Hybrid process

This study is focused on the application of the ion exchange Á submerged microfiltration hybrid process for boron removal from geothermal water containing high level of boron (8 Á 9 mg B/L). The goal of this study is to determine the optimum parameters such as feed flow rate, resin concentration and

Hybrid-pervaporation-distillation processes have been intensely studied in the last years and considered as a good alternative in the separation of homogeneous azeotropic mixtures. Compared with the techniques in use in the chemical industry, they can reduce the energy consumption and avoid the use

The hybrid process of seawater desalting couples the reverse osmosis with the multi-stage flash process. The hybrid process is usually planned to improve the performance of MSF and reduce the cost of desalted water. Most of the studies on these plants refer to the parameters (both technical and econ

The advanced separation process for boron removal has been put forward by combining boron sorption on a fine powdered boron selective resin (BSR) with a complex separation on microfiltration membranes. The proposed membrane-based hybrid process integrates in one step sorption efficiency of the selec

T reatment of sewage plant effluent by simple nanofiitration seems to be limited by organic fouling and only possible with extensive chemical cleaning. ............................................................................................................................

Characteristic features of ultrafiltration water treatment and water treatment using ultrafiltration in combination with complexation for water polluted with U(VI) were investigated. Polyethylenimine (PEI) was used as the complexing agent. The relationship of U(VI) removal as a function of pH and th

Electrodialysis (ED) is an efficient process for the treatment of drinking water with high nitrate concentration. However it achieves only a transfer of pollution by producing concentrated brines. This study demonstrated the feasibility of ED brine denitrification in a membrane bioreactor (MBR). The

The technical and economical feasibility of inorganic membranes was evaluated for the dewatering of organic solvents by pervaporation. A mapping of the process industry was carried out in order to examine the most attractive applications. The performance of an amorphous silica membrane was screened

A new hybrid gas separation process combining membrane permeation and pressure swing adsorption (PSA) is presented. An integrated model was formulated which successfully predicts all process characteristics. Our modeling work shows that the coupled process increases the efficiency of the pressurizat

An in-line coagulation (without settling)/UF process has been studied to improve membrane performance and water quality for surface water treatment. Using coagulation before UF increases permeate quality; the extent of dissolved organic matter removal is controlled by the coagulation step. Efficient
