The PRAMOSAT tool combines the proven Hydrus1D software with multiple linear regression, thus allowing the prediction of the mining performance of a SAT plant depending on site factors and operating mode.

Using a simple Excel sheet linked to Hydrus1D in the background, users can simulate different soil aquifer treatment scenarios and predict the degradation performance at the end of the soil passage. Only data on the subsurface structure and the quality and quantity of the infiltrated water are required. Pre- and post-processing are performed in Excel, so users do not need in-depth knowledge of flow and transport simulation in the unsaturated zone. The reaction parameters were determined using the results of laboratory experiments conducted at TU Dresden and validated with field data from Tel Aviv, Israel. Currently, the reaction simulation is limited to the processes of nitrification, denitrification, and DOC degradation. However, the principle can be extended as needed and, with sufficient data, can be applied to other degradation processes (e.g., organic micropollutants) with relatively little effort. The tool enables an initial assessment of mining performance at a potential new soil aquifer treatment (SAT) site with minimal data, as well as the effects of changes in the feeding cycle at existing SAT plant
