2REMEDIAL TECHNOLOGIESIn Situ OxidationThe technology is mainly applied in the removal of organic contaminants such asToluene, Ethyl benzene, Benzene and Xylene.The oxidising compound is usually injected into the source of the contaminant. .The chemicalreactions of the oxidising agent destroys the contaminants. The technology is designed in a way to enable the extraction of the excess oxidiser compound and the oxidised contaminants through the usage of the water treatment zone. In most cases hydrogen peroxide has been used as an oxidising agent (Reible, D., 2013 p 28).The technology which is mainly based on the chemical principles of the robust oxidising agent to destroy the contaminants in their sources can be used to control the spread of the pollutants in the storage tank by the use of ground water as a media.The diagram below clearly shows on how the technology is used.Process diagram for in situ oxidation
3Pump and treat remedial technology.The technology is applied in removal of both organic and non-organic contaminants in the ground water. The contaminated ground water is pumped from the subsurface and the treated before it is discharged hence the name Pump and treat technology. It one of the most common used redial technology in the ground water.In the cases where the contaminant is not dissolved it can not cause any effect to the quality of the ground water. In the cases where the main contaminant source is not previously removed, the remediation technology can be very expensive and time consuming. This remediation technology is usually affected by the ground water hydraulics because of the abatement which are generated when there is a constant flow (Reible, D., 2013 p 164).The main benefit of this remedial technology is that it provides both the ground water restoration and the hydraulic interception of the barrier and also provides protection of the potential receptors this technology can be used in the lagoon for the removal of the contaminants. The diagram bellow is an illustration on Pump and treat remedial technology works.
