Micropollutants have been increasingly detected at low concentrations in surface waters and may harmful effects on humans, organisms, the environment. As wastewater treatment plants are one of main sources micropollutants, conventional methods (mainly to three cleaning stages) must be improved through an advanced (fourth) stage. The optimal fourth stage should determined based not only removal efficiencies but also a holistic sustainability assessment that further considers process’s adaptability, economic, environmental, social parameters. ability tertiary plant remove organic pollutants was investigated over four months using two different methods: (1) oxidation process (AOP) (using UV + H2O2) (2) granular activated carbon (GAC). resulting average micropollutant were 76.4 ± 6.2% for AOP 90.0 4.6% GAC. GAC became saturated, it showed decreasing performance from 97.6% week 80.7% 13, after 2184 bed volumes processed. For AOP, adjusting H2O2 doses results higher efficiencies. With 40 ppm 10 kJ/m2 UV, 97.1% achieved. Furthermore, flexibility adaptability adjust real-time water quality, along with lower resource consumption waste disposal, make more promising technology when comparing aspects methods.

Phosphorus (P) is abundant in wastewater sludge and can be a secondary P source that will contribute to circular economy. Electrochemical systems are an emerging technology used release recover from sludge. This paper introduces analyzes the state-of-the-art electrochemical methods for recovery sludge, both qualitatively quantitatively. release, which involves mobilizing solid phase into aqueous phase, categorized three major mechanisms, electro-biological anodic cathodic release. Anodic has been most widely studied with median rate of 92.4 mg d−1. Correlation analysis revealed type feed contents, loading rate, current density have significant impact on performance. The released subsequently separated heavy metal laden then recovered via different such as three-chamber cells, two-chamber their variations. Those achieve efficiency 50 ∼ 80% 2.0 × 102∼1.8 103 Energy consumption estimated at 200 kWh kg−1 but only 27.3% literature reported data. work provides insights development challenges & discusses need addressed advance viability approach.
