ORGANIC DILUTION

Oil sludge is a thick viscous mixture of sediments, water, oil and hydrocarbons, encountered during crude oil refining, cleaning of oil storage vessels and waste treatment. Polycyclic aromatic hydrocarbons (PAHs), which are components of crude oil sludge, constitute serious environmental concerns, as many of them are cytotoxic, mutagenic and potentially carcinogenic. Improper management and disposal of oil sludge causes environmental pollution. The adverse effects of oil sludge on soil ecology and fertility have been of growing interest among environmental scientist and an important consideration in the development of efficient technologies for remediation of contaminated land, with a view to making such land available for further use. Oil sludge can be treated by several methods such as physical, chemical and biological processes. The biological processes are mostly cost effective and environmentally friendly, as they are easy to design and implement, as such they are more acceptable to the public.

SLUDGE MANAGEMENT

Hydrocarbon sludge has various levels of solidification. Its natural properties makes it difficult to pump, move or treating the contaminant. Often the purpose of sludge treatment is to extract as much oil as possible from it, hence no oil degradation must take place during the handling. In most cases the easier way to manage the oil sludge is to dilute it with a non hydrocarbon agent such as paraffin or diesel.

ERGOFITO DIL

ERGOFITO DIL is a 100% natural mix that does rupture the bonds between hydrocarbons and other materials, such as silt, sand or clay. It separates the oil allowing it to float to the surface which eases its recovery. Additionally it will render the other above mentioned sludge components soluble, facilitating removal, pumping, separation or any other desired function.

Protocol

ERGOFITO DIL need to be mixed with water prior usage at the following ratio:

ERGOFITO DIL MIXING INSTRUCTIONS
1 Kg Mix with 1000 lt of water

Once stirred for a few minutes, Ergofito Dil is ready to be used. There are three hydrocarbon sludge classifications:

  • Fluid
  • Semi-solid
  • Solid

For the Fluid and semi-solid the Ergofito Dil application is simply pour on sludge and stir. Within a few minutes, the sludge will be liquid with all hydrocarbons floating on surface.

Solid sludge is often hydrophobic a simple mix and stirring may not be sufficient. Depending on its solidity level, it may require mechanical action, whereas it needs to be mechanically shredded together with Ergofito Dil.

The shredding action will rapidly increase surface area to Ergofito Dil, thus facilitating penetration and oil separation.

Dilution

Dilution will take place within minutes. The mix is then ready to be pumped out without risk of re-coagulation. If left standing, the hydrocarbon mixed with Ergofito Dil will naturally separate in three levels:

  • All hydrocarbons will be on the top layer
  • In the middle there will be water and Ergofito Dil
  • The bottom layer will comprise of sand/clay/ silt.
