Sludge Pressure Filtration with Fly Ash Addition

for sludge conditioning. Fly ash can be ob tained from on-site coal-burning power plants at many industrial sites because it is an abundant waste product. Sludge ash recycle may be advantageous where sludge will be incinerated. Smith 1 investigated the effect of sludge ash from various sources and compared sludge ash with fly ash for laboratory vacuum filter dewatering of biological sludges. Sludge

Pressure Filtration of Waste Water Sludge with Ash

Optimum fly ash to sludge ratio for dewatering performance lies between 0.9 and 1.4. However, the optimum economic fly ash to sludge ratio may be different due to costs of trucking and materials handling of ash and chemicals, and other operating costs. 2. The value of ferric sulfate is not clear-cut.

FLY ASH EMPLOYMENT IN CONDITIONING

1988-1-1  The present paper deals with the fly ash utilization as a sludge conditioner prior to dewatering in a wastewater treatment plant. The term fly ash describes the particulate residue resulting from the combustion of coal. The fly ash evaluated in this study is a by-product of thermal power plants in Greece.

A study of the improvement in dewatering behavior of ...

2010-4-29  Pilot-scale filter-press dewatering equipment was used to deter-mine the dewaterability of wastewater sludge as a result of addingfly ash or polymer does. Fly ash dose was 30% and 50% respec-tively, and polymer dose was 20 ppm in the case of sludge with 50%fly ash. The dewaterability of wastewater sludge was initially testedwithout adding the fly ash. The process was then repeated after add-ing 30% fly ash to the total amount of sludge with a water contentof 97%. Further experiments were carried out using 50% fly ash,and 50% fly ash

Experimental Study on Fly Ash for Conditioning of

2013-12-24  When the sludge of sludge water of waterworks carries on the treatment of dewatering and drying, it is better to choose fly ash as conditioners (filter aid). In the process design of treat- ment of sludge water of waterworks, we need not set up the coagulation process, and only set up an intermediate regulating pond. It is easy to dewater for the sludge of waterworks that have been conditioning by fly ash,

SELECTING THE BEST DEWATERING TECHNOLOGY FOR A

2018-4-4  Similar to the filter press, the sludge feed pump applies pressure to the sludge; however, at a much lower pressure (2-7 psi). A restricted outlet at the end of the channel applies back pressure to the sludge with a pneumatic piston. The force on the restricted outlet controls the dryness of the cake. As the channel rotates, sludge is forced towards the outlet by way of friction from the sides of the channel
