Sulzer Turbocompressors for Clever Wastewater Treatment in a Pulp and Paper Mill


Norske Skog Boyer Mill in Tasmania is a TMP newsprint mill that has produced paper continuously since 1949. A wastewater treatment plant comprising a central moving bed bioreactor (MBBR) and outer activated sludge tank (AST) treats up to 25,000m³/d of process effluent. Four sets of turbocompressors type ABS HST play an essential role in the supply of air for efficient aerobic biological treatment.

The compressors feed nine units of Submersible aerator mixer type ABS OKI in the AST and the aeration grid in the MBBR.
