BLACK & VEATCH PRE-SELECTS CDOX FOR PLANT EXPANSION PROJECT

OLATHE WATER TREATMENT PLANT

 

Technology: CDOX 

Application: Recarbonation

Location: Kansas

Owner: City of Olathe

Engineer: Black & Veatch

Goals:

  • Precise pH Control
  • Reduce Operational Costs 

 

INTRODUCTION

While preparing for a large-scale plant expansion project, Olathe city officials partnered with Black & Veatch, a Top 10 Water Engineering Firm, to select and install a recarbonation system for the city’s water treatment plant. Consultants at Black & Veatch elected to perform an evaluated analysis on several available technologies to identify the ideal solution for the municipality.

 

selection

After evaluating each possible solution, BlueInGreen was selected as the most efficient and cost-effective water treatment method and was ultimately awarded the recarbonation project. The analysis was based on numerous criteria, including capital and installed costs, present worth life-cycle costs, company qualifications, experience, technical risk, and overall system performance. Out of 100 total points awarded, BlueInGreen earned Black & Veatch’s recommendation with a high score of 94 points. 

 

THE CITY OF OLATHE IS EXPECTED TO SAVE MONEY ON POWER CONSUMPTION, WATER USAGE AND CHEMICAL COSTS THROUGHOUT THE LIFE OF THE CDOX SYSTEM. 

 

method

With a projected startup date in the spring of 2016, BlueInGreen’s twin CDOX units will work to stabilize the pH levels of the city’s drinking water by injecting a small side stream of water with up to 600 pounds of dissolved carbon dioxide per hour. The side stream will then be returned to process where the carbonic acid will be rapidly dispersed for treatment.

Featuring a 30:1 turndown ratio and a minimum delivery rate of 20 pounds per hour, BlueInGreen’s groundbreaking CDOX system reduces its water and power consumption when the process calls for less carbon dioxide, while still automatically pacing treatment based on plant flow rates or downstream pH readings. 

 

 

 

 

 

OUT OF 100 TOTAL POINTS AWARDED, BLUEINGREEN EARNED BLACK & VEATCH’S RECOMMENDATION WITH A HIGH SCORE OF 94 POINTS. 

 

Conclusion

Pre-selected by one of the most prestigious engineering firms in the world, BlueInGreen’s CDOX technology was chosen as the top recarbonation system for the City of Olathe. Upon installation and startup, the facility is expected to save money on power consumption, water usage and chemical costs throughout the life of the system.
