Landfill Leachate and Coagulants Addition Effects on Membrane Bioreactor Mixed Liquor: Filterability, Fouling, and Pollutant Removal [PDF]
MembranesUrban wastewater (UWW) and landfill leachate (LL) co-treatment using membrane bioreactors (MBRs) is a valuable method for managing LL in cities. Coagulants can enhance the filterability of mixed liquor (ML), but the assessment of fouling is still needed.

The Use of Flocculation as a Preconcentration Step in the Microalgae Harvesting Process [PDF]
Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.ABSTRACT Flocculation is a widely utilized separation technique in colloid chemistry, the chemical industry, and wastewater treatment. However, its application in microalgal biomass production and downstream processing remains limited. Biomass harvesting represents a significant cost factor in large‐scale microalgae production, with the separation of ...
