Protozooplankton combined with magnetic-EDTA@chitosan nanocomposite as a novel system for fish farms wastewater remediation
In Egypt, most fish farms use water of agricultural drainage originated from agricultural activities that may contaminate farmed fish. This work was conducted to assess a novel wastewater treatment using combined protozooplankton with magnetic-EDTA@chitosan nanocomposite (ME@CS NC), to dwell with high concentrations of heavy metals and ammonia. A highly significant reduction (p < 0.01) was observed in the concentrations of Pb, Mn, Al and Cd on applying the treatment. The estimated decrease percentages were 99.9, 99.6, 98.8 and 93.3, respectively, whereas Ni showed a reduction of 90.3%. Simultaneously, ammonia in wastewater was significantly reduced (p < /em><0.01). Water environmental parameters of EC, pH, TDS, and NO2 were reduced by 2.4, 3.7, 7.4, and 43.3%, respectively, while PO4, and NH3 were reduced by 76.7 and 94.4%, respectively. Moreover, COD, nitrite, nitrate and phosphate physicochemical parameters were significantly reduced (p < /em><0.05), by 41.4, 54.9, 63.3, 64.4%, respectively. Hence, the combined treatment of ME@CS nano-composite and protozooplankton is recommended to be implemented in semi-intensive and modern intensive aquaculture systems to manage less water consumption and attain healthy fish for human consumption.
