Abstract

Wastewater from car washers and lubricators contain high levels of hydrocarbons. These are discharged into the public sewer system without proper treatment and not complying with the regulations. In this study was evaluated the process of bioremediation of total hydrocarbons in Puyango’s [...]

Abstract

A pilot aerobic horizontal plug flow reactor filled with pieces of PET (polyethylene terephthalate), from plastic bottles was installed for treatment of a synthetic substrate prepared from lactic whey with COD values of 800 to 2100 mg/L. A bacterial inoculum previously acclimated [...]

Abstract

The 100-F-26:15 waste site consisted of the remnant portions of underground process effluent and floor drain pipelines that originated at the 105-F Reactor. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed [...]

Abstract

The 100-F-26:8 waste site consisted of the underground pipelines that conveyed sanitary waste water from the 1701-F Gatehouse, 1709-F Fire Station, and the 1720-F Administrative Office to the 1607-F1 septic tank. The site has been remediated and presently exists as an open excavation. [...]

Abstract

Several experiments have been conducted in order to improve the understanding of the wastewater drag and the wall frictional force acting on the headspace air in gravity sewers. The aim of the study is to improve the data basis for a numerical model of natural sewer ventilation. The [...]

Abstract

Every year millions of cubic meters of wastewater are discharged into water bodies, which are treated in an inadequate way, these procedures being inefficient to achieve what is required by law or for use within industrial processes. In these cases, and due to the scarcity of water, [...]
