Air Scouring is a proven method of efficiently removing bio-films, sediment and other debris from the internal bore of reticulated water mains. The method employs the injection of filtered compressed air into the water mains to form 'slugs'. The air/water combination along with an increase in the flow velocity removes the solids, sludge, particulates and other foreign matter from the internal walls of the pipeline.
HORIZON Industrial provides Air Scouring Services as an effective means of ensuring the delivery of high quality drinking water whilst extending the life of the reticulation system and, maintaining optimum operating levels.
