Obtaining process water out of rain from own roof with high energy saving potential compared to current processes.
Motivation and Scope
Rainwater is already chemically very pure. Only some evaporated NH3 is present. Though no salt or hardness is there. Scaling and corrosion is therefore less compared to drinking water. The used technology operates by gravity and without chemicals use. So there is no carbon- and waste footprint.
Process water made out of rain treated with membranes and a biofilter to meet process water standards. Determination of energy savings potential for applications. Evaluating several process water applications:
• Process water
• Feed water
• Boiling feed water
Preciouspitation technology can be applied on any roof. Industrial roofs have high surface areas. This combined with increasing rainfalls gives high potential to replace drinking or ground water as an industrial source.
