The primary clarifier''s underflow and the waste activated sludge from the COP™ Clarifier are treated with polymer and then fed into a thickener to thicken the solids. The thickener effluent overflow is recycled back into the primary clarifier. The thickener''s underflow is again treated with polymer and sent to a filter press for dewatering.
According to this feature, we developed this drying equipment for drying papermaking sludge to be agricultural fertilizer. The dry sludge can be directly used as a soil improver. It can also be composted and processed into organic compound fertilizer. Working Principle Core Technology
May 17, 2018· Although new treatment technologies, and reuse and resource recovery strategies offer workable solutions, adding water reuse systems to paper mills can be challenging. Substances that can harm equipment and degrade product quality can build up in reused process water, so reuse systems must be customized for a specific mill and its product.
An integrated steel mill is composed of agglomeration, coking plant, blast furnace, steel mill, electric steel mill. ... liquid sludge treatment ; dewatered sludge treatment ; reagent storage and feeding ; ... the layout of large open recirculating systems used for gas scrubbing or for watering hot rolling mills, and how the blowdown is ...
Oct 15, 2004· Before 1980s, the treatment of pulp mill effluents by anaerobic means was limited, as most of the pulp mill effluents at that time were less concentrated (300–2000 mg/l BOD) (Bajpai, 2000) and were not suitable for anaerobic treatment. Anaerobic filter, upflow sludge blanket (UASB), fluidized bed, anaerobic lagoon, and anaerobic contact ...

Jul 10, 2019· The biofilm‐activated sludge (BAS) process was optimized by Revilla, Galán, and Viguri for the treatment of high COD nutrient limited wastewater and was implemented in a full‐scale wastewater treatment plant handling cellulose and viscose fiber mill effluents.
Anaerobic treatment is most commonly used for effluents originating from recycle paper mills, especially during production of containerboard. Moreover wastewater of mechanical pulping (peroxide bleached), semichemical pulping and sulphite and kraft evaporator condensates may be treated.
The largest secondary treatment systems today use the activated sludge process. Sixty to seventyfive per cent of all the biological effluent treatment plants within the pulp and paper industry ...

Codigestion, adaptation and/or pretreatment are key to mill sludge digestion. Abstract. Pulp and paper mills generate large amounts of waste organic matter that may be converted to renewable energy in form of methane. The anaerobic treatment of mill wastewater is widely accepted however, usually only applied to few selected streams ...
Disposal of sludge in incinerators or hog fuel boilers will cost between 11 and 13/dry ton. At the mill site sludge could be made available for other means of disposal at costs between 7 and 20/dry ton, depending on the
Foshan Huafeng Paper Co., Zaozhuang Huarun Paper Co., and Anhui Shanying Paper have lower capital and operating costs associated with the SBRs than if the recycle paper mills had selected a conventional activated sludge treatment process. The SBRs also have less processing equipment to maintain than other activated sludge systems.
Additional treatment may be needed before reuse. Sludge from wastewater treatment processes are treated and then disposed or reused in crop production or other applications. age per capita usage from public water supply systems in the United States was 184 .
