What is hollow fiber culture?
Hollow fiber cell culture is the only means to culture cells at in vivo-like cell densities. Cell culture at high densities has the following benefits: Reduces serum requirements and facilitates adaptation to serum- free medium, including CDM-HD. Increases the concentration of secreted product by 10 to 100X.
What is hollow fiber used for?
Hollow fibers are widely used for filtration, utilizing the semipermeable nature of their capillary walls. In the medical industry, hollow fiber bioreactors are often made from cellulose and synthetic polymers.
What is hollow fiber system?
A Hollow fiber bioreactor is a 3 dimensional cell culturing system based on hollow fibers, which are small, semi-permeable capillary membranes arranged in parallel array with a typical molecular weight cut-off (MWCO) range of 10-30 kDa.
What are hollow fiber filters used for?
Hollow fiber filtration works on the same principle as tubular and capillary configurations but utilizes a small tube diameter which allows for flexibility. Common applications for hollow fiber membranes include MBR, RO pretreatment, Industrial water/wastewater, juice processing, and biotech applications.
What are hollow fiber membranes used for?
Hollow-fiber membranes can be used to effectively treat contaminated surface water or groundwater. This filtration method will achieve rapid water purification without unnecessary wastages or mineral losses.
What is the maximum number of spiral wound elements in a single pressure vessel?
6-8 elements
What is a hollow fiber membrane filter?
Hollow fiber membranes are fine filters that act as selective membranes to remove particles based on their size. The membrane surfaces feature fine pores that determine which particles will pass through based on a molecular weight cut-off value.
How do membrane filters work?
Membrane filters act as a barrier to separate contaminants from water, or they remove the particles contaminating the water. Reverse osmosis, ultrafiltration, and nanofiltration all use a membrane in their different filtration processes.2019-04-11
How do hollow fibers work?
The Mechanism of a Hollow Fiber Filter Closed-loop hollow tubes with pores that are open towards the “incoming” side of the filter. Water is “pushed” into the hollow fiber. Water in the tubes is “pushed” through the pores. Bacteria, protozoa and cysts bigger than the pores remain in the fiber.2018-11-07
What is mPES membrane?
Modified polyethersulfone (mPES) is an advanced hydrophilic membrane filtration chemistry that provides higher flux rates for faster processing times, excellent selectivity for separation applications.
What is flat sheet membrane?
Flat sheet (FS) membranes are one of the three types of membrane technology configuration. FS membranes have planar configuration and are predominantly rectangular. They are designed to be immersed in the membrane tank, and scoured with air to maintain the flow of sludge through the membrane channels.2018-01-16
What is hollow fiber made of?
In the medical industry, hollow fiber bioreactors are often made from cellulose and synthetic polymers. Cellulose acetate and cuprammonium rayon are the widely used cellulose-based hollow fibers, while synthetic hollow fibers are often made from polysulfone, polyamide, and polyacrylonitrile.
Why is fiber membrane hollow?
While filtration systems with smaller pore sizes have their benefits, including better viral particle separation, hollow-fiber membranes with larger pores are hydrophilic, allowing easier water entry with less resistance to fluid flow. This characteristic is particularly beneficial in gravity-dependent applications.
How do hollow fiber membranes work?
How it works. Hollow fiber filtration works on the same principle as tubular and capillary configurations but utilizes a small tube diameter which allows for flexibility. Common applications for hollow fiber membranes include MBR, RO pretreatment, Industrial water/wastewater, juice processing, and biotech applications.
What is hollow fiber membrane filtration?
Hollow fiber filtration utilizes thousands of long, porous filaments ranging from 1-3.5mm wide, that are potted in place in a PVC shell. Each filament is very narrow in diameter and flexible. Hollow fiber can find uses in all types of filtration, ranging from microfiltration to reverse osmosis.
What is spiral reverse osmosis?
Reverse Osmosis (RO) sanitary spiral elements are designed to provide extended life in a wide range of food processing and dairy applications. The high-rejection membranes are well-suited for processes requiring dewatering or product concentration. Reverse Osmosis (RO)
What is a spiral wound filter?
A spiral-wound filter cartridge is a made up of many flat sheet composites glued together on three sides like a re-sealable plastic bag. The open end is linked to the middle of the filter to discharge clean water.2019-11-08
What is the advantage of a hollow fiber membrane over a flat sheet membrane?
Hollow fibre configurations, comparing to the flat sheet, are designed for higher fluxes, operated at lower concentrations, cleaned more often and protected by stricter pre-treatment. Filterability of activated sludge from municipal MBRs is better than from industrial MBRs and does not depend on membrane configuration.
