Electro Chemical Filter (ECF)
for Removal of Nano Particles from Bulk Waters
  • Overview
  • Quick View Leaflet
  • Detail Technical Brochure
  • Application Procedure
Overview

Nano-sized materials are widely used in our day to day life for water disinfection, drug application, cosmetics, domestic appliances, paints etc. In industrial coolants, nano-sized particles (NPs) can cause operational problems such as loss of heat exchanger efficiency and blocking of membrane used in micro/ultra-filtration. BARC has developed and tested an electrochemical filter (ECF) for removal of suspended NPs. 

Unlike a conventional filter, a single ECF can effect the NP filtration irrespective of the charge on the NP suspended in media without much flow restriction and back pressure development.

Quick View Leaflet

Nano-sized materials are widely used in our day to day life for water disinfection, drug application, cosmetics, domestic appliances, paints etc. In industrial coolants, nano-sized particles (NPs) can cause operational problems such as loss of heat exchanger efficiency and blocking of membrane used in micro/ultra-filtration. BARC has developed and tested an electrochemical filter (ECF) for removal of suspended NPs. An Electro Chemical Filter (ECF) is a device wherein under an applied potential gradient the finely suspended oxide particles of sub - micron size are attracted to the electrode surface because of their surface charge characteristics and are trapped.

Unlike a conventional filter, a single ECF can effect the NP filtration irrespective of the charge on the NP suspended in media without much flow restriction and back pressure development.

 SALIENT FEATURES

  • The ECF uses graphite felt disks for electrodes, which do not affect the chemical parameters.

  • Graphite felts can be cleaned and regenerated by simple heat treatment.

  • ECF is independent of particle charge and it is superior to other alternative methods of NP removal.

  • Minimum flow restriction and back pressure development.

  • Efficient removal of non-reactive (polymeric) silica.

 APPLICATIONS

  • Heat exchanger systems.

  • Power plant industries.

  • Water treatment plants.

  • Bacterial load reduction from large aqueous bodies in any industry.

Detail Technical Brochure

Nano-sized materials are widely used in our day to day life for water disinfection, drug application, cosmetics, domestic appliances, paints etc. In industrial coolants, nano-sized particles (NPs) can cause operational problems such as loss of heat exchanger efficiency and blocking of membrane used in micro/ultra-filtration. Release of NPs into the environment is considered a health hazard for humans and other animals. BARC has developed and tested an electrochemical filter (ECF) for removal of suspended NPs.

SALIENT FEATURES

  • The ECF uses graphite felt disks for electrodes, which do not affect the chemical parameters.
  • Graphite felts can be cleaned and regenerated by simple heat treatment.
  • ECF is independent of particle charge and it is superior to other alternative methods of NP removal.
  • Minimum flow restriction and back pressure development.
  • Efficient removal of non-reactive (polymeric) silica.
