BACKGROUND In Iran, re-refinery industry has been developed many years ago based on the acid-clay treatment. Acidic sludge with high concentration of total petroleum hydrocarbon (TPH) is the final products of some facilities. In this study removal of TPH by aerated in-vessel composting was investigated. METHODS In order to microorganisms seeding and nutrient providing, urban immature compost ...

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...

Owing to the importance of clean and fertile agricultural soil for the continued existence of man, this study investigated the concentrations of total petroleum hydrocarbons (TPHs), polycyclic aromatic hydrocarbons (PAHs) and some heavy metals in soils and selected commonly consumed vegetables and tubers from oil-polluted active agricultural farmland in Gokana of Ogoniland, Rivers State, Nigeri...

Petroleum exploitation in oilfields, especially drilling, generates an oily sludge mixed with hydrocarbons and mineral solids. This oily sludge is sometimes treated by bioremediation and phytoremediation. This investigation established that landfarmed oil sludge provided adequate soil conditions to grow jack beans (Canavalia ensiformis) that in turn rhizoand phytoremediated residual aliphatic a...

The ecotoxicological effects of oil spill from the grounded vessel MV River Princess on the intertidal benthic organisms of Sinquerim-Candolim beach at Goa were investigated. An intertidal expanse of 1 km on either side of the grounded vessel was selected to evaluate the concentration of total petroleum hydrocarbon (TPH) in the sediment and its effects on the composition, abundance and diversit...

Crude oil pollution is an endemic environmental problem in the Niger Delta region of Nigeria with background levels greater than regulatory intervention limit 5000mg/kg soil as stipulated Environmental Guidelines and Standards for Petroleum Industry (EGASPIN) most polluted sites. Hence, essence this study was to evaluate extent damage caused by pollutant (crude hydrocarbons) on physicoch...

The presence of earthworms in soil contaminated with petroleum products (PPs) increase the rate decomposition. use more than one animal species simultaneously remediation could accelerate process. However, effects may be different when long-term aging contamination exists during which toxic by-products can formed. This study evaluated effect PPs (petrol, diesel fuel, and used engine oil) carrie...

the contamination of soil and water with petroleum hydrocarbons is a widespread environmental problem. the treatment requirement and removal of this pollutant are becoming more important in these days. total petroleum hydrocarbon (tph) has been reported to be toxic, carcinogenic, and an endocrine disrupter widely used in developing countries. various physical, chemical, and biological methods w...

Gasoline vapor was treated using a compost biofilter operated in upflow mode over 4 months. The gas velocity was 6 m/h, yielding an empty bed retention time (EBRT) of 10 min. Benzene, toluene, ethylbenzene and xylene (BTEX) and total petroleum hydrocarbon (TPH) removal efficiencies remained fairly stable approximately 15 days after biofilter start-up. The average removal efficiencies of TPH and...
