Analysis of distribution of oxygen transfer rate in stirred bioreactors for fungus broths 1. Suspensions of P. Chrysogenum free mycelia
Environmental Engineering and Management Journal › Vol. 9 › Nr. 2 Abstract
Unlike the P. shermanii and S. cerevisiae cultures, the study on the distribution of oxygen transfer in stirred bioreactor for P. chrysogenum free mycelia broths indicated that this process is controlled mainly by the high apparent viscosity of broths, and less by the presence of fungus biomass. For this reason, the influence of fungus accumulation on the reduction of kla is attenuated compared with that obtained for bacterial or yeasts broths. The lower influence of fungus biomass i...

STUDY ON GREENHOUSE GAS EMISSIONS FROM WASTEWATER TREATMENT PLANTS
Environmental Engineering and Management Journal › Vol. 12 › Nr. 1

One of the causes of climate change is the accumulation of greenhouse gases (GHGs). Methane (CH4) is one of the greenhouse
gases, with an ability to trap heat in Earth's atmosphere 21 times greater than carbon dioxide (CO2) per unit mass and in the same
period of time. Because the lifetime of methane in the atmosphere is relatively short, it could be kept under control.
Wastewater treatment plants (WWTPs) are anthropogenic sources of CH4 emissions. Anaerobic digestion of t... Autori: Doru Lucian Manea ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26139

Environmental Engineering and Management Journal › Vol. 19 › Nr. 11 This study shows the results of the experimental investigation of refinery wastewater treatment by the electro-Fenton process. The experiments were designed using Taguchi design approach with an orthogonal array (OA) of L16 runs. Four process variables
(current density (CD), temperature (T), Fe2+ concentration (Fe2+), and time (t)) at four different levels were considered for the present design. Regression analysis was performed to predict a correlation for the response function (chemical oxyge... Autori: Zainab I. Abbas ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28322
APPRAISAL OF HEAVY METAL CONTAMINATION IN ROAD DUST AND HUMAN HEALTH RISK IN A MUNICIPALITY OF BANGLADESH
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 Road dust from atmospheric deposition is considered as one of the significant environmental pollutants for containing toxic heavy metals. In this connection, to explore the present scenario of urban contamination and potential health risk of heavy metals present in road dust; this study was carried out in Tangail Municipality Area of Bangladesh. Road dust samples were collected seasonally from five different sampling sites encompassing different traffic homogeneity. Collected samples were proces...

STUDY ON ELECTROCHEMICAL ADVANCED OXIDATION PROCESS TO TREAT FISH MEAL INDUSTRY WASTEWATER
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 Fish meal processing industries convert the raw fish into a various commercially edible form. The effluent generated from this industry comprises a large amount of pollutants leading to high values of biochemical oxygen demand (BOD), chemical oxygen
demand (COD) and total suspended solids (TSS). Mostly traditional biological and chemical methods have been adopted to treat the effluent coming out of the fish meal industry. By using these traditional methods at the end of the process, a large amo... Autori: Rajagopalan Varadarajan ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28335
REDUCTION OF OBNOXIOUS Cr(VI) FROM ELECTROPLATING EFFLUENTS BY HYDRAZINE: KINETIC OPTIMIZATION AND MECHANISTIC MODELING FOR WASTEWATER TREATMENT
Environmental Engineering and Management Journal › Vol. 20 › Nr. 1 The simple way to deal with obnoxious hexavalent chromium is to reduce it to its trivalent form, which is comparatively less toxic. In this article, Cr(VI) was reduced to Cr(III) using hydrazine. The effect of various process parameters such as molar ratios of Cr(VI)
to N2H4, the temperature of the reaction, and the environmental chemistry of solution on the reduction kinetics have been evaluated. Experiments demonstrate an order of three for the reaction. The reaction was first order with resp... Autori: Bharti Verma ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28348 |
