Noggerath® Screenings Press NSP

Description

Noggerath® screening press NSP – simple and cost-effective processing of screened materials

The Noggerath® screenings press NSP is a robust unit designed to effectively meet the challenges of municipal and industrial wastewater treatment in combination with pre-treatment screens and grates. It includes transport, dewatering, compaction and safe disposal of the treated material. They are not only environmentally friendly, but also an economical and cost-saving way to handle sieved materials.

Benefits

Reduction of operating costs. Replacement wear profiles in the press area and a screw made of wear-resistant special steel reduce wear and operating costs.
Ease of maintenance. The modular design and good accessibility to all parts ensure that maintenance is easy and efficient.
Efficient drainage. Direct contact between the auger and the slotted bottom of the drainage area ensures efficient, clog-free drainage.
Best drainage performance. The adaptable drainage bottom and the extended feed zone allow the best possible drainage performance, adapting to the local conditions.
Flexibility and adaptability. Thanks to their modular design, these scrubbing presses are easily adaptable not only to new projects but can also be integrated into existing wastewater treatment plants.
Efficiency and sustainability. Up to 80% reduction in the weight of untreated waste and up to 45% reduction in the dry solids content of the sieved material ensure that the discharged materials meet high environmental standards.

The Noggerath® screenings press NSP has the following options

NWP/ NSP-FF- Standard design, feed and press zone bottom made of flat profile with elongated meshes for coarse and fine screening (>2 mm) with normal water content in the screening medium.
NWP/ NSP-PF- Inlet zone with perforated sieve bottom and pressing zone made of flat profile bottom with elongated meshes for fine screening (>2 mm ≤10 mm) and higher water content in the screening medium.
NWP/ NSP-PW – Feed zone with perforated screen bottom and press zone with wedge wire screen bottom for fine screening (<=2) with low water content in the screening medium.

How it works

The principle of operation of the Noggerath® screenings press NSP is consistent and simple. The materials are captured by a screw in the feeding zone and pushed into the compaction zone. The feeding zone includes the transfer, pressing and drainage zones, where a slotted drainage bed allows static drainage of the media. The material is further pushed by means of a screw into the compaction zone, where it is drained and compacted by gravity. In the compaction zone, the aggregate is compacted to a specified rate and pushed through a friction pipe to a removal unit or packed.
