DEWA - an exclusive energy effective technology for desalination of water of any saltness. NO membranes, NO filters, LOW energy consumption.

1. DEWA DESALINATION of SEA & ANY OTHER WATER New World Technologies

4. Desalination: DEWA & others Moscow, Russia Amalthea, Group of Companies www.dewa.ru Coarse filtering Disinfection Fine filter RO Coarse filtering Evapouration Coarse filtering DEWA RO (reverse osmosis) Boiling & evaporation DEWA

5. DEWA: comparing with other methods Moscow, Russia Amalthea, Group of Companies www.dewa.ru *Important note! Most of distillers are not suitable for desalination of salt water, only for distilling tap water! **Parameter calculated according to known data for steam desalination plant. *** Parameter value now. To be improved in close future. RO (reverse osmosis) Boiling distiller* DEWA Pre-filtering Required Required Required Disinfection Required No No Fine-filtering Required No No Desalination quality 99.4% average, 100% H2O Salt: <10g per liter 100% H2O Any (!) % of salts Scurf&sediments Yes Yes No (!) Dependence on % of includes in water Yes, strongly depends Scurf dramatically grows if % of salt is high Almost no dependence Cost Price of 1 l € 0.02 + pre-treatment € 0.10** Grows if required high production € 0.021*** (Price of 0.67 kW*h)
