SCREENS:
EFFECTIVE. HIGH VALUED. INDIVIDUAL.

Screens, also known as bar grates, retain harmful or disturbing substances in water and waste water plants. Pumps in pumping stations and service water extraction stations are thus protected from damage and wastewater channels or sewage treatment plants are kept free of bulky substances. In hydroelectric power plants, screens enable turbines to operate smoothly or prevent the further transport of organic flotsam and civilisation waste in flowing waters.

The screens are mainly made of commercially available flat steel. Special profiles are available for special cases, e.g. to retain bulky flotsam, but to allow grass to pass through in a targeted manner. Suitable reinforcements in the required number ensure the desired gap width over the entire screen surface.

In most cases, hot-dip galvanizing of the screens made of mild steel is sufficient as corrosion protection. In case of extreme loads caused by salts or chemical substances, we use stainless steels or other highly corrosion-resistant material (qualities according to requirements).

 

USUAL GAP WIDTHS

Pumping units 40 – 100 mm
Waste water facilities 20 – 50 mm
Barrages 50 – 150 mm
Hydroelectric power plants 20 – 70 mm
Domestic water withdrawals 20 – 40 mm

For both manual and mechanical cleaning, a 15° inclination of the screens has proven to be the best solution. If special operating conditions are to be expected (increased ice flow, release of the channel as emergency overflow), lifting or folding screens are provided instead of the fixed screens.
