Oily sludge purification and market application


 

What is oil sludge:
 

Oily sludge is refers to the soil contaminated by petroleum, mineral oil or any other kinds of Oil pollutants, in many cases it is refers to the petroleum contaminated soil.

Oily sludge is caused by the leak or spill of petroleum during the drilling, transportation, storage and usage of the petroleum, once the oil enter the soil, it will destroy the Natural dynamic balance of the soil and causing Dysfunction and degradation of soil quality.

 

 



Hazards of the oil sludge:
 

1.Effects on soil microorganisms:Causing the variation of microbial community and micro flora within the soil.

2.Effects on crops:affect the growth of crops by reducing the budding rate,delaying the growth period and lowering the fruit rate of crops. All of these factors will directly leads to crop yield reduction and serious affected the quality of crops.

3.Effects on physical and chemical properties of soil:When the petroleum substances enter the soil, it will cause changes in the physical properties of the soil, such as clogging the soil pores and changing the composition and structure of soil organic matter.

4.Effects on Humans and animals:Petroleum contain aromatic hydrocarbon which is extremely harmful to human and animals.

5.Effects on soil enzyme:Change the living conditions of soil enzymes and effect the catalytic efficacy of enzyme.

PS:

  √ Currently the best technology in china can reduce the Petroleum content to 1%.

  √ Agricultural usage standard require the Petroleum content must be less than 0.3%.

  √ The Electric-catalytic water technology can reduce the Petroleum content to less than 0.04%.

 

Introduction of oily sludge purification technology
 


Electro-catalytic water:

 

The Electro-catalytic water is produce by the SEEF technology. Certain modification of the equipment can allow us to control the equipment to produce different kind of Electro-catalytic water, such as alkaline, acidic and neutral electro-catalytic water. In the mean time, the equipment will enrich the water with a vast amount of free radicals and adjust the PH value and EH value to fit our need.


The application of electro-catalytic water:


A:Neutral electro-catalytic water: It mainly use in the treatment of TVOC contaminated soil, oil contaminated soil and chemical pesticides contaminated soil.


B:Acidic/Alkaline electro-catalytic water: Can efficiently decompose the pollutants of all kinds of oil contaminated soil.
