Using of industrial waste materials for textile wastewater treatment
Environmental Engineering and Management Journal › Vol. 8 › Nr. 5 Abstract
Sorption is one of the several methods that have been successfully utilized for dyes removal. 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
REACTIVE DYES (R. BLUE 19 AND R. RED 120) REMOVAL BY A NATURAL COAGULANT: MORINGA OLEIFERA
Environmental Engineering and Management Journal › Vol. 14 › Nr. 10 Abstract
In this study, Moringa oleifera seed extract was applied as coagulant under different pH values (2.5 - 9.5), coagulant dosages
(200-600 mg/L), initial dye concentrations (50-300 mg/L) and different settling times (0- 60 minutes) for R. Blue 19 and R. Red
120 dyes removal. Results revealed that with increase in pH (from 2.5 to 9.5), removal efficiency decreased from 95% to 87.3%
for R. Blue 19 and from 97.2% to 62% for R. Red 120. By increasing coagulant dosage to 400 mg/L, removal e... Autori: Ali Jafari ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26864
DECOLORIZING OF REACTIVE DYES WASTEWATER VIA DOWN-FLOW HANGING SPONGE (DHS) SYSTEM
Environmental Engineering and Management Journal › Vol. 16 › Nr. 1 This study was carried out to assess the efficiency of down-flow hanging sponge (DHS) system for decolorizing the reactive dyes wastewater. The reactor was operated at different hydraulic retention times (HRTs) of 1.7, 3.5 and 6 h., and organic loading rates (OLRs) of 3.6, 2.2 and 1.3 g COD/l.d., respectively. The results obtained indicated that increasing the HRT from 1.7 to 3.6 h., significantly increased color and CODt removal efficiencies from 81±6.7 to 91.7 ±8.7% and from 24.2...

OPTIMIZATION OF ENVIRONMENTAL FACTORS FOR DECOLOURIZATION OF ANAEROBICALLY DIGESTED MOLASSES SPENTWASH
Environmental Engineering and Management Journal › Vol. 16 › Nr. 12 Fungal isolate Aspergilius niger V-8 (IITB) was isolated from the sludge of anaerobic digester of distillery wastewater treatment
plant and was found to be an appropriate fungal isolate for the purposes of decolourization of anaerobically digested molasses
spentwash (ADMS). The study aimed at optimization of the environmental parameters for achieving maximum decolourization
of ADMS using isolated fungal species. Environmental parameters like initial pH, mixing, immobilization and surfactant a... Autori: Mrityunjay Singh Chauhan ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27502
ENVIRONMENTAL APPLICATION OF Ti/TiO2 ANODES PREPARED BY DC-MAGNETRON SPUTTERING: DEGRADATION OF ACID ORANGE 7
Environmental Engineering and Management Journal › Vol. 17 › Nr. 12 Ti/TiO2 films were prepared by DC reactive magnetron sputtering followed by annealing in air at 400 ºC for 4 h. Structural tests have been performed to characterize the films, showing that the prepared films present 70% of anatase phase. When these results are compared with those from TiO2 films grown on glass substrates with similar deposition parameters, it can be seen that Ti substrates favour the formation of rutile phase, which is not observed on the films supported on glass, indicatin...
