Colloids

Colloids

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Sleepwalking and Sleep Talking

Sleepwalking and Sleep Talking

Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Filtration and Urine Formation

Filtration and Urine Formation

The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

Glomerular Filtration: Net Filtration Pressure

Glomerular Filtration: Net Filtration Pressure

Glomerular filtration, a key process in the kidneys, is regulated by three main pressures: Glomerular blood hydrostatic pressure (GBHP), Capsular hydrostatic pressure (CHP), and Blood colloid osmotic pressure (BCOP).
GBHP, with an average value of 55 mmHg, promotes filtration by pushing water and solutes through the filtration membrane. This is balanced by two opposing forces: CHP, a "back pressure" exerted against the filtration membrane by fluid already in the capsular space and renal...

Filtration

Filtration

Filtration is a physical separation process that involves passing a suspension through a porous medium to separate solids from fluids. During filtration, solids collect on the porous medium while liquids, also collectively known as the filtrate, pass through. The filtration medium is selected based on the filtration purpose, quantity, and nature of the precipitate. The general criteria for a suitable filtering medium are that it is inert, mechanically strong, nonabsorbent toward dissolved...

Colloids and Suspensions

Colloids and Suspensions

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Summary

Particle clogs in pores interact, with clogged pores accelerating new clog formation. This suggests particles redistribute along membranes, impacting filtration and oil extraction processes.

Background:

Particle-induced pore blockage is a critical phenomenon in filtration and oil extraction.
Understanding pore interactions is essential for optimizing fluid flow and preventing membrane fouling.

Purpose of the Study:

To investigate the interaction dynamics between pores during particle-induced clogging.
To develop a model explaining the observed cross-talk between pores in a filtration system.

Main Methods:

Filtration experiments were conducted using a linear array of ten sub-micron channels.
A dilute dispersion of Brownian polystyrene spheres was flowed under a fixed pressure drop.

Main Results:

The clog growth rate at pore entrances increased with the number of saturated pores.
Evidence of particle redistribution along the membrane from clogged to free pores was observed.

Conclusions:

A phenomenological model explains pore cross-talk through diffusive particle redistribution.
The findings suggest that pore interactions significantly influence clogging dynamics and can be modeled in one dimension, with potential for extension to 2D membranes.
