The assessment of the quality of carwash effluents has received scant attention as a potential source of public and environmental health hazard in South Africa as demonstrated by the lack of literature in this subject. The physicochemical quality and potential ramifications of carwash effluents on receiving waterbodies were investigated in this study. Grab effluent samples were collected from s...

Vegetable oil and grease polluted wastewater caused many problems in wastewater plan such as physical blockages in sewer, pump, screens and filter distributor arms. Its occurrence in effluent increase COD significantly even its amount is not high. In this paper, bioremediation was investigated to remove vegetable oil and grease. Four strains were positive with lipid degrading test. Cell morphol...

The study aimed to determine the efficiency of a wastewater treatment plant and quality effluent discharged by into receiving water body (Okochiri River) in Eleme, Rivers State. lasted for four months. Wastewater samples were collected at various stages unit tested major parameter such as Biological Oxygen Demand (BOD), oil/grease, phenol, Dissolved (DO), Total Suspended Solids (TSS), sulphide....

The shaft deflection is one of critical factors that deteriorate the grease lubrication state inside the tapered roller bearings (TRBs). So, in this paper, on the premise of the TRB subjected to the combined loads and the shaft is deflected, the grease lubrication model at the TRB contacts was constructed, in which the interaction loads, linear and angular displacements of the bearing parts wer...

The film thickness decay of grease-lubricated bearings is determined by a loss lubricant from the bearing. One these mechanisms base oil evaporation. In this article, model presented for evaporation where volatiles leave bearing breathing. applied to typical drive cycle temperature varied in time. impact volatility oils and quality sealing on losses can be quantified with model.

Produced water is present in oil and natural gas reservoirs transported to the surface along with oil. Total grease content (TOG) main parameter evaluated this waste disposal category. Today, validation of methods laboratory not done using petroleum. The objective work was develop synthetic oily standards that can be applied for internalization laboratory. Oil weighing protocols, influence vola...
