CleanFlo™ Rotoscreen® Fine Screen


CleanFlo™ Rotoscreen® Fine Screen Overview:

CleanFlo™ Rotoscreen® is a self-cleaning fine screen for separation of solids from water. The screen has a very low flow resistance which results in a low head loss. This is an advantage at installations in open channels.

CleanFlo™ Rotoscreen® is manufactured in different models depending on the discharge height. All models are available in different widths to fit into channels of various sizes. The screens are fully-enclosed and equipped with a ventilation pipe.

CleanFlo™ Rotoscreen® works intermittent. This leads to an operation adjustable to the incoming flow. A level sensor is installed in the channel in front of the screen. The screen starts when a pre-set water level is reached and operates until the water level is below the pre-set value. The cycle is repeated when the level is reached again.

CleanFlo™ Rotoscreen® features optimized-cycle control to minimize wear and maximize screening efficiency. The operating cycle is regulated by wastewater level, allowing screenings to gather and form a fine-mesh precoat which is removed once wastewater backs up to trigger the next cycle.

Nordic Water and MEVA are now partners with WesTech for USA and Canada.
