the trend of sustainable use of available water resources encourages textile finishing enterprisesto implement efficient wastewater treatment technologies that enable water recycling, and not just it’sdischarging into the local wastewater treatment plants (wwtp). this paper presents the results obtainedfrom the h2o2/uv treatment of wastewater from slovene textile finishing company. laboratory s...
The selection of optimum high strength wastewater treatment process is complicated. Be familiar with wastewater treatment methods is not enough to design a plant. In this research, five alternative wastewater treatment methods (upflow anaerobic sludge blanket (UASB) + membrane bioreactor (MBR), UASB + Extended aeration (EA), Anaerobic baffled reactor (ABR), anaerobic lagoon (ANL) + aerated lago...
Advanced Oxidation Processes (AOPs) have been employed to degrade biorefractory organic matters. This study investigates the combination of classical Fenton reaction with electrochemical oxidation, the electro-Fenton process, for the treatment of semi aerobic landfill leachate, collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. The investigation has been carried out in batch re...
this paper presents the criteria and applied methods in the screening of potential sites for the wastewater treatment plant of the falavarjan district, northwest of esfahan province. for this the nine parameters that were selected as main criteria, 7 parameters were considered to define the buffer zones in the natural and artificial terrains. at the first stage of the study, unsuitable zones we...
the objective of this research was to develop a laboratory test procedure to predict full-scale primary clarifier performance using chemically enhanced primary treatment (cept). a method was developed that simulated actual primary clarifier performance, with chemical enhancements, based on simulating full-scale surface overflow rate (sor) and flocculation time in the laboratory. the method used...
this study examined the ability of the synthetic mordenite nanocrystal to remove tl(iii) and as(iii) from an aqueous solution. the determination of the concentration changes of h+ and oh- quantities in the acidic (ph 3) and alkali (ph 9) treated mordenite nanocrystals were done by the potentiometric titration curves. the maximum uptake capacities (qmax) of these metal ions using the mordenite i...
introduction: sequential batch reactor (sbr) is one of the modified biological treatment systems which is able to remove bod5, nitrogen, and phosphorus from wastewater. the object of this study is to determine the removal efficiency of nitrogen, phosphorus, and heavy metals from municipal wastewater by the advanced sbr system. methods: this descriptive-analytical and cross-sectional study was c...
in this research performed during 1993-1994, the effluent of behran oil refmery, in south of tehran, which produces different types of industrial oil and greases, was studied and 3 methods of gravity separation, coagulation and flocculation and dissolved air flotation were investigated. in the first phase of the survey, the quality and quantity of the effluent were determined. this showed an av...
Background and Objectives: Today, use of wastewater treatment systems in urban and rural areas is necessary to protect the health of communities, prevent water resources pollution and reuse of wastewater. Therefore, this study aimed to select the best wastewater treatment method for Meybod villages in Yazd based on analytic hierarchy process (AHP). Materials & Methods: This descriptive study w...
This data article describes a facile method for production of an adsorbent from Tamarix hispida wasted wood and modified by lanthanum metal for fluoride ions removal from wastewater. The main characteristics of the adsorbent consist of BET surface area, functional groups, and elemental analysis is presented. The data for attenuating the pollutants from a real wastewater treatment which was prov...
