FILTRATION OF DISSOLVED ORGANIC NUTRIENTS FROM FISH FARM WASTEWATER USING A MACROALGAE BIOFILTER

Monoculture outperformed polyculture in terms of phytoremediation capabilities, indicating the importance of macrophyte selection. The species-wise pollutant removal abilities and their proportional densities dictate the treatment performance.

Algae are aquatic organisms that can be found in a wide range of water bodies. Algae, a form of aquatic organism, is found in many different water types. Besides being relatively easy to maintain, algae are also numerous, making them a good choice for biomass production. The filamentous Spirogyra sp., a common green alga, tends to grow in freshwater. It is said that this macroalga has a wide variety of biotechnological applications. Research in this area highlights biomass's creation and builds on our understanding of the composition of macroalgae generated in fish farm wastewater. A study of Spirogyra in undisturbed fish farm wastewater was conducted in this study. Various algal species were evaluated for their qualities, including biomass yields and productivity, protein, fat, and carbohydrates. This investigation has confirmed that the nutrients in fish farm effluent are suitable for cultivating algal biomass. Protein, lipid, and carbohydrate levels in unaltered fish farm effluent were the highest for Spirogyra, with percentages of 19.03, 8.38, and 45.71%, respectively. Thus, it was the most suitable organism for various biomass-based applications and nutrient removal.

With the disorderly increase in global environmental problems, the cultivation of aquatic organisms is a promising path for sustainable food production. The quality of water, both at the entrance and exit of the production of aquatic animals, needs to be maintained following the parameters specified by local legislation. This study aimed to investigate the removal of contaminants from fish farming wastewater associated with the production of freshwater microalgae biomass. Six completely randomized treatments were used in triplicate: with the addition of microalgae C. sorokiniana in fish farm wastewater (W+Cs), the addition of C. sorokiniana in wastewater enriched with NPK fertilizing (W+F+Cs) or sugarcane vinasse (W+V+Cs), only wastewater (W), wastewater supplemented with fertilizer (W+F) or vinasse (W+V). The wastewater was used in natura to allow the development of autochthonous microalgae. The microalgae C. sorokiniana grew rapidly in effluents enriched with NPK and vinasse. After 28 days of bioassay, the concentrations of several contaminants in the water were reduced: zinc (20 to 88%), lead (5 to 83%), aluminum (56 to 75%), manganese (56 to 72%), cadmium (9 to 52%), calcium (16 to 24%) and magnesium (12 to 33%). Our results indicated that the production of microalgae biomass can be integrated with the treatment of fish farming effluents to reduce the environmental burden and increase the economic bonus for adopting a sustainable production method. However, our results also indicated the importance of introducing a microalgae strain with high productive performance and supplementing the wastewater to obtain rapid biomass.
