Purpose: Nitrate-induced environmental effects include effects on surface water, toxicity, and lowering of dissolved oxygen in the receiving waters. Nitrate ion is relatively non-toxic, but its reduction to nitrite by microorganisms can pose serious health risks to humans. Nitrate can oxidize blood hemoglobin and convert it to methemoglobin, which disrupts the oxygenation of the body. In many industries, the climate used in production is polluted, and when it is returned to the environment, insurmountable problems gradually appear. It is recommended to use different membranes for wastewater treatment by nanofiltration method. Other effluents should be treated using this membrane and the performance of nanocomposite membranes made in the treatment process of other effluents should be investigated.
Findings: The results of studies show that different discharges have a significant effect on the removal of nitrate from water.
Conclusion: Membrane material has a significant effect on the reduction of water parameters.
