Liquid sludge

Sludge Disposal. Land disposal of wet sludges can be accomplished ia a number of ways Lagooniag or the application of liquid sludge to land by tmck or spray system, or by pipeline to a remote agricultural or lagoon site. 

Several units are used for sulfite-paper-mill waste-liquor disposal. At least six units are used for oil-refinery wastes, whicdi sometimes include a mixture of liquid sludges, emulsions, and caustic waste... 

Your process may produce wastes that cannot be treated on-site, and so must be transported off-site for treatment and disposal. Wastes of this type are usually non-aqueous liquids, sludge, or solids. Often, wastes for off-site disposal are costly to transport and to treat, and represent a third-party liability. Therefore, minimization of these wastes yields a direct cost benefit, both present and future. Measure the quantity and note the composition of any wastes associated with your process that need to be sent for off-site disposal. Record your results in a table or an appropriate spreadsheet.

Dike An embankment or ridge, natural or man made, used to control the movement of liquids, sludges, solids or other materials. An overflow dike would be constructed in a fashion to allow the uncontaminated water to flow unobstructed over the dike keeping the contaminant behind the dike. An underflow dike allows the uncontaminated water to flow unobstructed under the dike keeping the contaminant behind the dike. 

An important route of plant contamination comes from direct contact during surface application of sludge. A study by Chaney and Lloyd [42] showed that sludge constituted 30% of forage dry matter immediately following spray application of liquid sludge on tall fescue (Festuca arundinacea Schreb). The sludge concentration decreased to 10% after 30 days. 

Second, the most important potential sources of nuisance in the disposal of sludges to land are the transfer of liquid sludge to a tanker, and the act of spreading itself. This is especially so with anaerobically digested sludges. 

Thermal distillation can be used to treat almost any type of hazardous organic waste, whether it is continuously generated or has been impounded for several years. It can be used to treat liquids, sludges, sediments, or soils. Units can be designed for fixed sites or for mobility. 

The Extra Pure process uses an unspecified solvent to extract organic contaminants from various wastes. The organics are separated from the solvent by distillation. The technology can be used for liquids, sludges, solids, or any mixture with a wide range of organics. 

Pumping liquid sludge, over a period of several months or more, into the lagoon. The pumped sludge is normally stabilized prior to apphcation. The sludge is usually applied until a lagoon depth of 24-48 in. (0.7-1.4 m) is achieved. 

Analyze the performance of a 60.5-ft diameter (max. surface area on top) evaporation lagoon in Spokane County, Washington, USA, for treating 5400-5580 gal per month of liquid sludge in April-June, assuming the following data are known ... 

Some of the drums were emptied into open pits and trenches, cleaned, and recycled. Other drums were buried on site and, during the later years of operation, many drums were stored on the surface. Mr. Taylor was eventually stopped from burning the chemical waste, and soil from nearby hillsides was used to cover the pits and trenches. Thousands of drums were also stored on the surface of the site, and investigation found four or five major cells of buried wastes containing chemical liquids, sludges, and crushed drums.
