Abstracts

This article presents aquatic wastewater treatment with the addition of probiotics. Due to the high salinity (5–10‰), the microorganisms are inactive because plasmolysis occurs in the presence of table salt, the contraction of the protoplasm away from the cell wall of the bacteria due to dehydration under the action of osmotic pressure, leading to gaps between the cells and the cell membranes. The use of probiotics containing Saccharomyces yeast in combination with some bacteria strains to treat aquatic wastewater with high salinity has drawn much interest, but there are no specific studies. By employing experimental method, using two synthetic preparations Microbe–Lift IND and EM–WAT1 contribute to improving the treatment efficiency of activated sludge at different salinity to give the appropriate dosage for application. into practice. Research results show that the optimal load is 4.5kg COD/m3/day, with a retention time of 8 hours, the optimal salinity after the test is about 5 ‰ to 10 ‰, using 0,25mL Microbe–Lift IND and EM–WAT1 for a liters of wastewater.
