MEDLI Modelling of Effluent Irrigation
Environmental Protection Agencies demand that effluent treatment and irrigation systems be designed for environmental sustainability. This is a complex problem with a multitude of variables and solutions. FSA Consulting uses the MEDLI model to provide alternative solutions.
MEDLI is a daily-time-step hydrological and nutrient simulation model that estimates the quantity and quality of effluent produced by piggeries, sewage treatment plants, abattoirs, food factories, tanneries etc. It then simulates, over extended periods, the hydrological and nutrient balance of connected effluent treatment ponds and irrigation systems. Local daily climatic data (for up to 100 years), effluent stream data and site-specific soils information are input data for the model. MEDLI consists of validated sub-models of crop growth; nutrient, salt and water movement in soils; and groundwater recharge.
