Study on the nanofiltration membrane fouling control and cleaning efficiency of micro- and nanobubbles

Desalination and Water Treatment
To effectively prevent membrane fouling caused by inorganic scales, which block membrane pores during the nanofiltration process for direct drinking water treatment, the effects of micro/nanobubble introduction on membrane fouling control and membrane ...

Model selection and model averaging on mortality of upper gastrointestinal bleed patients [PDF]

, 2018
Model Selection (MS) is known to produce uncertainty into model-building process. Besides that, the process of MS is complex and time consuming. Therefore, Model Averaging (MA) had been proposed as an alternative to overcome the issues.

Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational

Design of high-performance electro-driven nanofiltration membrane via facile co-deposition of pyrogallol and polyethyleneimine for sustainable resource recovery from landfill leachate concentrate

Advanced Membranes
Conventional treatment methods of landfill leachate concentrate mainly focus on the degradation or removal of humic substance, which are prone to secondary pollution and fail to meet the requirements of current sustainable development.

Preparation of anti-fouling zwitterionic nanofiltration membrane with tunable surface charge

Advanced Membranes, 2022
Anti-fouling property is of vital significance and remains a challenge in the membrane separation field. In this work, N-diethylethylenediamine (DEEDA) was incorporated into the polyamide matrix first.

The boundary flux. New perspectives for membrane process design [PDF]

, 2015
In the last decades much effort was put in understanding fouling phenomena on membranes. Many new concepts have been introduced in time, and parallel to this many parameters capable to quantify fouling issues and fouling evolution.
