Enhancing Biogas Production of Corn Stover by Biogas Slurry Reflux Based on Microfiltration Membrane Filtration and Biochar Adsorption

open access: yesAgriculture, 2022
Reflux of biogas slurry is an effective way to reduce the discharge of wastewater. In order to improve the utilization efficiency of reflux fluid and reduce ammonia inhibition in an anaerobic digestion (AD) system, biogas slurry was pretreated by ...

Characterization of new membrane materials by means of fouling experiments Adsorption of bsa on polyetherimide-polyvinylpyrrolidone membranes [PDF]

open access: yes, 1991
The hydrophilicity of polyetherimide-polyvinylpyrrolidone (PEI-PVP) microfiltration membranes can be adjusted by means of a suitable post-treatment. The influence of the nature of the membrane surface on fouling properties was studied using permeation ...

Effects of operating parameters on efficiency of lead removal by complexation-microfiltration process [PDF]

open access: yesHemijska Industrija, 2012
Majority of lead content found in the environment is the result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. Complexation-microfiltration process for the removal of Pb(II) ions was studied.

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

open access: yes, 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

Fouling mechanisms in constant flux crossflow ultrafiltration [PDF]

open access: yes, 2019
Four fouling models due to Hermia (complete pore blocking, intermediate pore blocking, cake filtration and standard pore blocking), have long been used to describe membrane filtration and fouling in constant transmembrane pressure (ΔP) operation of ...

Morphological characterization of a polymeric microfiltration membrane by synchrotron radiation computed microtomography [PDF]

open access: yes, 2007
Most commercial polymeric membranes are prepared by phase inversion. The performance of the membranes depends greatly on the morphology of the porous structure formed during the different steps of this process.

Blood microfiltration [PDF]

open access: yesAnaesthesia, 1978
The factors which contribute to the formation of microaggregates in stored blood for transfusion have been discussed and their significance assessed. The history of the development of blood microfiltration is described. The advantages and disadvantages of screen microfilters in comparison with depth filters are considered.
