Desalination By Electret Technology
A purification process of making use of electret technology for efficient but cost effective deionization was discussed in this paper. Douglas MacGregor claimed that PTFE electret works as a means of ions separation for desalination due to the polarization of an electrolyte and ions migration under a permanent electrostatic field generated by a pair of electrets with opposite polarities.

Characteristics And Application Of Multiple Membrane Process In Plating Wastewater Reutilization
A multiple membrane process aimed at reutilization of plating combined wastewater after physical and chemical pretreatment in mechanical industry was developed for selective separation to reduce cost and mitigated the increasing heavy metal pollution. The process was divided into three stages: firstly, microfiltration (MF) and ultrafiltration (UF) was used to separate the possible organic and suspended matters, secondly, electrodialysis (ED) was carried out for effective desalination, and thirdly, the concentrate from ED was treated by nanofiltration (NF) and reverse osmosis (RO) separately to increase the recovery rate of water.

Bromide And Iodide Removal From Waters Under Dynamic Conditions By Ag-Doped Aerogels
The objective of this study was to analyze the efficiency of Ag-doped aerogels in the removal of bromide and iodide from water. To test the applicability of these aerogels in water treatment, adsorption of bromide and iodide was studied under dynamic conditions using waters from Lake Zurich and a mineral water. The results obtained by using these waters showed a high breakthrough volume (V0.02 = 0.4 L) of the columns, while the height of the mass transfer zone (HMTZ = 6.8 cm) was low, regardless of the anion under study. Bromide- and iodide-saturated columns were regenerated with NH4OH. No change in the column characteristics was observed after two regeneration treatments, regardless of the type of water considered

Capacitive Deionization As An Electrochemical Means Of Saving Energy And Delivering Clean Water. Comparison To Present Desalination Practices: Will It Compete?
Potable water as well as water for agriculture and industry is critical to human habitation on this planet. We have been squandering and polluting this precious resource and are now in need of finding cost competitive newer technologies for reclaiming this valuable life-sustaining liquid. Capacitive deionization (CDI) is an electrochemical water treatment process that holds the promise of not only being a commercially viable alternative for treating water but for saving energy as well.

Biofilm Growth From Wastewater On Mwnts And Carbon Aerogels
Introduction Wastewater resulting from different
industries is nowadays of great concern as it poses not only severe risks to human health, but also potentially unacceptable ecological risks to plants and animals. With the increasing demand for economic large-scale water treatment applications, the development of novel, low-cost and efficient treatment technologies is of great significance.
