New hydrochloric acid system in Ryaverket, Sweden

On a typical day, just over 4,000 litres of wastewater comes in every second to be treated in several stages before being released into the sea. In terms of quantities of wastewater, this makes Ryaverket the largest sewage treatment plant in the Nordic region. 

The final treatment stage consists of the water being forced through disc filters to remove the tiniest particles, including phosphorus.

The filters require regular washing with hydrochloric acid to maintain their function, and now Ryaverket has gained a brand new hydrochloric acid system to ensure better function and greater safety in the handling of the corrosive hydrochloric acid.
