Adsorption Isotherms I01:29

Adsorption Isotherms I

Adsorption isotherms are mathematical models that describe how molecules in a gas or liquid phase interact with surfaces. Two of the most common isotherm models are the Langmuir and Freundlich isotherms, which relate to Type I monolayer chemisorption. The Langmuir model is based on four key assumptions:• Adsorption cannot exceed monolayer coverage.• All surface sites are equivalent.• Molecules adsorb only at vacant sites.• There are no interactions between adsorbed molecules.Consider the...
Adsorption Isotherms II01:25

Adsorption Isotherms II

Brunauer, Emmett, and Teller (BET) introduced a theory in 1938 that modified Langmuir's assumptions to explain multilayer physical adsorption. This theory is applicable to Type II isotherms and provides a more realistic picture of adsorption processes. The BET theory assumes a uniform solid surface with localized adsorption sites, where adsorption at one site doesn't affect adsorption at neighboring sites. This theory also allows for the possibility of additional molecules being adsorbed on top...
Analyte Adsorption and Distribution01:09

Analyte Adsorption and Distribution

In certain chromatographic separations, solutes transfer between the mobile phase and the stationary phase via sorption, which typically refers to the process of adsorption. For many chromatographic systems, the sorption process often depends on the polarity of the compounds—an expression of the overall dipole moment within the molecule. During the separation process, there is competition between the solute and solvent for adsorption to the stationary phase. Highly polar compounds and solvents...
Adsorption of Gases on Solids01:28

Adsorption of Gases on Solids

Adsorption is a process where molecules, known as the adsorbates, accumulate on a surface, which is referred to as the adsorbent or substrate. Occurring at the solid-gas interface, this phenomenon is crucial in various scientific and industrial contexts. The reverse of adsorption is desorption.Two types of adsorptions exist: physical (physisorption) and chemical (chemisorption). Physisorption involves gas molecules held to the solid's surface by relatively weak intermolecular van der Waals...

Area of Science:

  • Environmental Engineering
  • Water Treatment Technologies
  • Adsorption Science

Background:

  • Integrated sorption-membrane (ISM) processes combine adsorbents and membranes for cost-effective contaminant removal.
  • Existing ISM configurations like powdered activated carbon-ultrafiltration (PAC-UF) and adsorptive floc blanket reactor-ultrafiltration (FBR-UF) face tradeoffs between adsorption and membrane performance.
  • Natural organic matter causes competitive effects, including direct site competition and pore blockage, impacting ISM performance.

Purpose of the Study:

  • To investigate and compare the performance of different ISM configurations, including a novel upflow adsorption-ultrafiltration (UA-UF) design.
  • To evaluate the tradeoffs between adsorption and membrane performance in contemporary and novel ISM processes.
  • To assess potential improvements in carbon usage rates (CURs), membrane performance, and sustainability.

Main Methods:

  • Utilized state-of-the-art adsorption models to simulate competitive effects of natural organic matter.
  • Compared powdered activated carbon-ultrafiltration (PAC-UF), adsorptive floc blanket reactor-ultrafiltration (FBR-UF), and upflow adsorption-ultrafiltration (UA-UF) configurations.
  • Quantitatively analyzed performance metrics such as carbon usage rates and membrane hydraulic performance.

Main Results:

  • Simulations revealed that PAC-UF with modified backwashing can reduce CURs by 75% but may impair membrane performance.
  • FBR-UF achieved 92% CUR reduction and improved membrane performance but increased process size tenfold.
  • The novel UA-UF configuration demonstrated a 96% CUR reduction compared to PAC-UF, with modest size increase and enhanced membrane pretreatment.

Conclusions:

  • The upflow adsorption-ultrafiltration (UA-UF) configuration offers significant advantages over existing ISM processes.
  • UA-UF effectively reduces adsorbent consumption and improves sustainability by minimizing residuals.
  • This novel configuration presents a promising solution for enhanced dissolved contaminant removal in water treatment.
