However, since the naphthalene produced from petroleum is of high purity and quaUty, the production of refined naphthalene by such chemical treatments essentially has ceased in the United States. Not only are such treatments expensive, but they also generate a significant amount of waste sludge, which creates additional costs for appropriate waste-disposal faciUties.

Listing of solid wastes, quantities, analyses and physical form (e.g. solid, slurry, suspension, sludge) toxicity and flammability. Checking the reliability and legality of waste disposal options, including any transportation offsite. Record keeping. 

For PM applications, wet scrubbers generate waste in the form of a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water. The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. 

In wet FGD systems, fine gas exiting from the particulate collector flows to an absorber. In the absorber, the flue gas comes into contact with the sorbent slurry. The innovative scrubbers in the CCT program featured a variety of technologies to maximize SO, absorption and to minimize the waste disposal problems (sludge). 

Disposal of industrial effluents to controlled landfill sites is generally confined to slurries and sludge. The quantity and composition of the wastes acceptable for disposal is controlled by licenses issued by the waste disposal authority. 

The rising cost of scrap and waste disposal, the scarcity of onsite landfill space, and potential environmental liabilities make it an economic necessity to recover iron units from dust and sludge. However, recycling to the blast furnace raises the hot metal phosphorus content to undesirable levels. 

Extraction of pollutants from air emissions using CAA controls (e.g., scrubbers) can create hazardous wastes or sludges containing such wastes. Disposal of these materials must comply with RCRA. 

Table 1 indicates primary pollutant sources and waste modes, and Table 2 indicates the primary and secondary sources and associated pollutants. The primary sources of soil contamination include land disposal of solid waste sludge and waste-water industrial activities and leakages and spills, primarily of petroleum products. The solid waste disposal sites include dumps, landfills, sanitary landfills, and secured landfills.

Other disposal options for the sewage sludge are landfill, dumping at sea (forbidden in the EU since 1998) [30], and incineration. The most popular for solid waste disposal is landfill. However, many of the disposal sites are open dumps without protective barriers or leachate-collection systems, which represent a potential risk to the quality of the nearby groundwater. 

Release routes of 3,3 -dichlorobenzidine to the environment appear to be waste waters, sludges, and solid wastes where emissions are not properly controlled during the use of 3,3 -dichlorobenzidine or during its chemical transformation to pigments. The compound has been found in water and soil at hazardous waste sites, a result of the improper land disposal of solid wastes. 

The apparent solnbility of contaminants can be defined when the theoretical solubility deviates from the initial valne, as a result of a number of factors encountered in the snbsnrface environment. Waste and sludge disposal sites usually contain a...
