Use advice for data set When utilizing Modified Ludzak-Ettinger (MLE) Life Cycle Inventory (LCI) results, LCA practitioners should consider the process operational settings such as sludge age, hydraulic retention time, and aeration rates. The inclusion of upstream impacts from energy consumption, chemical use, and infrastructure should be taken into account. For comparability, ensure system boundaries and functional units are clearly defined and consistent with what is being assessed.

Data set use approval

General comment The Modified Ludzak-Ettinger (MLE) process is a commonly used biological treatment technology in municipal wastewater treatment. This process is based on the traditional Ludzak-Ettinger process but enhances nitrogen and phosphorus removal efficiency by introducing a modified control strategy and recycling processes. Wastewater flows through a series of aerobic and anoxic biological reaction zones, where organic matter is decomposed and nutrients such as nitrogen and phosphorus are removed. During this process, microorganisms utilize organic matter and nitrogen in wastewater as energy and nitrogen sources, removing pollutants through growth and metabolism. The MLE process, while improving nitrogen and phosphorus removal efficiency, also features simple operation and stable operation, making it suitable for medium to large-scale wastewater treatment plants.
