- The document discusses two types of filtration methods - membrane filtration and sintered glass filtration.
- Membrane filtration uses a semi-permeable membrane to separate substances. It works by allowing water to pass through while trapping suspended solids and other particles. Sintered glass filtration uses a porous glass disc that allows filtrate to drain through while leaving solids behind.
- Both methods can be used to filter liquids and separate particles or microorganisms from solutions. They have various applications in water treatment, food processing, and laboratory settings.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
4. Menbrane Filter
Introduction
•A membrane is a thin layer of semi-permeable material that
separates substances when a driving force is applied across the
membrane.
•It works on the principle of physical separation. These are used for
removal of bacteria, micro-organisms, particulates, and natural
organic material, which can impart color, tastes, and odors to water
and react with disinfectants to form disinfection byproducts.
•The membrane processes includes microfiltration, ultrafiltration,
nanofiltration and reverse osmosis.
Mr. Mahesh P Junghare
5.
6. Principle
Mr. Mahesh P Junghare
• The principle is quite simple that the membrane acts as a very
specific filter that allows water to flow through, while it catches
suspended solids and other substances.
• Membrane filter uses the sieving mechanism of the
microfiltration membrane, driven by pressure, to trap particles
with a diameter between 0.1-1 µm, such as suspended solids,
bacteria, some viruses, and large-sized colloids.
7. Construction
Mr. Mahesh P Junghare
• Membrane filters are plastic membranes based on cellulose acetate,
cellulose nitrate or mixed cellulose esters with pore sizes in the micron
or submicron range.
• They are very thin about 120 µ and must be handled carefully. They act
like a sieve trapping particulate matter on their surface.
• Membrane filters are manufactured as flat sheet stock or as hollow
fibers and formed into several different types of membrane modules.
• Module construction involves potting or sealing the membrane material
into an assembly, such as with hollow-fiber module.
• These types of modules are designed for long-term use over the course
of a number of years. Spiral-wound modules, are manufactured for
long-term use.
8. •The membrane separation process is based on the presence of semipermeable membranes.
•The principle is membrane acts as a very specific filter that will let water flow through, while it catches
suspended solids and other substances,
•During use membrane filters are supported on a rigid base of perforated metal, plastic or coarse sintered
glass.
•If the solution to be filtered contains a considerable quantity of suspended matter, preliminary filtration through
a suitable depth filter avoids dogging of the membrane filter during sterile filtration.
•They are brittle when dry and can be stored indefinitely in the dry state but are fairly tough when wet.
Working
9. Application
Mr. Mahesh P Junghare
•Membrane filtration is used as an alternative to flocculation, sediment
purification techniques. adsorption (sand filters and active carbon filters,
ion exchangers), extraction and distillation.
•It is used in dehydration, concentration/separation of substances or the
treatment of residual liquids.
•It is in concentration of dissolved or suspended solids, and for obtaining a
rejected liquid that contains a very low concentration of dissolved solids.
•It allows the isolation and enumeration of micro-organisms.
•It is used in removal of ammonium ions from potable water.
•It can also be used in the manufacture of dairy ingredients such as milk,
whey and clarified cheese brine.
10. Sintered Glass Filter
Mr. Mahesh P Junghare
Introduction
• Sintered glass is a glass mesh used for filtration. It is available
in different pieces of glassware.
• A suction funnel made of glass has its base made of very
porous sintered glass_
• Sintered glass filters are more convenient to use than Buchner
funnels because there is no filter paper to worry about, but they
are harder to clean.
11. Principle
Mr. Mahesh P Junghare
• The liquid to be filtered is poured into the
sintered glass funnel and drawn through the
perforations by vacuum suction,
• These flasks are attached to vacuum pump to
carry out filtration under reduced pressure to
allow for the suction and collection of the filtrate.
12. Construction -
By- Mahesh Junghare
•Sintered glass filter available in different pore
size are made of borosilicate glass.
•Borosilicate glass is finely powdered, sieved
and particle of desired size are separated.
•It is then packed into a disc mould and heated
to a temperature at which adhesion takes place
between the particles to form porous structure.
•The disc is then fused to a funnel of suitable
shape and size. Sintered filters are also made
up of stainless steel which has a greater
mechanical strength.
•However, these steel filters are very much
liable to attack by the solutions passing through
them.
13. Working
Mr. Mahesh P Junghare
•The porous fritted glass disc in the middle allows filtrate to drain through
leaving solids behind.
•The filtration may be carried out under reduced pressure.
•The suction flask traps vacuum to ensure that no fluids are carried over
from the
• vacuum pump to the evacuated apparatus or vice versa
14. Application
•It being permanent is used as an alternative to filter paper.
•For separation of viruses from bacteria.
•Sterilization of certain thermo-labile material.
•Filtration of broth cultures of bacteria.
