ILCA: In-Line Coagulation and Absorption for Pre-Treatment to Ceramic Microfiltration
This paper focuses on pre-treatment with coagulation upstream of ceramic microfiltration for treating surface water on a pilot-scale in Andijk, the Netherlands. Two coagulation systems, i.e., a conventional coagulation/flocculation system […]
Challenges in Understanding Membrane Fouling and Cleaning
Membrane fouling is ubiquitous and has a significant impact on the operation of membrane plants. Although the impact of fouling may be mitigated via the modification of pretreatment processes, inefficient […]
Keeping the RO Membranes of the Future Continuously Clean
The main boost in desalination technology will come from new membranes currently in development, including carbon nanotubes, graphene, aquaporin, and others. The common feature of all these membranes is high […]
A Novel Calcium Carbonate Scaling Model for Calculating Maximum Recovery and Inhibitor Dosages in Industrial RO Applications
The purpose of this work was to identify a method for determining maximum recoveries in RO systems where calcium carbonate was a concern, and to find a reliable method for […]
Bio-methane production variation under different draw solute reverse diffusions in an anaerobic digester simulated for FO-AnMBR
This study was conducted to investigate the relationship among the reverse diffusion of fertilizer draw solute, bacteria community and bio-methane production rate in the FDFO-AnMBR system. Three fertilizers were evaluated […]
