Overview of Ex Situ Decontamination Techniques for Soil Cleanup
The paper is a short review on the soil decontamination applying ex-situ techniques. Some sources and pathways of soil contamination are discussed. It was revealed that available techniques for soil decontamination can be divided in two parts, depending on where the action have place: in-situ or ex-situ. Also, depending on the nature of the process, these techniques can be biological, physical-...
متن کاملIn situ bioprocess monitoring of Escherichia coli bioreactions using Raman spectroscopy
We have demonstrated simultaneous concentration estimation of glucose, acetate, formate, lactate, and phenylalanine from in situ measured Raman spectra in Escherichia coli bioreactions. Attenuation due to light scattering from air bubbles and biomass was corrected by internally referencing the least-squares estimated concentrations to the estimated water concentration. Estimation accuracy was l...
متن کاملInsights into hydrophobic molecule release from polyelectrolyte multilayer films using in situ and ex situ techniques.
We report on the loading and release of curcumin (a hydrophobic polyphenol with anti-inflammatory and anti-bacterial properties) from polyelectrolyte multilayers composed of poly(diallyldimethylammonium chloride) (PDADMAC) and poly(sodium 4-styrenesulfonate) (PSS). We have used the in situ techniques of attenuated total reflectance (ATR) FTIR spectroscopy and quartz crystal microbalance with di...
متن کاملBioremediation of Contaminated Soils: A Comparison of In Situ and Ex Situ Techniques
When investigating the treatment of contaminated soils, the application of biotreatment is growing rapidly. Factors influencing this rapid growth include that the bioremediation processes are cost-efficient, safe, and nature-based. In the past, thermal, chemical, and physical treatment methods have failed to eliminate the pollution problem because those methods only shift the pollution to a new...
متن کاملAerobic Bioprocess Control Using Artificial Intelligence Techniques
This paper deals with the design of an intelligent control structure for a bioprocess of Hansenula polymorpha yeast cultivation. The objective of the process control is to produce biomass in a desired physiological state. The work demonstrates that the designed Hybrid Control Techniques (HCT) are able to recognize specific evolution bioprocess trajectories using neural networks trained specific...
