AQUA HS

The mobile drinking water unit for water with high salinity is a containerised compact unit able to solve both permanent drinking water shortage problems and to provide for temporary needs due to natural disasters or emergencies.
The unit is capable of removing from water various contaminations due to suspended solids, salts, organic and chemical micro pollutants, bacteria and make it suitable for human consumption, according to the drinking water parameters guidelines set by WHO.

DESCRIPTION AND APPLICATION PROCESS

The unit is composed mainly of one or more 20' and/or 40'containerised modules that will be, time by time, tropicalized, insulated and conditioned according to the environment and the working condition. Time by time the unit could be equipped with a autonomous power generator unit, automatization and computerized control of the process. The turbid water, drawn from the river and/or lake by motor pumps is pumped in the first chemical conditioning and mixing compartment, then by gravity passes in the second flocculation compartment and the following compartment with lamella settling. Raw water, coming from wells and/or lakes, having low turbidity or with most of suspended solids being removed in the treatment previously described, is stored in an intermediate disinfections and storing tank. The storing is able to allow a suitable contact time for disinfections and enough storing volume for filters washing. Disinfected water, by motor pump, is pumped in one or more sand and/or activated carbon filters, for removing on the sand bed residual suspended solids and on the activated carbon bed organic micro pollutants and chlorine. By means of the residual pressure water passes first through a cartridge filter and then in a second storing tank. In this tank water is again chemically conditioned and caught by variable pressure motor pump with frequency converter. Pressurized water is then pumped in reverse osmosis for the required desalinisation and then, if required, goes to the final treatment of chemical conditioning and bacteria contamination removal by UV. The system is always equipped with units for storing and dosing chemicals, automatic filters washing and UV system for removing bacteria contamination. After UV treatment will be available water complying with the parameter set by WHO.
