WHEN TO USE IT

The GMB type basket screen is suitable for the screening of wastewater of civil and/or industrial origin, and specially it was designed to be installed on the inlet pipe of pumping systems.

HOW IT IS MADE

The main parts of the GMB-type screen are a mobile basket mounted on vertical guides, a stop log that closes the water flow when the basket is being emptied, a trellis that supports a hoist suitable for the downstream and upstream movements of the basket controlled by a pushbutton.

HOW IT WORKS

In the standard version, the GMB screen basket is installed on the inlet pipe in a pumping station. The water to be screened enters directly into the basket and the solids with a diameter equal to or larger than the predetermined filtration opening are retained inside. When solids fill the basket screen, a sensor alerts the operator. The operator, by means of an electric push-button panel, allows the basket to be lifted, while at the same time a stop log is lowered closing the inlet pipe in order to prevent the non-screened sewage from flowing into the lifting station. When the basket screen reaches and exceeds the ground level, following the guides of the trellis, it begins tilting to discharge into a waste bin. After discharging, the operator, by means of a push-button panel, returns the screen to its working position in front of the inlet pipe and the stop log automatically lifts allowing the inlet of the sewage.
