Description
Noggerath® Vertical Sieve Screen NSI-V is a unique and adaptable solution for wastewater management, from the manhole to the final discharge point.
This compact unit, made of the highest quality stainless steel, combines a sieve, screw and press to provide an optimal wastewater screening experience and offers the following advantages:
- Compact, space-saving design. Vertical mounting and modular assembly make it easy to adapt the unit to different locations and conditions or to integrate into existing installations. This not only saves space but also saves money on infrastructure installation.
- Spiral brush efficiency. The spiral brush, mounted in the opposite direction to the conveying direction, prevents the material to be screened from passing through the screen. And the segmented design of the brush ensures quick and easy replacement of the brush elements and saves money by only replacing worn parts.
- Efficiency and energy savings. The unit performs fine screening, washing, conveying, compacting and dewatering in a single process, saving resources and space. And the direct drive with low energy consumption ensures efficient operation and contributes to energy savings.
- Easy maintenance. All the main parts of the vertical screen are bolted together, ensuring convenient and easy maintenance. This reduces the time and effort required for regular maintenance.
- Waste reduction. The unique compaction zone allows waste reduction of up to 60% and drying of up to 35% of the dry material, depending on the type of solid material. This reduces the amount of waste and the impact on the environment.
The Noggerath® Vertical Sieve Screen NSI-V is the solution that gives you the tools to overcome today’s wastewater management challenges.
How it works
The wastewater from the channel flows directly into the inner surface of the grate basket, where an efficient screening process begins. In this initial stage, solid particles gradually cover the surface of the basket and create a barrier to the free flow of liquid passing through the screen, resulting in a gradual increase in the liquid level. An upstream level measuring device monitors the liquid level. When this level reaches or exceeds a set maximum level, the conveyor drive is automatically activated. A spiral brush mounted on the screw, mounted in the opposite direction to the conveying direction, effectively cleans the surface of the bag. This brush not only prevents blockage of the openings but also lifts the solids onto the screw conveyor. The retained materials, which are transported by the rotating screw to the removal unit, are drained and compacted in the compaction zone. Once the screened material is lifted by the auger, the sieve is loosened and the liquid can start flowing again. When the liquid level drops below the set level, the screw conveyor automatically switches off and the unit is ready for a new cycle. This efficient process ensures continuous, uninterrupted wastewater treatment.
