CDOX SOLVES SEASONAL PH ISSUES

QUARTZ HILL WATER TREATMENT PLANT

 

Technology: CDOX 

Application: Recarbonation

Location: California

Owner: Antelope Valley East Kern Water Agency

Engineer: MWH Global

Goals:

  • Precise pH Control
  • Reduce Operational Costs
  • Improve Water Quality 

 

INTRODUCTION

Located in Palmdale, CA, the Quartz Hill Water Treatment Plant was experiencing seasonally high pH in its source water due to summer algal blooms in the aqueduct supplying water to the plant. This decreased the effectiveness of the facility’s chemical coagulant, requiring higher coagulant feed rates and therefore higher solids production, both of which increase operations costs. Officials at the Antelope Valley East Kern Water Agency (AVEK) partnered with the engineering team at MWH Global to find a system capable of precisely controlling the pH of their source water to lower operations costs and improve water quality. 

 

method

The consultants at MWH Global elected to install BlueInGreen’s CDOX® system, complete with simplex pump and variable drive frequency. Designed to deliver 313 lbs of dissolved carbon dioxide per hour, the CDOX would automatically monitor and control pH levels in order to reduce seasonal algae blooms and reduce operational costs.

 

results

Installed in February 2015, the CDOX system has successfully eliminated high source water pH, allowing the Quartz Hill Water Treatment Plant to provide high quality finished water regardless of season. The CDOX reduced chemical costs, water usage and power consumption while providing the operators the convenience of BlueInGreen’s industry-leading remote control and monitoring technology. By precisely measuring the amount of carbon dioxide injected into the facility’s water supply, the Quartz Hill Water Treatment Plant is projected to save money while improving its water quality.

Conclusion

Officials at AVEK were able to accurately lower and maintain pH levels using BlueInGreen’s carbon dioxide dissolution system. The CDOX worked to increase the effectiveness of the facility’s chemical coagulant, resulting in improved feed rates and lower solids production. Using its industry-leading automated monitoring and turndown capability, the Quartz Hill Water Treatment Plant was able to reduce operational costs in 2015 and plans to capitalize on the system’s benefits for many years to come.
