Electrocoagulation process using high current intensity to treat palm oil mill effluent(POME) was investigated in this *** operating parameters such as electrolysis time, inter-electrode distance and initial pH were carried out to determine the efficient process condition on the removal of chemical oxygen demand(COD),biological oxygen demand(BOD) and suspended solids(SS).The highest treatment was achieved at 50 min with the removal efficiencies for COD, BOD and SS obtained as 85%, 83%, and 84%, *** than 50 min treatment showed the fluctuated trends of removal efficiencies which can be considered *** application of higher current resulted in higher removals of organics while the gas bubbles also assisted in removing the pollutant particles by *** an inter-electrode distance study, the removal efficiency decreased when inter-electrode distance was either higher or lower than 10 mm due to the increase of solution resistance and the decrease of anode active surface *** initial pH study, it was found that high removal efficiencies were achieved in slightly acidic POME sample rather than in neutral or basic *** electrocoagulation process by using the optimum operating parameters was able to remove COD, BOD and SS up to 95%, 94% and 96% *** experimental results confirm that application of high current intensity in electrocoagulation provided high treatment efficiency at a reduced reaction time.

Abstract Different organ preservation methods are key factors influencing the results of fiver transplantation. In this study, the outcomes of experimental models receiving donation after cardiac death （DCD） livers preserved through machine perfusion （MP） or static cold storage （CS） were compared by conducting a meta-analysis. Standardized mean difference （SMD） and 95% confidence interval （CI） were calculated to compare pooled data from two animal species. Twenty-four studies involving MP preservation were included in the meta-analysis. Compared with CS preservation, MP can reduce the levels of aspartate aminotransferase （AST）, alanine aminotransferase （ALT）, lactate dehydrogenase （LDH）, and hyaluronic acid （HA） and the changes in liver weight. By contrast, MP can enhance bile production and portal vein flow （PVF）. Alkaline phosphatase （ALP） levels and histological changes significantly differed between the two preservation methods. In conclusion, MP of DCD livers is superior to CS in experimental animals.
