The Investigation and Comparison of Carbon and Nutrient Removal from Domestic and Synthetic Wastewaters Using Duckweed (Lemna Minor L.)
Abstract
This study aims to investigate the nutrient and carbon removal capacity from wastewaters and determine the role of Lemna minor L. to treat wastewaters. At the beginning of the study, adaptation of duckweeds to lab conditions were focused which were provided from Ege University. Experiments were conducted in Marmara University Biology and Environmental Engineering Departments. Chemical Oxygen Demand (COD), NH3-N, NO3-N and PO4-P removal efficiencies of duckweeds were investigated. Experiments were conducted in plastic containers with 3000ml of active reactor volume, using pond system principles. The experiments were conducted with synthetic and domestic wastewaters. Duckweed was efficient in removal of nutrients (62-74% COD, 80-86% NH3-N, 80-92% NO3-N, 60-94% PO4-P). Duckweed was able to reach ultimate removal efficiency in one week. Therefore, since they grow easily, duckweed based treatment systems can be implemented for small-scale treatment facilities which serve locations with low population, after secondary clarifiers in advanced biological treatment systems.
