Manual water treatment plant

OASIS

Manual water treatment plant operating on the reverse osmosis principle, designed for preparation of safe water from polluted water sources in emergency situations, intended for individuals or small groups of persons, in critical areas without access to electricity connection

 

Oasis can provide treatment of polluted water in the amount of up to 6 l/hr with the following efficiency:• Non-dissolved substances (it is recommended to let the settling part settle) .100 %
• Small water organisms that do not settle . . . . . . . . .. . . . . . . . . .100 %
• Algae and cyanophytes . . . . . . . . . . . . . . . . . . . . . . .100 %
• Any bacteria and viruses .100 %
• Substances dissolved as ions up to 3,000 mg/l . . . . .. . . . .. . . . . . . .90 %
• Organic contamination of surface waters upon settlement . . . . … . . . .90 %
• Faecal contamination up to 80 mg/l of chemical oxygen demand, 10 mg/l NH4+ and 2.5 mg/l NO2- . . 85 %
• Heavy metals .99 %
• Organic contaminants of the PCB, PAH, HCH types and other organic pesticides . . 95 %
• Non-volatile war poison substancesOasis is a compact water treatment plant adapted for movement within the terrain – the whole technol¬ogy is situated in the practical firmed backpack with adjustable arm straps.The water treatment plant consists of a waterproof bag for raw water, manual pump, prefilter with the filter bed, pressure vessel with the RO module, control valves and a cartridge with remineralizing tablets.Oasis has been designed for operation without any maintenance and without any need of replacing the filter bed and the RO module for months.The life-time of the filter beds and membranes depends in es¬sence on the raw water quality.Operating Oasisis very easy and consists in filling the waterproof bag with raw water and in pumping the manual pump subsequently in order to produce sufficient amount of the water.The remineralizing tablet containing minerals necessary to renew the biological value of drinkable water treated by means of reverse osmosis is to be added to the
