Abwasserverband Altenrhein, Switzerland

Control system for micropollutants elimination installation (EMV) and upgrade of fixed bed biology system (FB)

In an initi­al pha­se, the FB con­trol system was upgraded. The second pha­se com­pri­sed the con­struc­tion of the 4thpuri­fi­ca­ti­on sta­ge. The new EMV instal­la­ti­on with 2 ozone gene­ra­tors and reac­tors, 4 main pumps, 8 gra­nu­lar acti­va­ted car­bon fil­ters and various ancil­la­ry systems for the 4thpuri­fi­ca­ti­on sta­ge is instal­led in a new buil­ding com­plex. The invest­ments made now allow micro­pol­lut­ants and trace sub­stan­ces to be eli­mi­na­ted in com­pli­an­ce with legal regulations.
