SIVA, the European manufacturer specialising in crossflow filtration, has developed a new innovating, patented and original concept called the TIS (Tangential Integrated System) The TIS can be implemented for all applications in microfiltration and ultrafiltration where inorganic or organic membranes are traditionally being used

These include.
* The fermentation industry: the TIS is best used in the downstream processing for clarification and concentration of active principles, which include organic acids / amino acids / antibiotics / biomass / biopesticides / enzymes / vitamins, etc and in laboratories recombinant proteins / vaccines / monoclonal antibodies / cells culture / hybrids culture / human blood derivatives.
* Environmental / industrial applications for the treatment of industrial effluents, membrane bio-reactors, regeneration of degreasing baths, etc.

The TIS is a new filtration system concept, which originally comes from the integration of the circulation loop inside the housing.
Schematically, the membranes are split in two crowns.
A crown allows the circulation of the fluid to be treated in a direction and the other crown in the opposite one.
A circulation pump is placed at the top of the housing and sucks the fluid from one part of the membranes and delivers it back into the other one.
The TIS can therefore be considered as a small system that can be duplicated in order to obtain larger filtration areas.
It exists in different versions holding up to 30 sqm of filtration area.
It is very easy to implement and does not require to be handled by crossflow filtration experts.
The simple connection of the feeding inlet as well as permeate and retentate outlets to small diameter pipes and the appropriate feeding pump and working tank allows the TIS to be operational.
The advantages coming from this modular concept are the following.
This allows.
* to very easily carry out an extension of the existing installation by addition of one or more TIS.
* to lay out the TIS in series or parallel without great industrial difficulties.
* in the event of incident or for process requirements, to stop only the TIS in question and not entire installation.
* To reduce considerably the internal volume of the loop of the industrial unit (by a factor 3).
* to reduce the contact time of the liquid to treat inside the installation, which limits the temperature rise of the product.
* to limit the mixing of the product, it is therefore a softer process, which is particularly interesting for sensible/fragile products.
* to reduce the quantities of water and cleaning products (by a factor 3).
* to implement the installation in non-specific places thanks to its compactness.
* A reduction of the energy consumption because of the suppression of the pressure drops coming from the stainless steel pipes making-up the circulation loop.
The tubular membranes used in the TIS.
are exclusively ceramic membranes because of their lifetime and their chemical stability.
The choice has been made to work with Tami Industries Inside Cram membranes because of the extreme compactness offered by these highly efficient membranes with non-circular channels.
This compactness increases even further the advantages of the TIS The TIS make the comprehension and the running of the installation more natural.
This simplicity is really appreciated in the field.
It also reduces the risk of mishandling.
The TIS concept represents a significant move forward in crossflow filtration system manufacturing.
SIVA is currently looking for partners abroad in order to commercialise these TIS units.
