Recycling of Pigment Baghouse Dust from Air Pollution Equipment

Some of the dusts generated during the handling, grinding, and mixing of pigments can be hazardous. Therefore, dust collection equipment such as hoods, exhaust fans, and baghouses are provided to minimize worker exposure, to localize dust and to filter ventilation air exhaust. Much of the pigment dust collected in baghouses can be reused to make low-grade paint. This effort can be aided by installing a dedicated baghouse system for the pigment loading area.

Process Description

Before a product coating can be applied to a surface, the surface must be free from contamination. As described elsewhere in this report, many different types of abrasives, alkalines, acids, and solvents, as well as water, are used by industry to clean metal surfaces. Once a part is cleaned, surface treatment such as phosphate coating can be applied if desired. The purpose of surface treatment is to condition or prepare the surface so that the paint forms a better bond with the metal surface....

Hazardous Slags

In the production of ductile iron, calcium carbide is often used as a desulfurizing agent. When added to the iron, it reacts with the sulfides and forms calcium sulfide. This material floats on the surface of the molten iron, where it is skimmed off the surface and placed in a hopper. Since excess carbide is employed to ensure removal of the sulfur, the resulting slag contains high levels of unreactive carbide and must be handled as a reactive waste. Treatment of this material normally consists...

S1J Metal Reclamation

Sands used in the production of brass and bronze castings often pick up lead contamination and must be disposed of as hazardous waste. It has been reported (HazTECH News 1988) that Pittsburgh Mineral and Environmental Technology, Inc. has developed a process that can recover more than 90 percent of the metal value from the sand and render the sand nonhazardous. Table 5-1 summarizes the waste reduction methods discussed in this chapter, and references concerning them. For more useful information...

Recovery Of Elemental Mercury

An important engineering consideration in the design and operation of the biological process for mercury removal is the fate of the reduced mercury during treatment. A significant portion of the mercury that is reduced in the biological process will exit the bioreactor as a vapor along with other effluent gases (mainly N2. 02 and CO2). When air is used as the oxygen source for the biological process, the partial pressure of the elemental mercury vapor in the effluent gas stream is very low....

Wastewater Effluent Requirements

The primary waste management concern of many metal fabricators appears to be meeting wastewater effluent requirements for discharges to the local POTWs. Limitations on the chemical concentrations that can be discharged to sanitary sewers have increased the demands on the plant's industrial waste treatment system. In addition, the potential fines and other penalties associated with violating these discharge requirements have become more severe in the last few years. As a result, metal...

Recycle Electric Arc Furnace Dust

Electric arc furnaces (EAFs) generally convert 1 to 2 of the charge into dust or fume (Chaubal 1982). Zinc contents of the dust have potentially high commercial value. Many methods have been proposed for flue-dust recycling, including zinc recovery. A good survey of recycling strategies is given by Morris (1985). Most recovery options require the zinc content of the dust to be at least 15 , and preferably 20 for the operation to be economical. Increasing zinc content can be accomplished by...

Aqueousbased Cleaning

Historically, aqueous solutions have been used extensively throughout the industry. In recent years, their use has increased as environmental concerns and regulatory restrictions placed solvent cleaners under more scrutiny. Aqueous cleaning comprises a wide range of water-based cleaning methods that use detergents, acids, and alkaline compounds to displace soil rather than dissolving it in organic solvent. Aqueous cleaning has been found to be a viable substitute for solvents in many parts...

Regulations continue to become more stringent as to where and how long this waste is stored, as veil as the methods of storage and disposal. Disposal costs continue to increase. Is there a solution to this problem The FINAL TREATMENT Distillation Unit uses a new method to concentrate the cyanide ions in order to minimize the volume of the...

Many electronic companies in the State of California create a substantial volume of arsenic waste through the processing or manufacture of gallium arsenide (GaAs) microchips. Since the concentration of arsenic in wastewaters or sludges usually exceeds disposal limits for sewer and municipal landfills, these wastes are quite often treated and disposed to a Class I hazardous landfill. This practice is undesirable environmentally and economically as a long-term mechanism for waste disposal. The...

Foundry Charge Modification Ep Toxicity Test Results

The metallurgy problems will determine the feasibility of such an alternative. In general, this method for hazardous waste minimization is generally not used by a majority of foundries. Another reuse alternative outside of the original process is to reclaim the lead and cadmium which have concentrated in the emission control residuals. The feasibility of this reclamation outside of the original production process largely depends on the concentration of metals within the residual, the cost of...

Baghouse Dusts

One way to eliminate the generation of hazardous baghouse dusts is to use pigments in paste form instead of dry powders. Pigments in paste form are dry pigments that have been wetted or mixed with resins. Since these pigments are wet, less or no dust is generated when the package is opened. In addition, most pigments in paste form are supplied in 'Confidential source 1985 Personal communication. ZE.I.

During the past 50 years, thermal spray technology has gained widespread attention as a means of providing machinery parts with wear and corrosion-resistant coatings. These coating are used not only for enhancing the mechanical properties of the base material, but are very useful in salvaging worn machine elements, the latter being the most dominant in thermal spray service repair shops. To date we have a number of thermal spray processes which we can use to improve a part's surface...

Process Chemical Removal

Adequate drainage and efficient rinsing of workpieces is necessary in order to keep hazardous metal solutions within the process, rather than escaping in the effluent. Increasing drainage time of flat, vertical parts from one to six seconds reduces drag-out by half. How the parts are racked also has an effect on drag-out, as do the viscosity and temperature of the process bath. The addition of one closed loop rinse can significantly reduce the amount of metal in the effluent. Agitating the...

Electronic parts makers, platers and other metal finishers require clean water rinses to remove plating chemicals from parts prior to the next process. The rinse water is sometimes expensive or in short supply. Furthermore, if the water is of poor quality, it must be pre-treated prior to use. The water is discarded after one use with conventional waste treatment, precipitation and clarification and a hazardous mixed metal sludge is generated which must be shipped to a hazardous waste landfill....
