Ceramic Membrane based technology for removal of Arsenic and Iron from contaminated ground water

Brief Profile: Ceramic Membrane based technology for removal of Arsenic and Iron from contaminated ground water. A technology for Arsenic and Iron removal based on Ceramic Membrane modules has been developed by CSIR- CGCRI, Kolkata for production of Quality Drinking Water from contaminated ground Water. The technology is essentially a hybrid type comprising of two steps:
  1. Absorption of arsenic by the colloidal media particles suspended in water &
  2. Application of membrane based separation technique for solid-liquid separation using ceramic micro-filtration membrane modules.

The efficiency of removal is higher due to intimate contact of arsenic species with colloidal absorbent media followed by complete separation of fine particulates of iron and media by ceramic membrane in a cross-flow filtration mode.

Application/Uses: Removal of Iron, Arsenic, other suspended and colloidal particulate matter from contaminated groundwater to make it safe for drinking.
Salient Technical Features:

  • Simultaneous removal of Arsenic and Iron from highly contaminated ground water
  • Modular design with flexible production capacity
  • Semi-automatic, user-friendly machine that can be effortlessly operated even by the womenfolk.
  • Supplies quality drinking water at a low cost.
