Petroleum sludge and other forms such as coal tar is a complex emulsion of various petroleum hydrocarbons (PHCs), water, heavy metals, and solid particles. 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. It also affects the soil fertility. The ECOS/Bio-ART Treatment of waste oil hydrocarbons is the most cost effective method of remediation by the use of aerobic fermentation, a process that does not include physical or chemical process.
The ECOS/Bio-ART aerobic process serves as remedy to treat the sludge by maintaining factors such as nutrients, pH, moisture, aeration and temperature within the fermentation system. If required a bulking agent will can be used. The high microbial diversity and activity during fermentation, is due to the abundance of substrates in feedstocks that promotes degradation of xenobiotic organic compounds, such as pesticides, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). The unique selection and combination of microorganisms supplied with the ECOS/Bio-ART system bio transform pollutants into non-toxic or less toxic substances.
All hydrocarbons are fermentable and with the introduction of the proper microbial diversity the ECOS/Bio-ART fermenter will efficiently metabolizable carbon and the degradation of xenobiotic organic compounds.
Polycyclic aromatic hydrocarbon is one of a class of chemical compounds and organic pollutants. PAH constituent of the oil sludge poses a serious threat to environment can render harm to humans, livestock, wildlife, crops, or native plants. A lot of physical, chemical and biological methods have been developed but none is as economical and environment friendly as the ECO/Bio-ART technology.
Present installations have demonstrated that the ECOS/Bio-ART technology degrades or binds pollutants to innocuous levels or into innocuous compounds and has shown the ability for remediation of other polluted materials. Treatments facilities in S Korea utilize the ECOS/Bio-ART technology on petroleum oily sludge. Approximately for every 15 tons of process input yield 5 ton of output. Depending on the heavy metal content the output is used as fertilizer or as a Biomass replacement for coal.
