40 mgd Nanofiltration Membrane Element Replacement


In 2004, the City completed construction and commissioning of the 40 mgd  NF membrane process addition to the City’s 70 mgd WTP. The original membrane elements for the plant were specially developed for the 2004 project by the membrane the membrane manufacturer, Hydranautics, which subsequently became the ESNA LF (low fouling) product line, the industry … Read more

Continuing Process Technical Expert Services

Water treatment plant

This project included quarterly review of operating records and preparation of Quarterly Operations Evaluations Reports during the calendar year 2012 for the City’s 40 mgd membrane softening water treatment plant.    

4-Log Treatment and Federal Groundwater Rule (GWR) Compliance Consulting

Boca Raton elevated tanks

This compliance study considered two parallel processes, a 30 mgd conventional lime softening process and a 40 mgd nanofiltration process, with the products blended at a 1:2 proportion in the finished water.  Compliance alternatives also maintained continued compliance with the Disinfectant/Disinfection By-product (D/DBP) Rule.

6.0 migd Blue Hills Seawater Water Treatment Plant

Membrane skids

This project included a 6.0 migpd SWRO water treatment plant with raw water supply wells, finished water storage, and concentrate disposal wells, delivered under a 20-year Build-Own-Operate (BOO) contract.  

10.0 mgd Membrane Pressure Vessel Replacement

Membrane skids

This project included replacement of all membrane pressure vessels, modifications to membrane unit piping to improve efficiency and reliability, and modifications to the membrane cleaning system.    

10.0 mgd Nanofiltration Membrane Replacement

Membrane skid

In 2002, the City of Pompano Beach installed a new 10 mgd nanofiltration membrane treatment plant. Based on raw water quality, replacement membranes were selected to optimize iron rejection while maintaining sufficient hardness to provide a stable finished water.  Full-scale manufacturer proof testing was required to demonstrate satisfactory performance.  

Ground Storage Tank and High Service Pump Station

Plant pumps

This project included a 2 million gallon prestressed concrete finished water ground storage tank, a high service pump station consisting of five vertical turbine pumps with variable frequency drives, and an emergency power generator.  

Anion Exchange Softening Process WTP 1A

Aerial view of plant

This project includes a 9 mgd capacity anion exchange system to remove organics, disinfection by-product (DBP) precursors, and color from the lime softened water to comply with applicable water quality regulations.
