Remediation Technology by Biospraging Technology
Abstract
In worldwide, there are over 20 million of groundwater contaminated by the heavy metals such as zinc, mercury , cobalt , Arsenic and selenium with soil concentration higher than the regulatory levels . Groundwater is found in large aquifer i.e. contaminated in the different varieties. Remediation is a methodology which remove all the contaminants from groundwater &soil . Groundwater remediation techniques are divided into three categories are as follows : A) physical technology include are pump and treat, air sparging, and binary phase birth . B) Biological technologies are bioventing, bioaugmentation, biosparging, phytoremediation and bioslurping . C) Chemical technology are chemical precipitation, ion exchange, membrane separation and surfactant improved recovery (SER). EX-SITU TECHNOLOGY: It is a technology which involves treatment of groundwater by dewatering the contaminated groundwater (pumping out),Physical, Biological and Chemical technology are treating the water on surface and finally reinjecting the treated water to the groundwater.
IN-SITU TECHNOLOGY: Treatment of groundwater within the aquifer utilising thermal, chemical, or natural treatment technology. In-situ generation refers back to the remedy of groundwater with out eliminating it from the aquifer . Example In-Situ methods of many type Bioremediation , Chemical Oxidation , Air Stripping , Phytoremediation and thermal treatment . The uprooted smog be recovered from the condensate or incinerated further. The addition of oxidising and reducing chemicals to the oxygen sparging process. O3, H2O2, and hypochlorite are shown in the illustration.
Adsorption that entails the passage of polluted pumped up groundwater via actuated carbon column wherein pollution get adsorbed . Techniques are used to perceive web website online traits vital to biospraging effectiveness and perceive constituent traits vital to biospraging effectiveness . Constituent concentration Of Biosparging technology range are
- •Petroleum constituent < 50,000 PPM - Biospraging Effective
Heavy metal < 2,500PPM
- • Petroleum constituent > 50,000 PPM - Ineffective
- • Heavy metal > 2,500PPM
