Drinking rainwater - how does it work?

INTEWA, a leader in the development and marketing of water reuse systems, has successfully developed and established the AQUALOOP ultrafiltration technology in recent years. This innovative technology enables processing of rainwater into drinking water in a reliable way. The special feature of this purified rainwater source is that it is free of micropollutants such as drug residues or hormones. Not to mention pesticides such as glyphosate, which can be common in conventional water sources. Rainwater is not only an environmentally friendly alternative, but it is also low in lime and therefore particularly soft.This makes purified rainwater an outstanding resource for beer as well as lemonade production.

The treatment of rainwater using the AQUALOOP system from INTEWA is a multi-stage process that ensures that the water obtained meets the highest quality standards. First, pre-cleaning is carried out by the PURAIN filter, which effectively retains coarse contaminants. A remarkable feature of the AQUALOOP system is its ability to repel bacteria and viruses without the use of chemical additives such as chlorine, which is harmful to health.

When the water is pumped into the clear water tank, potential post-contamination of the stagnant clear water is combated by a UV system integrated into the pressure line. This disinfection measure ensures that the treated water is hygienic. The treated water is then taken to the brewery where it is brewed into beer or soda ash as usual.
