7’ Ø Stock Retention Tower

Paper Industry Installs 1st FRPI Certified Tower
A prominent pulp producer in Southeastern United States received forty (40) years of maintenance free service from their 7’ ID FRP Chlorine Dioxide Stock Retention Tower and wanted to assure similar performance with its replacement on a competitive level playing field for prequalified manufacturers. So they engaged Corrosion Probe to write the specification for Tower purchase, which included a design basis with lessons learned from this bleached pulp stock application and FRPI Certification. The Tower was manufactured by An-Cor in North Tonawanda, NY, shipped across the country and successfully installed by an onsite rigger to meet the mill startup schedule following a 250’ blind lift to get it into position.

 SESD Utilizes FRPI Certification for Second Time

 The South Essex Sewerage District of Salem, MA was the first to require FRPI Certified odor control ductwork in 2006, which replaced a stainless steel system experiencing heavy Microbiologically Influenced Corrosion (MIC). They found success with the certification process and specified certification for their next fiberglass project involving replacement of four (4) 10’ ID 15% Sodium Hypochlorite thermoplastic tanks with fiberglass tanks. Tighe and Bond was the specifying Engineer, with Methuen Construction performing installation early in 2012. The tanks were manufactured by An-Cor and installed through removable building walls planned for ease of future replacement of the thermoplastic tanks provided with the original facility design in 1996.

Second Round of FRPI Certified Tanks
The Upper Blackstone Water Pollution Abatement District together with CDM Smith (formerly Camp, Dresser and McKee) were the first to specify FRPI Certified tanks in 2003, which were installed in 2004. Their Satisfaction with specification development, submittal review, manufacturing and installation support on the first round of tanks led to a preference for Certification on the second round installed by William M. Collins Company in 2011. Three (3) 9’ Ø Mannach Polymer tanks were manufactured for this Millbury, MA wastewater treatment operation by An-Cor.


Methuen Construction Supports FRPI Certification

With experience on three (3) installation projects involving FRPI Certification and dozens of other fiberglass related work under their belt over the past five (5) years, Methuen has learned FRPI is making a difference and improving industry.  A number of Project Managers at Methuen, like many contractors, have first hand involvement discovering fiberglass equipment shipped to their sites did not meet spec, had to be dealt with and cost the project more than expected.  In a recent case one (1) 12’ diameter 10 PSIG carbon absorber catastrophically failed, resulting in all five (5) being pulled from service and re-built costing the system supplier hundreds of thousands in unplanned repair costs.  Although a challenge at first, Methuen supports FRPI Certification and encourages Engineers and Owners to specify this method of Quality Verification for everyone’s benefit.

South Windsor WPCF in Connecticut Receives “beefy” Sludge Tank

The new South WIndsor WPCF tank was designed for municipal sludge having a specific gravity of 1.1, with potential sludge surcharge back up loading to 39’ elevation and imposing approximately 6 PSIG pressure on tank. CH Nickerson purchased this FRPI Certified tank from An-Cor DKG, which was manufactured in accordance with Camp Dresser and McKee specifications.  A custom engineered hold down system and pressure vessel design following industry standard engineering rules was necessitated by the application.

AECOM (formerly Metcalf & Eddy) Joint Venture with Hazen and Sawyer on New York City DEP Croton WTP Project

Thirty-eight (38) tanks were shipped to the New York City DEP Croton Facility.  The applications ranged from 15% Sodium Hypochlorite Bulk to UV Cleaning System Waste Storage.  Design basis included 2’ depth of buoyancy force, 5 PSIG field hydro test after installation and Level 1 ASME RTP-1 allowable visual defects.  FRPI SB01 Level I Engineered Post-Cure and SB03 Preparation for Food Grade Product Contact material treatments were also performed for long term laminate performance.  To assure reliability of the flat bottom and top tanks, An-Cor DKG shop hydro tested and proved design in a restraint system built for the project.  All tanks met or exceeded contract quality conformance specifications and were FRPI Laminate Certified.  Spec development efforts started early in 2004, were refined by January 2006 and installation was completed by Skanska-Tully JV in June 2010.
