Water treatment for the industry and municipalities

Cost savings through RO brine concentration. Solution for TDS removal of complex waste waters. Recycle industrial effluents and reuse them back in the process. Salt concentration prior to evaporation in ZLD applications. Limit RO brine waste stream. Limit the size of your evaporator or evaporation pond.

MEGA has developed and offers its own electrodeionization units for the production of ultrapure water. This technology may be used especially in the energy industry where it may produce feeding water for boilers; furthermore, it may be used in food, chemical, and pharmaceutical industries as well as in laboratories and hospitals. The electrodeionisation effectively replaces an ion exchanger resin technology which suffers from high operation costs for the chemical regeneration of the resin itself.

Create the most advanced ZLD process using ion-exchange membranes, the only solution that brings a high reduction in capital and operating expenditures for the entire plant.

We have ZLD references from all over the world with more than 30 years of experience. Electrodialysis has been successfully used in textile, power, tanneries, breweries, chemical, petrochemical, and paper industry.

During the fertilizer production process, a waste condensate from evaporation is produced, that is discharged without further use. MEGA company has developed a unique solution based on electrodialysis technology. The concentrated condensate stream is returned back for the production of fertilizers and desalted diluate stream is re-used in the water management of a plant. The innovative technology of the company MEGA is zero-liquid-discharge (ZLD) with significant economic and ecological effects.

As for resolving environmental issues MEGA is able to demineralize efficiently even very salty sludge lake waters (TDS 30-40 g/l) resulting from mining operations or generated in the processing industry. The technology solution is operated in feed and bleed mode and it is based on electrodialysis. After passing the technology a very small volume of highly concentrated (120-150 g/l) brine and demineralized water are generated. The demineralized water may be additionally purified by means of reverse osmosis to reach values necessary for any special use.

The water from bored wells often contains more salt than allowed as to the drinking water standards or as required for industrial feeding waters (for instance for feeding of boilers). The increased salt content of groundwater water may be caused naturally or by men for instance as a consequence of excessive use of chemical fertilizers. Water from rivers or artificial lakes must be – nearly in every case – treated for drinking as well as for industrial purposes. MEGA offers technologies for the demineralization of sub-terrain and surface waters based on the principle of electrodialysis or pressure membrane processes, especially reverse osmosis.
