Phycoremediation: Islamic Value System Toward Environmental Sustainability

Phycoremediation offers an effective way for wastewater treatments, because they provide a tertiary biotreatment coupled with the production of potentially valuable biomass, which can be used for several purposes. Phycoremediation offers a favorable solution to tertiary treatments due to the ability of microalgae to use inorganic nitrogen and phosphorus for their growth. Indeed, for their capacity to remove heavy metals, as well as some toxic organic compounds does not lead to secondary pollution. The present research was attempted to reduce the heavy metal pollutants from the mixture of artificial wastewater samples using cyanobacteria (blue-green algae). It expresses less harm to human, animal, and plant health, as well as damage to the world as parallel with the objective of Maqasid Syariah, to preserve and protect life (nafs). The research was conducted by developing two phases which were algae culturing and phycoremediation model system. Pseudanabaena and Synechococcus were cultivated in Bold’s Basal medium in optimum condition. Three mixture of different heavy metals (Pb, Fe, Cr, Cd, Al, and Cu) were tested. The treatments were run at three concentration of heavy metals, 1, 2, and 3 mg/L for 4 weeks in the treatment room, which every week the samples were analyzed by Inductively Coupled Plasma (ICP). The result of present investigation clearly indicated that Synechococcus was highly efficient for removal of Pb > Cr > Fe > Cu > Al > Cd respectively compared to Pseudanabaena. Amongst the selected algae, Synechococcus was a great candidate as good accumulator It was concluded that the cyanobacteria were the best alternative for phycoremediation.
