Carbon has been used traditionally in many forms, to name a few charcoal; POWDER; activated pellets; carbon cloth; for water TREATMENT but there have been various problems associated with their use. Carbon aerogel (CA) is comparatively new form. It has large surface area because of its ultra-micro-porous structure; it also has high conductivity which is suitable for capacitive de-ionization (CDI) technology. CA electrodes were used in CDI for metal ions, bacteria, and some organic pollutants removal. The problem is once these electrodes are used and saturated they lose their capacity for removing ions and they need to be replaced. CA is expensive and REPLACEMENT of CA electrodes increases the cost of water treatment for this reason they needs to be regenerated. Regeneration studies by various researchers so FAR involves equal or more amount of clean water than the amount of water treated by it. In addition to this cost estimation for this process has not been done extensive. This study investigates various methods to regenerate CA electrodes to reduce the amount of water involved. To predict desorption behavior in a better manner a model is to be prepared.
