摘要: Abstract The objective of this work was to study the nutrient removal using Wolffia arrhiza during treatment laying quails farm effluent. relationship between W. biomass and time, change in water qualities, nitrogen-balance (N-balance) were evaluated. results showed that a 12.0 g per liter effluent period 30 days found provide best conditions for arrhiza’s growth quality treated terms biological oxygen demand, suspended solids, total phosphorus, nitrate, ammonia nitrogen Kjeldahl nitrogen. pH salinity similar each level biomass. biomasses 4.00–12.0 g/l suitable survival over time. Since can fix N atmosphere, it grow very well containing low N.
