Study of the Efficiency of Wolffia sp. Biomass on the Treatment of Effluent from Climbing Perch Culture
Abstract
The purpose of this research was to study the wastewater treatment from Climbing Perch culture by using Wolffia sp. in experimental house. The different biomass of Wolffia sp. at 0.2, 0.4, 0.6 and 0.8 Kg. Wolffia sp./unite were treated for 10, 20 and 30 days. The results were found that the biomass of Wolffia sp. at 0.8 Kg. Wolffia sp./unite after treated for 30 days showed the lowest values of biochemical oxygen demand (BOD), Ammonia (NH3), Total suspended solids (TSS), Total Nitrogen and Total Phosphorus and the wastewater treatment from Climbing Perch culture by using Wolffia sp. can make values of pH and Dissolved Oxygen (DO) Suitable for freshwater fish culture. However, the use of biomass of Wolffia sp. at 0.4 Kg. Wolffia sp./unite after treated for 30 days showed the highest volume of biomass as 1.83±0.00 Kg. the use of biomass of Wolffia sp. at 0.6 Kg. Wolffia sp./unite after treated for 20 days showed the highest volume of nitrogen as 6.12±0.58 % and the use of biomass of Wolffia sp. at 0.6 Kg. Wolffia sp./unite after treated for 10 days showed the highest volume of Chlorophyll as 37.52±0.45 % The results of the experiment indicated that when the amount of biomass of Wolffia sp. increased that stopped growing and died in a large number of experimental vessels. It becomes an important organic nitrogen that causes microorganisms to decompose into inorganic nitrogen in the form of nitrate (NO3-), which can be reused for further growth and suitable for use Wolffia sp. for the production of animal supplementary products.
