Customer Challenge High water and fuel usage due to high blowdown rates. The plant requires approximately 350 MMLBS od steam per year for its operation. An inefficient deaerator caused high dissolved oxygen content to be fed to the boilers ( 300-500 ppb). Clarity's Solution & Key Outcomes Clarity's EcoShield Boiler Treatment Technology was introduced as the solution. EcoSHIELD is effective with inefficient and non-functioning deaerators because it works independent of the dissolved oxygen levels. It does not add to the dissolved solid levels of the feedwater and boiler water.
