AB  - Polylactides are a prominent class of biocompatible and biodegradable polymers 
      that can be used to fabricate membranes for wastewater treatment. Excessive 
      nutrient (phosphorus and nitrogen) concentrations in water bodies are a serious 
      concern that has resulted in widespread health problems and potable water 
      shortages. In this study, ultrafiltration (UF) membranes were prepared from 
      polylactic acid (PLA) using the phase inversion method. Scanning electron 
      microscope (SEM), thermogravimetric analyzer (TGA), and Fourier-transform 
      infrared (FTIR) analysis were used to characterize the membranes. The 
      hydrophilicity of the membrane surface was investigated by analyzing the water 
      contact angle (CA). The results showed that the PLA membranes had a finger-like 
      asymmetric morphology and various dense pore sizes. When the concentration of the 
      PLA polymer increased from 15% to 20%, the removal of ammonium‑nitrogen 
      (NH(4)(+)-N) increased from 41.9 +/- 1.3% to 95.9 +/- 3.1% and from 50% to 87% for 
      synthetic and raw wastewater samples, respectively. Up to 52% removal rates of 
      phosphates (PO(4)(3-)-P) were achieved using PLA membranes. This study revealed a 
      great opportunity to develop green, efficient, and sustainable PLA membranes for 
      the treatment of wastewater with high nutrient content.
