumulative dissolved P that has flowed into it.  Please see the following link for a recent presentation: http://dasnr.adobeconnect.com/p7kmw6j1uwt/
