Stormwater pollution is a major cause of water quality impairment. Much the existing gray stormwater infrastructures provide little or no treatment, especially for dissolved pollutants. Due to capital cost installing new infrastructure, retrofitting promising alternative reduce pollution. In this study, aluminum-based drinking treatment residuals (WTR), byproduct from was combined with other co...
The biota in the Arabian Gulf faces stress both from natural (i.e., hyper salinity and high sea surface temperature), and human (i.e., from oil-related activities) sources. The western Arabian Gulf was also impacted by world’s largest oil spill (1991 Oil Spill). However, benthic research in this region is scarce and most of the studies have been conducted only in small areas. Here, we present d...
This study was carried out for remediation of drill cutting soil from two oil field sites in Kurdistan Region Iraq. nanotechnology implemented. Heavy metal (Pb, Cd, Cr, Ni and petroleum hydrocarbons (C8-C24, C24-C40, TPH) were analyzed before after soil. The experiment designed. results indicate that the concentration heavy metals (Ni, Cd Cr) within normal range except Pb. result showed removal...
Produced water (PW) and spent oil-based wastewaters are some of the largest mineral oil produced. Due to high toxicity hydrocarbons, several countries set stringent discharge limits its treatment is compulsory before discharge. In this work, biological coupled with production bacterial lipids demonstrated in sequential batch airlift reactors (SBAR). Two SBAR (2 L working volume) were used for P...
Earlier phases of economic expansion and urban development have resulted in significant sources of urban soil contamination. Petroleum hydrocarbons are one of the most common groups of persistent organic contaminants in the environment. In this study, two types of treatment in 3 concentrations were prepared that were included plant treated by 1% oil pollution, treatment by 1% contamination with...
This work aimed to evaluate the capability of different microorganisms to degrade commercial diesel oil in comparison to a weathered diesel oil collected from the groundwater at a petrol station. Two microbiological methods were used for the biodegradability assessment: the technique based on the redox indicator 2,6 -dichlorophenol indophenol (DCPIP) and soil respirometric experiments using bio...
The present study reports the level of total petroleum hydrocarbon (TPH) in 27 commercially important fish, crustaceans and cephalopods from Orissa coast, Bay of Bengal to provide the baseline data for oil contamination in marine biota. The results showed significant differences in the TPH concentration in different species. Of all fish, Carangoides malabaricus showed the maximum TPH level (av....
The feasibility of total petroleum hydrocarbon-contaminated (TPH) soil remediation was studied using persulfate oxidation. Factors tested included type of activator, persulfate concentration, number of persulfate applications, and reaction time. Probe chemicals were used to study effi ciency of the persulfate oxidation mechanism. The best activation method used Fe2+, which achieved 40.8% TPH de...
Soil pollution caused by oil leakage from various industrial facilities such as gas stations, plants, military bases, and railway depots has become a serious global environmental geotechnical issue. The indirect-heated microwave thermal desorption technology been developed in this study for economical efficient remediation of or organic pollutants. conclusions were made based on laboratory test...
