Fluidization test of paper mill sludge with moisture of 12 75% was conducted in a cold bubbling fluidized bed (BFB) model Particle size and weight fraction of silica sand mixed with sludge as dual-component bed materials for better fluidization are optimized
With the introduction of online solids measurement wastewater treatment operations are experiencing greater than 50% reduction in polymer cost The most common equipment used in municipal wastewater treatment plants for dewatering sludge is a Centrifuge Other technologies include the Fournier Rotary Press and various types of Screw Presses
Dec 10 2019At Stora Enso's Heinola fluting mill bio-sludge is a byproduct of wastewater treatment Previously the mill would burn the bio-sludge at the power station for thermal power but because it is so wet it needed fossil-based fuel to support the burning process

Closed mill operation and recycling the treated water for consumption within the mill reduces the environmental liability risk associated with wastewater discharge • Water savings Water recycling will reduce the overall water consumption in the mill thereby providing savings in the costs associated with fresh water and wastewater treatment
Drying sludge for optimal recovery The limits of mechanical sludge drying sometimes create the need for thermal drying by water evaporation SUEZ has developed a number of sludge drying processes that allow the sludge to be recovered for a multitude of uses as fertilisers co-products for composting or as fuel for incineration plants

Monroe Environmental builds Primary and Secondary Circular Clarifiers for industrial and municipal wastewater treatment as well as Flocculating Clarifiers and Solids Contact Clarifiers for clean water or potable water applications Our experienced staff will provide high efficiency low maintenance systems that will provide the highest return on investment
Bypassing a clarifier which means routing mill effluent directly to secondary treatment in an aeration basin is done only in emergencies when clarifier equipment must be repaired or the sludge removal system is not able to process the sludge volume it receives
The mill also required that the clarifier meet a stringent process guarantee for both effluent solids (15 mg/L TSS) and underflow sludge concentrations (5% solids by weight) Solution Monroe Environmental began by testing representative water samples to determine if its proposed system could meet the desired performance
In municipal waste water treatment plants (MWWTP) the K-S Paddle Sludge Dryer System produces Class A Biosolids in accordance with the EPA's 503 regulations allowing the dried granular material to be used beneficially as a slow release fertilizer or soil amendment Dried waste products have also been used as fuel in boilers and cement kilns
GN Oil Sludge Treatment equipment is to use chemical to wash the oil sludge with heat to temperature of 60-70 C degree After washing the sludge is pumped to GN solids control equipment to separate into oil water and solids The recycled water can be reused in the washing process and the oil is clean enough to sell to the refinery company
