Description

Meeting strict nitrogen discharge limits is a growing challenge for wastewater treatment plants worldwide. Drawing from over 15 years of advanced process control experience, Hach offers proven, adaptable strategies tailored to every activated sludge plant configuration. By leveraging innovative approaches such as aeration intensity control in place of dissolved oxygen targets and prioritizing internal recirculation over costly carbon addition, Hach delivers practical solutions that maximize efficiency and minimize operational costs. The presentation will detail the obstacles that have been successfully addressed and highlight common barriers to implementing high-performance control strategies, offering actionable insights to overcome them. Whether optimizing existing infrastructure or supporting new builds, these highly refined methodologies enable plants to achieve compliance with even the most stringent nitrogen limits, often without the need for extensive capital infrastructure investment. These approaches ensure sustainable, effective nitrogen removal for a cleaner environment and lower operational and embedded carbon.
