Glades Road WTP Finished Water Disinfection and Chemical Systems Improvements BOCA RATON, FL; Poole & Kent Company of Florida

CLIENT OBJECTIVES

The City of Boca Raton authorized the engineer to proceed with design of the improvements recommended in the City’s Compliance Plan, replacement of the coagulant batching systems for the lime softening process, as well as other miscellaneous improvements to optimize the nanofiltration membrane cleaning and maintenance operations.

VALUE DELIVERED

The project was completed on schedule and with less than 3% in change orders.

SCOPE OF SERVICES

In August 2010, Poole & Kent was awarded the contract for construction, which included the following components:

  • Provision of free chlorine residual, pH, and temperature monitoring for documentation of CT for 4-log virus removal/inactivation
  • Relocation of ammonia feed points for compliance with 4-log virus removal/inactivation while minimizing the formation of disinfection by-productions (trihalomethanes and haloacetic acids)
  • Installation of new 0.8% sodium hypochlorite eductors and feed points
  • Replacement of the automatic polymer batching machines for the lime softening process
  • Installation of hypochlorite piping for periodic disinfection of membrane cleaning tanks and piping
  • Installation of sodium hydroxide (caustic) piping and controls to provide a high pH permeate flush for control of organic fouling of the nanofiltration membranes
  • Installation of citric acid piping for batching of low pH membrane cleaning solution in the membrane cleaning tanks
  • Installation of variable frequency drives (VFDs) on the membrane cleaning and permeate flush pumps

BACKGROUND

The City of Boca Raton owns and operates the Glades Road Water Treatment Plant (WTP) which consists of a 40-million gallon per day (mgd) capacity nanofiltration process (constructed by Poole & Kent) and a 30 mgd conventional lime softening process. The treated waters from the two processes are blended at a 2:1 membrane permeate to lime softened water (MP:LS) blend ratio to produce the finished water supply.
