Oilfield water treatment techn

The use of water in the oil field to enhance oil recovery process, due to water frequently contains a small amount of sulfide, bacteria and other insoluble material, long-term use not only water pipeline wall erosion, but also in the wall would have included curing of ferrous dirt or sludge, reducing the permeability around the borehole and the injection efficiency. Usually by water injection wells and production of treated sewage effluent from two parts, in actual operation, there appeared water wells and the production of sewage is not the phenomenon of compatibility, it is because the two in terms of surface or underground water mixed with a generating FeS precipitation trends. To address this problem, my company applied chlorine dioxide technology, chlorine dioxide disinfection, in addition to sulfur ions, stripping dirt and other effects used in the production of the oilfield wastewater treatment process, so that oil production can return to treated wastewater use.

Chlorine dioxide is an oxidizing bactericide, its mechanism through the release of a new ecology of oxygen play a killing effect on the microbial cell wall have better absorption and penetration performance, to be effective in oxidation of intracellular sulfur based enzymes to rapidly inhibit cell protein synthesis, so that the amino acids in protein oxidation and decomposition, which will kill the fungi break down. When the bacterial concentration of 105 ~ 106 / ml,, ClO2 for 5 minutes and will kill more than 99% of the heterotrophic bacteria; in pH, within 5 to 9 have a strong bactericidal effect, will soon be able to sulfur ions (S2-) oxidized to sulfate (SO42-). Sulfate can be soluble in water.

Addition to the application of chlorine dioxide technology, to address the oil field production water, ground water corrosion, scaling and so on, my company with the investment plus water treatment chemicals, oil field re-injection or discharge water compliance.
