Industrial wastes treating

The principal interest in photosynthetic bacteria for thek appHcabiUty to SCP production (Table 1) has been in Japan, where Jiodobacter capsulatus has been used to treat industrial wastes in sewage ponds (40,41). The product has been evaluated as a protein supplement in laying hen rations for egg production with acceptable results (40). 

Landfarming Landfarming is a waste-disposal method in which the biological, chemical, and physical processes that occur in the surface of the soil are used to treat biodegradable industrial wastes. Wastes to be treated are either apphed on top of the laud which has...

Bioventing technology was developed by the U.S. EPA Risk Reduction Engineering Laboratory to treat soil contaminated by numerous industrial wastes, which is subjected to aerobic microbial degradation, especially to promote the degradation of polycyclic aromatic hydrocarbons.65 It uses a series of air injection probes, each of which is attached to a low-pressure air pump. The air pump operates at extremely low pressures to allow the inflow of oxygen without volatilization of contaminants. Additional additives such as ozone or nutrients may also be supplied to stimulate microbial growth.77...

Cycom A combustion process for treating solid industrial wastes. The solids are fed into the top of a vertical gas-fired cylinder. The ash melts and flows down the walls for recovery. Developed by IGT, Chicago, and piloted with several industrial wastes in the 1990s. 

LARAN [Linde anaerobic methane] An anaerobic process for treating industrial waste waters, generating methane for use as fuel. The process uses a fixed-bed loop reactor. Developed by Linde in the early 1980s, first commercialized in 1987. 

NEUTREC A flue-gas desulfurization process, intended for treating the waste gases from incinerators for municipal, hospital, and industrial wastes. Sodium bicarbonate, optionally mixed with active carbon, is injected into the gases after the usual bag filter, and the solid products are removed in a second bag filter. Sodium compounds can be recovered from the product for reuse, and ary toxic compounds disposed of separately. Developed by Solvay and operated in Europe since 1991. 

All of the process streams that could be treated offsite have compositions similar to waste streams routinely treated by commercial industrial waste treatment facilities. Thus, they could be transported by standard commercial conveyance to commercial facilities that are appropriately permitted to receive the waste. 

Ozone produced by electrical discharge is used to purify drinking water and to treat industrial wastes and sewage. It is also use to deodorize air and kill bacteria by passing dry air through special ozone-producing electronic devices. 

In the field of bioremediation, oxidoreductases are considered to be excellent biocatalysts for environmentally friendly processes. Laccases and peroxidases are widely used to treat effluents from pulp/cotton mills, food/fruit processing plants and breweries [1, 2, 37]. Laccases, peroxidases and other oxygenases are also being studied for their abihty to degrade hazardous coal substances, especially the sulfur-containing components, and in the treatment of industrial waste and contaminated soil and water in the transformation of xenobiotics, polycycHc aromatic hydrocarbons and other pollutants (biodetoxification and biodecontamination)...
