Screens for overflow structures

Reduce contamination from overflow structures with self-cleaning screens from Stjernholm

Stjernholm manufactures and markets 2 different types of screen for installation in overflow structures: the patented, hydraulically powered, vertical screen type VR and the engine-powered screen type RO. Both screen types are designed for optimal collection of screen material which is then led through the purification plant through the correct route.

The local conditions determine the optimal type of screen to use – including construction of the overflow structure and medium characteristics.

The VR screen is cleaned hydraulically and consists of a number of horizontal, parallel screen bars of which every second one is moveable. It is available with screen spacing of 4.5 and 10 mm which, during normal operation, ensures a collection of 90% of the screen material.

The RO screen is cleaned by means of an auger with brushes. Here, the screen material is collected by a perforated sheet. It is available in 3 different sizes and with a capacity of up to 1,200 litres per second.

Both screens are delivered with a complete control cabinet and they can be adjusted to perform time-determined operations or be regulated by level sensors that measure the water line level.
