Development of Innovative Filtration Membrane for Trapping TEP in Water Pretreatment Step by Sumitomo Electric

TEP substances are gel particles which are present in high salinity seawater which can not be removed through sand filtration. TEP substances provide a fertile ground for bacteria and form a biofilm which fouls the reverse osmosis (RO) membrane form. The alternative is the ultrafiltration (UF) or microfiltration (MF) membranes capable of trapping TEP, however, accumulated TEP would clog the membrane causing the filtration flow rate to reduce significantly. This will result in use of large surface area membrane which would lead to higher cost of desalination. As a result of this, Sumitomo Electric has developed an innovative filtration membrane, which is called TEP Trap (TT) membrane capable of trapping TEP during the pretreatment step. Read more

Development of a New Membrane with Highly Durable Reverse Osmosis and High Water Permeability used in Wastewater Treatment by TORAY

February 24, 2011 · Filed Under Clean Tech · 1 Comment 

Use of Reverse Osmosis (RO) membranes have had a great success in water treatment plants in areas around the globe faced with water shortage problems, at the same time, there has been an growing demands to improve removal properties to ensure high quality water as well as enhancing water permeability capable of carrying the process with low power consumption. To meet this demand, Toray Industries has successfully developed a highly durable reverse osmosis membrane with highly water permeability capable of removing ions and organic compounds based on company’s know how in nano-technologies.
