The basins for biological treatment of waste water are
aerated by plastic tubes on the bottom of the basins where air is inserted via slits in the
tubes. This method ensures that the bacterial cultures remain healthy and active. The bacteria
however tend to clog up the aeration slits. To prevent the bacteria to enter the aeration
slits a fine fog of water with a diluted organic acid is inserted in to the air which is
pumped into the basins.

Insertion of a fog with a diluted organic acid keeps the
aeration slits free and therefore lengthens the maintenance intervals considerably and increased
operational up-times. The acidic fog is inserted into the air ducts with special injectors
which are mounted into the air ducts
