This is a literature review for the year 2015 and contains information specifically associated with suspended growth processes including activated sludge, upflow anaerobic sludge blanket, and sequencing batch reactors. The review encompasses modeling and kinetics, nutrient removal, system design and operation. Compared to past reviews, many topics show increase in activity in 2015. These includ...

A thermophilic mixed population of bacteria, capable of utilizing methanol as its sole carbon-energy source at temperatures up to 65 C, was selected by enrichment and studied. A maximal cellular yield of 0.42 g per g of methanol was observed at 50 to 56 C. The maximal specific growth rate of the mixed population in continuous culture at 56 C was greater than 0.32 per h. The amino acid profile o...

Advocates of waste minimization seek to encourage this form of industrial waste management through economic incentives. A review of waste reduction activities between the midnineteenth century and 1970 demonstrates that the influences of pollution control legislation, technological innovation, and cost savings produced only limited achievements when enforced or promoted separately. when governm...

Proper management of residues originated from industrial activities is considered as one of the serious challenges faced by industrial societies due to their potential hazards to the environment. Common disposal methods for industrial solid wastes (ISWs) encompass various combinations of solely management options, i.e. recycling, incineration, composting, and sanitary landfilling. Indeed, the p...

the main problem of solid waste management system in tehran is to handle a large amount of waste (7.641 ton/day in 2008). therefore, source reduction can be introduced as one of the first priority for solid waste management in tehran. this research represents the first attempt to quantify the source reduction potential in the city, and subsequently, outlines the principle guidelines, legislatio...

As the generation of industrial wastes increases, waste treatment is steadily becoming a serious economic and environmental issue. Existing waste has mainly been treated by landfilling after incineration. A shortage of landfill sites necessitates waste management alternatives other than traditional incineration and landfill. This paper focuses on a cost-benefit analysis that evaluates the econo...
