A large number of materials have been used as suitable sorbents for decolourization of industrial effluents: activated carbon (the most common but expensive adsorbent), polymeric resins, various low-cost adsorbents (agricultural and industrial by-products, peat, chitin, silica, bentonite, other clays, fly ash).
Our paper is a review about our researches regarding different types of industri... Autori: Daniela Suteu, Carmen Zaharia, Augustin Muresan, Rodica Muresan, Alina Popescu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25532
Adsorption characteristics of Co(II) ions from aqueous solutions on romanian peat moss
Environmental Engineering and Management Journal › Vol. 8 › Nr. 5 Abstract
Peat moss has been widely used as low-cost adsorbent to remove a variety of pollutants, including organic compounds and metal ions from aqueous effluents. Various functional groups allow such compounds to bind on active sites of peat moss. The adsorbent used in this study was Romanian peat moss sampled from Poiana Stampei (Romania). The adsorption of Co(II) ions from aqueous solutions on Romanian peat moss was studied in batch experiments, in order to establish the influence of initi...

Environmental Engineering and Management Journal › Vol. 10 › Nr. 12 An increased level of environmental awareness by consumers has caused marketing to pay special attention to the deteriorating environment. This is a consequence of markets punishing those companies that fail to consider environmental concerns in their marketing efforts. However, how environmental proactivity is integrated into marketing strategy has been scarcely analyzed in the marketing literature. The present paper aims to fill this gap in the literature by theoretically analyzing the ways in...

as a by-product found when these drugs are obtained via the Leuckart method. Also, pyridine is well known as a biomarker of
microorganisms, when those are subjected to pyrolysis before analysis by various instrumental techniques. Consequently, since
Py is not commonly found in the air, its presence as a contaminant at trace levels in a room could ind... Autori: George-Bogdan Ghira ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26109

ROOT SYSTEM CHARACTERISTICS OF THREE WOODY SPECIES PLANTED ON STEEP SOIL-DENUDED SLOPES
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 This paper aims to investigate the root characteristics of three woody species (Pinus brutia, Quercus coccifera and Spartium junceum) planted on steep soil-denuded slopes, surfaced after ring-road excavation. The planted slopes were almost vertical, south faced and adding no soil. Fifteen plants per species were manually extracted for root system analysis and testing. The findings showed that the survivorship was different among the investigated species with S. junceum plants to survive better. ...

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
OPTIMIZATION OF THE EVACUATION ROUTE IN CHEMICAL PLANTS BASED ON THE DEPTH-FIRST SEARCH ALGORITHM
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 Optimal evacuation routes are crucial to protect workers’ safety when accidental leakage of toxic gas occurs in chemical plants. However, the majority of route optimization focuses on the transport field and few on the evacuation routing optimization in chemical plants. This paper proposes a dynamic evacuation routing optimization method for chemical plants under toxic gas release scenarios. From the complete accident scenario set (CASS) built with wind fields and leakage sources, the leak... Autori: Ying Liu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28336
ASSESSING THE USE OF ELECTRIC SCOOTERS AND ITS ASSOCIATION WITH PERSONALITY TRAITS TO ADOPT PRO-ENVIRONMENTAL BEHAVIORS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 The paper analyses the Romanian consumer’s behavior concerning the use of electric scooters for transport. The aim of the study is to investigate Romanian youths’ intentions regarding the use of electric scooters in the development of a sustainable behavior. The
present article is based on a quantitative research, coordinated by the authors, conducted among young participants from Romania. A questionnaire was created using a set of items measured on a five-point Likert scale, on the... Autori: Ana-Maria Ionescu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28338
Larus relictus HABITAT HIERARCHICAL EVALUATION BASED ON A DATA DRIVEN APPROACH
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 The application of Species Distribution Models (SDM) in the management of species habitat and environmental impact changes has been widely used by scientists and ecologists globally, however this study proposes a novel analytical technique involving the combination of a statistical ranking algorithm and Remote sensing GIS data (habitat and threat) to analyze the suitability hierarchy of the habitat of a signature water-bird (Larus relictus). The results indicate that about 47.63% of the study re... Autori: Harrison Odion Ikhumhen ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28339
EXPERIMENTAL ANALYSIS OF INNOVATIVE HEAT EXCHANGER WITH UNIFORM HEAT FLUX USED IN HEAT PUMPS SYSTEMS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 The study presents the experimental testing of a heat exchanger with uniform thermal flux (HEUTF), used as a cold source in HVAC systems with heat pumps. A water-water heat exchanger is tested, having a special geometry, with uniform thermal flux along the system. The heat exchanger proposed consists of a distributor and a collector, connected to each other by means of 20 staggered copper pipes, being suitable for serving low or medium geothermal sources. The innovation consists in the uniformit... Autori: Sebastian Valeriu HudiČ™teanu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28340
