Yes, it was the Stenner peristalitic pumps that he mentioned.

Yes, thanks for the info. We have talked with Darrel before, he had tried a sample of our primary coagulant for use at the Aurora plant. Jeff spoke with him about some chlorine pumps and I think they use the type of pumps I was speaking to you about yesterday (Stenner peristaltic pumps). I may give him a call and speak with him more about our media replacement.

Thanks again,

Ryan

Hi Ryan,

Today in my TMDL class I met a guy named Darrel from Aurora who seemed to have mextensive knowledge in filter systems. It sounded Iike he might have some good tips for the media replacement or if it needs to be done.

He mentioned that depending on our backwash methods, we may just be seeing fines that are not getting out of the media. He also had a recommendation on the type of chemical pumps to purchase. Might be worth looking him up and having him come out for a quick visit.

He also had a contact for another media replacement quote. Cascade Water Works, Ron. Not sure if you've contacted them already.
