Currently, one of the key sectors Russian Federation is fuel industry. Oil and gas production growing annually; in 2018, 555 million tons oil 733 billion m3 were produced. The problem industry negative impact on environment, namely, activities companies produce dangerous envi-ronmental pollutants, which sludge. At same time, it a valuable raw material (potential product) that can be used variou...

As a typical pollutant, methylene blue poses serious threat to the environment and human health. Oily sludge pyrolysis residue loaded with metal oxides could be used prepare composite materials, which is not only an effective way treat oily sludge, but also possible method pollutants. In this paper, materials (AC-CuO, AC-ZnO, AC-TiO2) were prepared by residue-loaded CuO, ZnO, TiO2 directly, cha...

The performance of an aerobic membrane-coupled bioreactor (MBR) operating at mesophilicthermophilic transitional temperatures (40 ̊C) treating oily rendering wastewater has been evaluated in terms of COD, BOD5, oil and grease, solids and ammonia removal at 5 and 10-day HRT. The COD removal efficiency increased from 78% to 96%, BOD5 removal from 87 to 99% and oil and grease removal from 92 to 95%...

Field and laboratory investigations were conducted to characterize the composition of petroleum hydrocarbons in oily sludge underlying contaminated soils a decommissioned oilfield waste pit Kuwait. The results show that hydrocarbon was spatially variable. Highly toxic species such as BTEX PAHs generally lacking, both sludge- soil-borne dominated by long-chain hydrocarbons. soil contamination de...

In the global steel industry, more than 400 kg of solid byproduct is generated per ton of steel produced. Most of this by-product (70–80 %) is in the form of slag, which is used largely in the cement industry and for road and civil construction. The remaining solid by-products can be classified as dusts, sludge and oily/non-oily mill scale. Traditionally, the majority of generated dust, sludge ...
