SCA Invests in Anaerobic Wastewater Treatment
Mar 07 2011
The Swedish company SCA Hygiene Products, has commissioned the building of an anaerobic wastewater treatment plant at its Austrian SCA site in Ortmann. At this production site, toilet paper, serviettes and pocket tissues of brands such as ZEWA, COSY and TORK are produced from pulp and recycled paper. The order for the anaerobic water treatment went to Veolia Water Solutions & Technologies (Germany). The VWS subsidiary Veolia Water Systems Austria is building the plant in close cooperation with the wastewater specialists of Aquantis in Germany, which also is a VWS company. Aquantis is essentially handling the overall planning of the anaerobic stage according to the BIOBED® EGSB system. The plant is designed for a maximum CSB load of 16,000 kg/d and a wastewater quantity of up to 8,000 m³/d.
The commissioned anaerobic wastewater treatment is due to go into operation in August this year and will significantly ease the workload of the existing aerobic wastewater treatment plant. The core of the planned plant is an 850 m3 BIOBED® reactor in which the anaerobic pre-treatment is carried out. The energy-rich biogas arising from the process will after cleaning and drying be fed with the aid of a compressor to the works gas turbine to generate its own electricity and steam.
