Biological system analysis for domestic wastewater treatment in Colombia
Keywords:
Domestic wastewater, Wastewater treatment systems, Biological systems, EfficiencyAbstract
Some developing countries do not have efficient wastewater treatment systems, due to economic issues or limited knowledge of low-cost alternatives. This paper reviews and analyzes different domestic wastewater treatment systems in Colombia. The analysis shows that the most common treatments are activated sludge, stabilization ponds, and artificial wetlands, achieving 80% removal of Biochemical Oxygen Demand, Chemical Oxygen Demand, and Suspended Solids. When used together, they reach efficiency levels above 90%, highlighting the economic viability of these biological processes.
