Abstract
The present disclosure relates to the hydrostatic testing of pipelines and to purification of waste water from such testing. More specifically, there is provided a method of hydrostatically pressure testing a natural gas pipeline using water. The waste water, which is contaminated with hydrocarbons, is subsequently treated by contacting it with manganese dioxide so that the hydrocarbons are broken down into carbon dioxide and water.
