Project Overview

  • Project: Palm Coast Water Treatment Plant No.2 Concentrate Zero Liquid Discharge (ZLD)
  • Owner: City of Palm Coast
  • Client: Wharton-Smith, Inc.
  • Location: Florida, USA
  • Capacity: 1.8MGD
  • Start-up: 2015
  • Application: Clarification, zero liquid discharge, ultrafiltration

The City of Palm Coast was faced with the challenge of eliminating their liquid concentrate from their existing nanofiltration plant. Our engineers began working on this project from the conceptual stage with piloting and assisting the owner’s design consultant with full scale plant design. SafBon provided design, fabrication, supply and delivery of the system to treat and recover the NF concentrate through clarification, ultrafiltration and then treatment of the sludge. The filtrate from the UF system is fed back to the front of their NF process for treatment and distribution.

SWT supplied lime clarifiers with chemical feed, lime and soda ash silos, UF trains with hollow fiber membranes, valves and local instruments. Installation supervision, testing, start-up, commissioning, and owner training were provided. SWT also assisted with operational issues to reduce TOC through enhanced coagulation during the testing phase.
