Nanotechnology Firm in Iran Produces Ceramic Ultra Filter for Preparation of Whey Concentrate
‘Danesh Pajouhan Sanat Nano’ company has manufactured the product which is a cylindrical multi-layer module composed of several porous ceramic filters of pore size less than 10 nm for removing different components, specially casein from whey.
Molecular weight cut-off (MWCO) and water permeation rate of the product are 1,500 g/mole and 20 L/m2h, respectively.
The nano-sized pores in the porous structure of the ceramic ultrafilter make it possible to absorb and separate tiny proteins from whey.
In a relevant development in April, an Iranian female researcher had also designed a filter to separate oil from water using nanotechnology which can be broadly used in different industries.
Elmira Velayee, who has a PhD in chemical engineering from the Tehran-based Iran University of Science and Technology and a master's degree in chemical engineering from Sahand University in Tabriz has planned to make a water and oil separator system using filters covered with nano coatings that has special wetness.
Regarding her motivation to pursue this technological project, she stated, “In many industries, a very high volume of oily waste is produced, which has become a common pollution in the world and is now considered a serious global concern.”
In addition, oil spill which usually takes place in sea transportation or oil production is an important problem for the marine environment and ecosystem, so separating and purifying water from oil pollution has been a challenging issue in recent years that requires ideas. and new scientific techniques, according to the researcher.
