摘要：
Many pulp mills are looking to improve their wastewater treatment Systems because of mort restrictive environmental regulations coupled with increased pulp production. Oxygen based systems enable pulp mills to meet these growing needs. The use of an efficient oxygen mixing system, such as Praxair's I-SO coupled with oxygen from a Praxair Vacuum Pressure Saving Adsorption (VPSA) plant can enable mills to reduce capital costs by one-half and power costs by one-third over air-based activated sludge systems.
