Phenolic wastes

Corrective Action Application Fluidized bed incineration has been used to incinerate municipal wastewater treatment plant sludge, oil refinery waste, some pharmaceutical wastes, and some chemical wastes including phenolic waste, and methyl methacrylate. Heat recovery is piossible.

The vendor indicates the technology can treat waste streams containing solvents, petroleum distillates, chlorinated solvents, pesticides and herbicides, as well as phenolic wastes, pulping liquors, municipal sewage, and industrial sludges. 

The process is applicable to Ihe treatment of almost any type of organic waste waters which can serve as food for biological growth. It has been applied to cannery wastes, milk products wastes, corn products wastes, and even phenolic wastes. I11 the treatment of phenolic wastes a special flora is developed which thrives on phenol as food. 

Phenolic wastes are one of the most prevalent forms of chemical pollutants in industry today. The major sources of phenolic waste are insulation fiberglass manufacturing, petroleum refineries, textile mills, steel making, plywood, hardboard production, manufacture of organic chemicals, paint stripping, and wood preservatives. Eisenhauer (1964) first studied oxidation of phenolic wastes with Fenton s reagent. It has been demonstrated that the oxidation of phenol involves the intermediate formation of catechol and hydroquinone (Merz and Waters, 1949 Stein and Weiss, 1951 Wieland and...

Semiconductor photocatalysis has been successfully applied in degradation of pollutants e.g. S02 and phenolic waste [69], It is mainly Ti02, which have been used and studied for this purpose, but there are reports where hematite has been used for photodegradation [52-54, 56, 57, 110, 111]. Hematite has also been studied as a gas sensing material [40].

Vortex briefly and spin in a microfuge. Note the color change of the lower organic layer from orange to pink. Transfer the yellow aqueous upper layer to a fresh siliconized Eppendorf tube. Discard the lower layer to radioactive phenol waste. Monitor with a Geiger counter typically approx 0.1 mCi of the label is discarded in the waste. 

The significance of the reaction of phenol with hydrogen has a number of important facets. First, the selective hydrogenation of phenol yields cyclohexanone, which is a key raw material in the production of both caprolactam for nylon 6 and adipic acid for nylon 6 . Second, due to the fact that phenol is an environmental toxin and phenolic waste has a variety of origins from industrial sources including oil refineries, petrochemical units, polymeric resin manufacturing and plastic units , catalytic hydrogenation of phenol is nowadays the best practicable environmental option . ...

Waste Treatment In addition to the waste treatment applications mentioned earlier under ultrafiltration, there are more applications in the removal of organics and inorganics from synfuel wastes, phenolic wastes, organic acid wastes, and pesticides wastes (Siler Bhattacharyya, 1985). 

Phenolic wastes. Phenols are an example of a group of compounds which are toxic to microbes (as shown by the use of many as disinfectants) and may therefore be difficult to remove by biological effluent treatment or by natural processes in the aquatic environment. This is especially true of high or widely fluctuating levels of phenols. Hence, chemical methods are often required in these cases. 

Remove the aqueous (top) phase to a fresh tube. As it cools, it may become cloudy due to residual phenol. This phenol will be removed by ethanol washes. Dispose of phenol waste in the correct hazardous waste containers. 

Distillation is used in treating and recycling a variety of wastes, including solvents, waste oil, aqueous phenolic wastes, and mixtures of ethylbenzene and styrene. What is the major hazardous waste problem that arises from the use of distillation for waste treatment ...

In many cases the hazardous nature of the chemical is increased when the chemical is mixed with another type of chemical, especially when the chemicals are incompatible. To avoid this situation, chemical waste generated in the CEL will be segregated by type (e.g., add waste, caustic waste, mercury waste, cyanide waste, and phenol waste).
