Insights

Since 1988, Noggerath® wastewater fine screening has been part of the standard equipment of inlet constructions. Robustness in design, versatility in use and efficiency in operation contribute to the fact that Noggerath® Spiral Sieve NSI can be found all over the world.
The design: The liquid flows into the sieve basket, which is open on the inlet side. Solids are retained here. A level gauge installed upstream of the spiral sieve registers the respective liquid level and switches the spiral sieve drive on or off automatically when a preset level is reached/underrun. The solids deposited in the sieve basket are conveyed by the spiral to the discharge; in the Version NSI and NSI-RED, the materials are additionally dewatered and compacted in the pressing zone.

In the RED version, the drive of the conveying system is designed as a drive unit with axially free discharge. This drive concept allows a discharge area without drive elements and thus solves the central problem of the formation of screenings and blockages in the discharge area.
