Whilst Coanda screens are typically very low maintenance, for a small number of installations, certain conditions can result in increased cleaning requirements. Depending on the location of the Coanda screen and factors such the flow conditions and the biological component of the water, stubborn debris such as algae and moss can build up slowly over time, creating blockages and reducing abstraction, limiting the effectiveness of the screen and resulting in production losses.
Where this happens, adopting a more frequent cleaning regime is recommended. But in locations where access is difficult or complicated by weather conditions or geography, then an automated solution could be considered. In particular, to avoid sole operators working in the water in high flow conditions, or accessing the site during adverse weather. The automatic screen cleaner can offer a useful enhancement to any Health and Safety Management System.
