Method of using high molecular weight water soluble polymers in membrane bioreactor systems |
摘要 |
An activated sludge process for the clarification of wastewater comprising introducing the wastewater into a reactor where microorganisms consume organic material in the wastewater to form a mixed liquor comprising water, the microorganisms and an activated sludge; separating clarified water from the mixed liquor by filtration through a microfiltration or ultrafiltration membrane; separating the activated sludge from the mixed liquor; adding to the activated sludge at least one high molecular weight water soluble polymer to form a mixture of water and coagulated and flocculated solids; dewatering the coagulated and flocculated solids to form a mixture of dewatered solids and filtrate water; and recycling the filtrate water into the mixed liquor and a method of controlling polymer dosage, preferably using fluorescence emission spectroscopy.
