I% there is no a""r#in$ wastewater %or lon$er periodthe "ontrol system o% the plant "an be swit"hedinto holiday mode. his way the aeration o% the

    'ed-bed is red#"ed to 7, 8 o% the normal ele"tri"ity "ons#mption. When $ettin$ba"2 to normal operatin$ "onditions the ori$inal p#ri"ation "apa"ity is a"hie1ed ina %ew days by the %ast rea"ti1ation o% ba"teria.
