## Solar Powered Water Treatment & Purification Plant

The solar-powered water treatment and purification unit is an autonomous and portable element designed to produce potable water for human and/or agricultural use, from brackish, seawater, or contaminated water, with no need of any external artificial energy source rather than the sun, thanks to the solar panels built-in.

These systems incorporate their own chlorination system, also powered by the same FV panels, thus outgoing water is already protected by a 0.5 g/m3 chlorine.  It is important to highlight that, besides contaminated salts, viruses and bacteria are also eliminated as they can’t go through the membranes.

There are three basic sizes, one for each type of water to be processed and a fourth one to be used as emergency unit” that will include the main elements of the first three to be chosen when there is no time or resources for a previous analysis of the existing water. APPLICATIONS AND DIFFERENT SET-UPS As per the type of water
• SEA WATER
• SWEET CONTAMINATED WATER
• SALINE WATER
• EMERGENCY UNIT (ALL INCLUDED)
