    AREA OF USE

    Our step screen is a self cleaning fine screen for water treatment with very high separation degree of solids. A great deal of development work has been carried out to improve the separation at the bottom of the screen, a weak spot in other fine screens on the market.

    We guarantee the slot width along the entire screening surface and can be operated with almost fully covering screenings mat. Slot widths 1-6 mm.

    The unique patented design gives our step screen several advantages, especially below the water surface and at the bottom of the

    Our screen has a motion which retains the prescribed slot width during the entire working cycle. Due to the progressive motion only a small part of the screenings mat is transported up during each cycle. This minimizes the “rush” of water through the screen that can occur after a traditional screening cycle.

    The risk for blockage of sand or grain is eliminated by the design where the movingparts never open a wider space than the actual slot width. The step can be operated with very short pulses and doesn’t have to make a complete working cycle to the home position. Due to this procedure the screenings mat can be kept fully covering, which results in a very high separation degree (up to 50% higher than other designs).

    Our step screen is the only screen on the market, ensure slot widths down to 1 mm for the entire screening surface.

    Our step screens work intermittently. 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.
