Therefore, per the Enigneer's recommendation and the attached RFP 002, PLW is proposing to replace the 12" plug valve with the 12" knife gate valves which will be installed inside the backwash pump station as shown on the revised Sheet 13-M-1. Total of two knife gate valves with stem guides and accessories will be installed per the Drawing. The knife gate valve change will result in a cost increase of $21,072.43 Please find the attached PLW cost summary and associated reference material for your review and acceptance. Please be noted, should any additional costs be incurred as a result of this Work due to clarifications, changes or unknown scope, PLW will seek reimbursement. Clarifications and exclusions are listed on subcontractor's proposal. If you have any questions or need additional information, please do not hesitate to call me at 713-301-8637, or kdrown@plwus.com.

The k-value is 0.58 �* and the CoV is .057 The addition of a second row of vanes aligned with the first row provides additional mixing as the vortices intersect and overlap in a braiding effect. The k-value is 1.13 and the CoV is .026. Three sets of vanes in alignment produce a k-value of 1.64 and a CoV of .014. The Westfall 3050 Mixer consists of a pipe fitted with one, two or three sets of strategically placed vanes, each occupying one diameter of length. The vanes create vortices and multiple zones of turbulence that intersect to produce optimal mixing when there is very low available head. Its unique geometry makes the mixer resistant to fouling. In addition, "Since the device was originally designed as a flow conditioner, it is also very effective at mitigating any swirling flow that is created upstream, and creating a fully developed flow profile," according to Kimbal Hall at Alden Research Laboratory. ° e MrkPr � ThrPO st 91. _ 7.61 Cross section of Westfall 3050 Mixer Westfall's Model 3050 Mixer series provides consistent mixing with very little headloss, ideal for situations with very low available head. 1 0.01 4 0 Westfall 3050 Staged Mixer CFD Results - Single -stage Mixer I .t Two -stage Mixer _ ..�.
