Modified Desalination Scheme for Handling Reject Brines

A Scheme for Large Scale Desalination

A scheme is proposed to desalinate sea water using solar energy for the Thar Desert of India. The scheme has been using solar energy for the Thar Desert of India. The scheme has been designed to produce about 5.25 x 10 m/yr (13860 MG/yr) of fresh water with 11.52 km (4.5 miles) of collector area. The solar collectors are rectangular concrete tubes, half buried in the ground, through which sea w...

Processing of Desalination Reject Brine for Optimization of Process Efficiency, Cost Effectiveness and Environmental Safety

Desalination/concentration of reverse osmosis and electrodialysis brines with membrane distillation

Brines produced by desalination processes such as reverse osmosis (RO), electrodialysis reversal (EDR) and ion-exchange (IX) holds pollution potential for the water environment if not properly handled. These brines contain a high water content (95–98%) and chemicals that could possibly be recovered for reuse. Therefore, direct contact membrane distillation (DCMD) which has the potential for wat...

Fabrication and Characterization of PES Based Nanofiltration Membrane Modified by Zeolite Nanoparticles for Water Desalination

In the present study, mixed matrix PES/zeolite nanoparticles nanofiltration membranes were prepared via the solution casting technique. The effect of zeolite concentration on the PES membrane performance and its properties was studied. Cross-sectional scanning electron microscope (SEM) observations showed that the porosity in the membrane sub-layer was increased with addition of zeolite into th...

the multi-step homotopy analysis method: a powerful scheme for handling non-linear oscillators

this paper presents approximate analytical solutions for nonlinear oscillators using the multi-step homotopy analysis method (msham). the proposed scheme is only a simple modification of the homotopy analysis method, in which it is treated as an algorithm in a sequence of small intervals (i.e. time step) for finding accurate approximate solutions to the corresponding problems. several illustrat...
