Description

The Noggerath® wash press NWP is a simple, versatile and easily adaptable washing press

The Noggerath® wash press NWP is a reliable 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, washing, 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 local conditions.
  • Re-use of organic material. Leached organic matter can be recycled back into the downstream process to maintain denitrification and improve environmental protection.
  • 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® wash press NWP can be equipped with 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 Noggerath® wash press NWP has a simple and consistent operating principle. The materials are caught by a screw in the feeding zone and pushed into the washing/compression zone. The feeding zone includes the transfer, pressing and drainage zones, where a slotted drainage bed allows static drainage of the media. In the washing zone, organic matter is separated from the separated material, decomposed and washed away. The soil is further pushed by a screw into the compaction zone, where it is drained and compacted by gravity. In the compaction zone, the tailings are compacted to a specified rate and pushed through a friction pipe to a removal unit or packaged.
