Using of the friendly environmental chemical compounds in order to increase the rate of the sludge settling in the petroleum refineries API wastewater pounds

The oily sludge is produced by various steps of petroleum process. This sludge are contain of the crude oil and other hydrocarbons such as heavy hydrocarbons, heavy metals, insoluble Organic compounds, inorganic particles and water. The samples of these kinds of sludge's are the API wastewater pound and oily dumps that this sludge's are viscose or non - viscose. These sludge's have a lot of pollutions such as phenolic derivatives, heavy metals and hazardous organic compounds and for this reason they called Hazardous Waste. In addition to the Phenol, the oily sludge are contain of several metals such as Cd, Cu, Zn, Mn, Ni, Pb. According to the recent data, the Indian petroleum refineries produce about 28000 ton of sludge per year that this amount of sludge is one of the most important problems for them and they have had serious environmental problems for disposal treatments. Dewatering and concentration of the sludge's are very difficult that is related to their colloid properties and for that the settling of the sludge's are difficult and need to a long time for it. In this study we introduce a new method for fast settling of the sludge's in the petroleum refinery API wastewater pounds or anywhere else with using of the friendly environmental chemical compounds.
