Solid waste management is the process of collecting, treating, and disposing of solid waste. This process includes: Collection, Transportation, Treatment, Analysis, Disposal.
In waste stabilization ponds, aerobic and anaerobic organisms work together to reduce BOD by up to 75%. Anaerobic and facultative ponds are designed to remove BOD, while aerobic ponds are designed to remove pathogens. Aerobic treatment is generally used for wastewater streams with lower BOD or a lower concentration of contaminants. Anaerobic treatment is used for streams with a higher concentration of impurities and for warm wastewater streams. Anaerobic treatment is used for initial reduction of organic contaminant levels, while aerobic treatment is used as a secondary polishing step. In an anaerobic-aerobic system, the stabilized sludge production will be smaller because of the comparably smaller sludge production in the anaerobic system.
Topics include: Oxidation and Stabilization Ponds, Construction of Septic Tank, Construction of Imhoff Tank, & Municipal Solid Waste.
