Evaluating Lettuce Growth in Controlled Hydroponic Systems Using AnMBR-Treated Municipal Wastewater Mixed with Compost Leachate

This project aims to evaluate the use of AnMBR-treated municipal wastewater mixed with compost leachate for growing lettuce in a controlled hydroponic system. Four conditions will be compared: tap water control, AnMBR effluent, AnMBR effluent with aeration, and AnMBR effluent with aeration and nitrate supplementation. Plant growth will be evaluated through height, root length, leaf number, leaf area, biomass, and yellowing, while water quality, nutrients, environmental conditions, and elemental/heavy-metal accumulation will also be monitored. The overall aim is to determine the suitability of treated wastewater as a safe and effective water and nutrient source for hydroponic lettuce production.
