The basins frequently serve other purposes, make-up water ponds, recirulating ponds, receiving basins for slurry-pond waste, or emergency slurry ponds. Siltation basins constructed at the toe of refuse piles are also used to collect refuse leachate and runoff for sedimentation, and for subsequent treatment when necessary.

A slurry pit, also known as a farm slurry pit, slurry tank, slurry lagoon or slurry store, is a hole, dam, or circular concrete structure where farmers gather all their animal waste together with other unusable organic matter, such as hay and water run off from washing down dairies, stables, and barns, in order to convert it over a lengthy period of time into fertilizer that can eventually be ...

Such ponds are susceptible to disastrous releases, such as the Buffalo Creek flood of 1972 or the Martin County coal slurry spill of 2000, which released over 250 million gallons of coal slurry. Coal slurry can contain hazardous chemicals such as arsenic and mercury and can kill aquatic wildlife, as was the case in the Martin County spill.

Both agitation before pumpout and manure solids handling pumps matched to either the slurry irrigation system or "honey wagon" transfer tank are critical to successful waste storage pond pumpout. See the figure below for a cross section of a waste storage pond. Note the upper pumpdown stake. Pumping should begin when water reaches this level.

Impoundment ponds are created as part of the mining process, using the solid rock left after coal extraction. Dams are constructed using the rock and soil, and are generally located at the head of a valley near the coal preparation plant.Some impoundment ponds contain billions of gallons of slurry.

System and methods for remediating a slurry pond are disclosed herein. A method includes distributing a material over a surface of the slurry pond, wherein the slurry pond includes residues from a plant operation. A method also includes placing a load on the material, wherein the load causes the material to sink below a level of a supernatant but to remain above a layer of sludge in the slurry ...

Sludge Definition: We divide the sludge into two categories; (a) the slurry, and (b) the weight-bearing sludge. We chose a submerged weight of 0.125 pounds per square inch (psi) as the dividing line between slurry and weight bearing sludge. If the sludge density is light and cannot support 0.125 psi, then we consider it slurry.

A slurry pipeline is used to transport slurries from the source such as a coal mine to its destination such as a coal power plant. In this case the coal slurry will be a mixture of coal and water, which is a transportation medium used to propel the combined solid-liquid mass through the pipeline using centrifugal pumps to provide the required ...
