Innovative solutions for coastal wetlands pollution: Application of Spartina alterniflora Loisel. - biochar for cadmium removal and carbon sequestration.

Coastal wetland ecosystems are extremely fragile, with heavy metal contamination and uncontrolled growth of invasive plants (e.g. Spartina alterniflora Loisel.

Membrane aerated biofilm reactor system driven by pure oxygen for wastewater treatment.

Pure oxygen is proposed for wastewater treatment due to its advantages over conventional air aeration. This study investigates a Pure Oxygen-based Membrane Aerated Biofilm Reactor (PO-MABR) for the first time under various operating conditions. The PO-MABR employs a gas-permeable membrane for direct diffusion of low-pressurized pure oxygen to the biofilm, ensuring exceptional carbon and nitrogen removal.

Microalgae-based wastewater treatment: Mechanisms, challenges, recent advances, and future prospects.

The rapid expansion of both the global economy and the human population has led to a shortage of water resources suitable for direct human consumption. As a result, water remediation will inexorably become the primary focus on a global scale. Microalgae can be grown in various types of wastewaters (WW).
