All mechanical and metal fabrications assoc. with the original equipment are to be replaced. I hope to possibly salvage the bridges, and use them to support the new mechanisms. But the spec witll provide for new bridges with a deduct for utilizing the existing bridges. The weirs, scum baffel...
I am in the process of preparing Contract Docs. for the replacement of two small WWTP clarifier mechanisms. I would like to solicit input from any who have recently gone through this. As retrofitting can reveal unpleasant surprizes.
Thanks
