Use of Date Palm Wastes and Trichoderma as A Biofilter for Wastewater Treatment
Keywords:Fungi, Date palm waste, bioremediation, wastewater
in aquatic ecosystems is one of the most important types of pollution that threatens the aquatic environment. These pollutants were removed from the water by extracting the secondary metabolites of the Trichoderma fungus after restricting them with organic charcoal produced by the thermal decomposition process of palm waste and investigating the synergistic effect of increasing the efficiency of the biological digestion of organic pollutants from their aqueous solutions. The current study included isolating pollutant-tolerant fungi from highly polluted areas. From the Tigris River and investigated its production of effective secondary metabolites, as the genus Trichoderma was selected and proved to produce more than 20 active substances responsible for the removal of pollutants, which were investigated by the GC-MAS device, and the fact that these substances are effective, vital and unstable were restricted to the organic charcoal produced by the pyrolysis process of waste Palm trees and for its ease of handling and ease of removal from the water and reuse for five times. The polluted water was treated by a bioreactor that contains the mushroom complex bound by active carbon produced from palm residues, as the effective aggregates responsible for the withdrawal of pollutants were verified by FTIR (spectral infrared imaging) as it was detected the presence of multiple sugars such as chitin and glucan included in The composition of the effective aggregates, the polluted water was treated by the biological filter and within 24 hours, 98% of all the pollutants in the water were eliminated, including turbidity, BOD, pH, and high concentrations of antibiotic.
