Brazil, like many emerging countries, has experienced a fast growth in the demand for automobiles in recent decades. This has produced a significant increase in the amount of hazardous waste to be disposed of, including used lubricant oil. Restrictive regulations are being used by many nations to deal with this problem, focusing on treatments, such as recycling, to avoid resource depletion. Spe...

Industrial wastes may produce leachates that can contaminate the aquatic ecosystem. Toxicity testing in acute and chronic levels is essential to assess environmental risks from the soluble fractions of these wastes, since only chemical analysis may not be adequate to classify the hazard of an industrial waste. In this study, ten samples of solid wastes from textile, metal-mechanic, and pulp and...

Abstract Alum sludge (AS) is produced in inevitable amounts from drinking water treatment plants. Also, dye-contaminating wastewater usually discharged textile industries that must be treated to meet the environmental authorities; thus, Fenton’s reagent a suitable candidate. However, reducing quantity of chemicals used Fenton reactions can partly achieved by an industrial ecology approach. This...

with regard to environmental issues, proper operation of wastewater treatment plants is of particular importance that in the case of inappropriate utilization, they will cause serious problems. in order to achieve a better and efficient control over the operation of an industrial wastewater treatment plant (wwtp), powerful mathematical tool can be used that is based on recorded data from some b...
