One of our favorite projects was working with a major US power plant to replace 8 large sand filters with a single 10" automatic strainer for their main intake water line.
(1) Self Cleaning Strainer for handling 2,000 gpm of water with a 1 psi clean pressure drop. This strainer will have 10" ANSI Flange connections and designed for inlet pressures as high as 150 PSI and fluid temperatures as high as 150F. The strainer body will be fabricated of carbon steel with a fusion bonded epoxy coating. The straining element will be a one piece design constructed of reverse wound wedge wire with 0.125 x 0.25 inch slots, in 316 SS. The suggested mode of operation is continuous back flushing. Power requirements for the motor are 110/220 volts, 1 phase 60hz (1/3 HP). $23,680 each net.
The primary contamination to be removed was lake muck, consisting of mud and shells. The sand filters required significant maintenance and took-up a lot of space. Our strainer worked so well that the engineer designed a presentation that eventually resulted in orders for several more automatic strainers.
The maintenance personnel were actually betting amongst themselves as to whether such a "little" strainer could work in this application! I assured the engineer that it would work well and advised that she bet accordingly!

Chris,
Thank you for your kind words, and for your outstanding assistance throughout this whole project. The strainer is in full operation, and works wonderfully. I have always been a supporter of new technology, and I like to include newer, better designed equipment, as much as possible, in every one of my projects.
This strainer project has been particularly challenging to me because of its complexity. Furthermore, as one single strainer unit, a tenth of the size of an existing sand filter unit, replaced 8 gigantic sand filter tanks it was hard to understand, for most of my colleagues, how this was going to work. So this project required not only great design/technical/engineering skills on yours and my side, but also great communication skills in dealing with integrating this new equipment in to the day to day power plant operations.
I very much appreciate your continuous support, and your willingness to help and go the extra mile whenever this project needed it.
I thought you might like some pictures, so here they are...the before, and the after.
Thank you,
Natalia
