Efficiency in removal of chemical and biological substances
One of the more efficient system for water treatment is filtration on membrane, with different techniques, as ultrafiltration, nanofiltration and reverse osmosis, and on sand and carbon beds, as multimedia filtration.
What about applications?
The need of maintenance and periodic replacement of membranes is the factor that weights mostly on operating costs. By application of innovative technologies, in any case, it is possible obtain a reduction of mineral scaling and a lowering of energy consumptions.
In water scarcity situations, for water potabilization can be employed mobile reverse osmosis units, that through connection with a photovoltaic system are able to reach energy autonomy.
