Noggerath Spiral Sieves NSI

Product catalog summary

Overview
The document provides detailed information on the Noggerath Spiral Sieves NSI, a product of Passavant-Geiger GmbH, used in screening technology for wastewater treatment. It outlines the specifications, applications, and advantages of different models of the NSI series.

Specifications
The NSI series includes models NSI 200, NSI 300, NSI 400, and NSI 500, with sieve basket diameters ranging from 200 mm to 500 mm. The installation angle can be 35° or 45°, with the latter requiring a spray bar and solenoid valve. The channel width is the minimum diameter of the sieve basket plus 100 mm, and the length is variable in 100 mm steps.

Models and Technical Data

NSI-B Series: Includes models NSI-B 200/S, NSI-B 300/S, and NSI-B 500/S, with discharge heights from 700 mm to 1500 mm, total lengths from 1800 mm to 3150 mm, and drive power ranging from 0.37 kW to 0.75 kW. Flow capacity varies from 10 l/s to 80-120 l/s depending on the medium/application.
NSI-FA Series: The NSI-FA 500/S model has a discharge height of 1500 mm, a total length of 3205 mm, and a drive power of 1.00 kW. It has a throughput capacity of 100 m3/h, depending on the solids content.

Applications
The NSI series is suitable for municipal and industrial wastewater treatment, pre-sieving in potable water treatment plants, and sludge and septic sludge screening. The NSI-FA model is specifically designed for handling faecal sludges.

Advantages

Fine screening, transport, pressing, dewatering, and discharge of solids in one machine.
Easy retrofitting and integration into existing plants without bed drop.
Complete hygienic stainless steel encapsulation and no clogging due to shaftless spiral.
No service water required in the compaction zone or at a 35° installation angle.
Outdoor and indoor installation capabilities.

Functionality
The liquid enters the sieve basket, retaining solids larger than the sieve surface aperture. As solids accumulate, the upstream liquid level rises, triggering the spiral drive. Solids are transported to the pressing zone for dewatering, and a rotating scraper discharges the dewatered solids. A spiral brush cleans the sieve surface, and the drive stops when the liquid level drops.

Conclusion
The Noggerath Spiral Sieves NSI series offers a comprehensive solution for fine screening in wastewater treatment, with various models tailored to specific applications and operational needs.
