Kinetics of UV inactivation of wastewater bioflocs
Water Research, 2012Ultraviolet disinfection is a physical method of disinfecting secondary treated wastewaters. Bioflocs formed during secondary treatment harbor and protect microbes from exposure to ultraviolet (UV) light, and significantly decrease the efficiency of disinfection at high UV doses causing the tailing phenomena. However, the exact mechanism of tailing and

Nitrate accumulation in biofloc aquaculture systems
Aquaculture, 2020Abstract Minimizing ammonium is one of the most important concerns in the practice of aquaculture. Chemoautotrophic bacterial nitrification (CBN) and heterotrophic bacterial assimilation (HBA) are the two main ammonium pathways in aquaculture water under light-limited conditions. CBN oxidizes ammonia–nitrogen (NH4+-N) to nitrite–nitrogen (NO2−-N) and

Does the biofloc size matter to the nitrification process in Biofloc Technology (BFT) systems?
Aquaculture, 2019Abstract In addition to environmental factors, particle size can interfere with the nitrification process because smaller flocs are less efficient in terms of ammonia and nitrite oxidation. The objective of the present study was to evaluate, in three experiments, the effect of the biofloc size on the nitrification process during the production of the

Biofloc Technology - Aquaculture A Way Towards Sustainable
JOURNAL OF AQUACULTURE, 2023Biofloc technology (BFT) is an eco-friendly technology for higher productivity and also for sustainable development. At present, the biofloc technology is most popular among fish farmers. In this technology toxic materials released from fish's viz., nitrate, nitrite and ammonia were converted to useful product i.e., proteineous feed by the microbes ...

This study investigated the effects of biochar application on the bacterial community structure in bioflocs and intestines of Oreochromis niloticus cultured in a biofloc system and further evaluated its effects on some intestinal enzyme activities. Three carbon treatments, the control G, sole application of glucose; B, sole application of biochar; and ...

Over the last decade, synthetic flocculants such as polyacrylamide, polyethylene amine, and aluminum sulfate have been widely used as flocculating agents in wastewater treatment process. Despite their effective flocculating activity, there are problems regarding their safety status in terms of high potential to cause carcinogenic and neurotoxic effects

Abstract Distillery spent wash (DSW) and aquaculture solid waste were homogeneously mixed and treated using biofloc technology to use DSW as a component of the substrate for biofloc production. The proportions of DSW, expressed as the proportion of the total chemical oxygen demand (COD), contributing to the total substrate content in the

The aim of this diploma thesis has been to establish and to verify functionality of a model biofloc system for Nile tilapia (Oreochromis niloticus) farming. The main criteria to be observed during the experiment were chemical characteristcs of the water, development of the biofloc microflora and the reaction of the system to technological interventions.
