In the paper the problem of excessive sludge anaerobic stabilization process intensification by combined pretreatment method i.e. alkaline hydrolysis and ultrasonic field active action was discussed. Combination of the mentioned methods, base on different mechanisms of action allow to obtain high pr

In this study, two activated carbons were prepared from loofa, loofa carbon-1 (LC1) and loofa carbon-2 (LC2). The surface structure of LC1 and LC2 were analyzed by scanning electronic microscopy (SEM). The ability of LC1 and LC2 to remove reactive orange (RO) dye from aqueous solutions by adsorption

The SAPO-5 zeolite-filled polyurethane membranes with perselectivity to the gases or liquids were prepared, characterized and utilized for the ultra- and, respectively, microfiltration (UF + MF) of synthetic wastewater containing colophony. The influence of the colloidal dispersion concentration on

Micellar enhanced ultrafiltration (MEUF) was used to remove cationic dye from aqueous solution. Sodium dodecylsulfate (SDS) and Safranin T (ST) (molecular weight 350.85) have taken as anionic surfactant and cationic dye, respectively. Regenerated cellulose membrane of molecular weight cut-off 10 kDa

The textile wastewater treatment by membrane processes presents some limitations such as membrane fouling which causes a rapid flux decline. In fact, the membrane processes efficiency can be affected by membrane pore blocking or/and cake formation. In order to limit the effect of membrane fouling ca

Water co-produced with oil and gas is termed produced water. Produced water is very difficult wastewater to treat and characteristics changes by well to well. In this study, treatability of produced water generated from oil production fields in Trakya region which is operated by National Oil and Nat

In this paper a methodology for MSF process optimization taken into account process availability will be presented. The process optimal operative conditions, and the optimal equipment allocation in stand-by units when necessary will be performed, given a process model and cost data. In this paper a

A process optimization method has been developed for the design of reverse osmosis (RO) processes. RO process configurations are systematically generated using a flexible superstructure and evaluated by economical (investment and operating costs), technical (energy requirement, water recovery rate)

Several studies have demonstrated that the performances of combined cycle power plants can be optimised taking advantages of flue gas waste heat. However, despite the process advantages related to power cycle have been clearly identified no judicious use of flue gas heat to enhance performances in t

The aim of the present study is to bring in our modest contribution in evaluating the water state in the sources that feed Constantine city. For the purpose of quality determination, analyses based on the measure of some physico-chemical and bacteriological parameters have been realized on samples t
