Process for chemical decontamination of layers of earth and/or water contaminated with organic materials
First Claim
1. An apparatus for the chemical decontamination of water containing layers of earth or water from a well, polluted with organic materials comprising the following units:
- (1) a water pressure line, means for withdrawing from said water pressure line a portion of the water which portion is to be treated and returned to the layers of earth or said water well,(2) supply means for a strong chemical oxidizing agent or bactericide, means for mixing said oxidizing agent or bactericide with said withdrawn water,(3) degassing means for removal of excess gas from said water-oxidizer mixture,(4) means for distributing said water-oxidizer mixture into a plurality of supply conduits, and(5) means for delivering said water-oxidizer mixture from said supply conduits to said polluted layers or water well.

Abstract
There is provided an apparatus for the chemical decontamination of layers of earth and/or water contaminated with organic materials comprising the following block units:
Device for withdrawal of water from a water pressure line which water is to be treated and returned into the layers of earth,
A mixing device for the preparation of a mixture of water and at least one strong, chemical oxidizing agent and/or bactericide,
A degassing device for removal of excess gas from the mixture,
A distribution device for distributing the mixture to several feed lines, and
Several mobile sprinkling and/or feeding lines with drain pipes to feed the aqueous mixture to and/or the layers of earth whereby the drain pipes are at most lowered to the still water level in the water bearing layers of ground.
There is also described a method of using the apparatus.
