Performance of an Upflow anaerobic sludge blanket reactor for hospitals’ wastewaters treatment in Colombia: A preliminary study.
Resumen
The hospitals’ wastewater is considered harmful to the environment and public health, which demands the utilization of proper treatment systems to manage the pollutants in them. This study evaluated the performance of an anaerobic reactor Upflow Sludge Blanket (UASB) to treat real hospitals’ wastewater (HWW). The reactor operated for 145 days with variations of the amount of organic load rate (OLR). The results showed that for mean organic load rate (OLR) of 0.950 Kg COD / m3.d the removal efficiency of organic matter was 59 ± 14%, however, the process was unstable and showed low methane gas production. As a result, this research found that UASB standard systems are not reliable and proper treatment technologies y for treating organic pollutants of hospitals’ wastewater.
