Problems wastes

Group 2 includes long-term reduction measures involving process modifications or process substitutions to eliminate problem wastes. This second group of corrective actions fall into two investment categories - moderate and high. Such projects... 

In extreme situations, incompatibility between injection fluids and reservoir components can be so great that deep-well disposal will not be the most cost-effective approach to waste disposal. In other situations, such remedial measures as pretreatment or controlling fluid concentrations or temperatures can permit injection even when incompatibilities exist. In addition to operational problems, waste-reservoir incompatibility can cause wastes to migrate out of the injection zone (casing/confining-layer failure) and even cause surface-water contamination (well blowout). 

Removal and purification of waste waters, especially in densely populated and industrial areas, has become a serious problem. Waste waters are very different. They generally contain a complex mixture of solids and dissolved components of different... 

This problem wastes quite a bit of toner, but can be fixed easily. The solution (again) is to replace the toner cartridge with a known, good, manufacturer-recommended one. If that doesn t solve the problem, then the HVPS is at fault (it s not providing the high voltage that the charging corona needs to function). 

Every effluent treatment plant will produce solid waste, which has to be disposed off properly, as it contains hazardous chemicals. Some of these materials are highly toxic, others are corrosive, flammable, irritants, explosive, infectious etc. Disposal of these solid wastes always presents a problem. Waste disposal systems...

Another difficulty is that only a small part of problem waste contains cations or well sorbed matter. Reactor waste often contains radioactive isotopes in the form of anions, which in substance are not adsorbed. In waste waters of chemical factories is also present unabsorbable matter and also ligands, which may form with cations complex compounds strongly degrading cation adsorption. One more consequence of adsorption and retardation is that a water horizon contaminated with adsorbed matter is very difficult to clean up and remove pollutants from it. 

There are two reasons for a low degree of acceptance for energy recovery from waste, the first one is fear for environmental pollution, and the second one are the corrosion problems. Waste incineration plants are not operated with the aim of producing energy. The main purpose is, and remains, to reduce the volume of waste to a considerable degree by means of incineration. On the other hand, only inert waste is allowed to be land-filled. New technologies for waste incineration must accomplish all demands regarding pollution.
