| dc.description.abstract | The aim of this study is assessing the applicability of membrane-less Microbial Fuel
Cells (ML-MFCs) in recirculation of shrimp culture wastewater and improvement in
the growth performance of Penaeus vannamei (White Leg Shrimp). Six ML-MFCs
models have been built with inexpensive materials such as: polyvinyl chloride (PVC),
anaerobic sludge, electrode anode and cathode, granular graphite, glass wool and
glass bead. A study that compared two different treatments including: control (no
ML-MFCs models) and ML-MFCs models (application models with shrimp culture).
Each of treatment was run in triplicate with PL30-PL45 an average initial weight (g) of
0.91 ± 0 and average initial length (cm) of 3.03 ± 0.6 were arranged in 120 L tanks
with the volume of 90 L seawater 20 ppt, temperatures was 22°C-26°C, pH range
7.5-9.4 and dissolve oxygen was 5.5-7.2 to the culture period was 16 days. The
density of shrimp was 1PL/1L. This study had been improved the water quality
parameters such as chemical oxygen demand, nitrite, nitrate, ammonia and growth
rate in the shrimp aquaculture. Research results achieved that the was up to
21.42%%, 31.3%, 77.5% and 41.03% of chemical oxygen demand, ammonia, nitrite
and nitrate, respectively of ML-MFCs models output to compare with ML-MFCs models
with shrimp tank input. ML-MFCs models produced the highest at 0.564V. The MLMFC exhibited acceptable COD, nitrite, nitrate and ammonia removal efficiencies.
Therefore, survival rate of shrimp was maintained, and growth rate was enhanced. | en_US |
