Noggerath® Sewer Grit Receiving Station

Noggerath® Sewer Grit Receiving Station

Noggerath® Sewer Grit Receiving Stations – comprehensive solution for surface water network infrastructures.

The Noggerath® Sewer Grit Receiving Station is designed and developed to solve the major problem of treating the surface wastewater infrastructure of European cities. A problem faced by traditional tanker emptying methods:

  • Insufficient separation capacity.
  • Environmental problems.
  • Problems with the handling of different types of contaminants.

Bearing this in mind, the engineers at Aqseptence Group have crafted the Noggerath® Sewer Grit Receiving Station, revolutionizing our approach to surface wastewater treatment.

Description

Noggerath® Sewer Grit Receiving Station is designed to receive mixtures of organics, solids and water collected by specialised vehicles that wash surface water pipes and streets.

Many European cities are facing the major challenge of stormwater pollution. Sand, gravel, dirt, tree leaves and other debris are constantly being carried from the street into the surface water pipeline with rainwater and aftershocks. These debris accumulate over a long period of time, clogging the pipeline and disrupting the smooth functioning of the surface water system, increasing the risk of flooding. Many wastewater network operators are now forced to use specialised vehicles to wash pipes and vacuum up the accumulated debris. As surface water management involves cleaning of collection wells and pipelines, sand and oil traps, settling basins and soil disposal, traditional tanker emptying methods face several challenges:

  • Insufficient separation capability. With large volumes of contaminants, it is difficult for traditional methods to effectively separate different materials.
  • Environmental problems. Some of the materials that tankers dump into waste sites or concrete settling ponds can cause environmental pollution and odour problems.
  • Problems with the handling of different types of material. Solid materials can be left without proper treatment and dewatering, raising questions about their safe handling.

The  Aqseptence Group solution

Aware of these problems, engineers from the Aqseptence Group have designed and developed the Noggerath® Sewer Grit Receiving Station, which is revolutionising the way we approach the treatment of surface wastewater systems. This unique three-stage system allows:

  • With a protected receiving hopper to efficiently receive a mixture of gravel, sand, sludge, organics and water from tankers and the ability to provide the necessary security at this critical point.
  • Separating coarse materials: with Noggerath® drum screen RSH-I for separating solids from liquids and the possibility to adapt them to the different types of materials to be screened, the volumes to be screened and the working conditions. With Noggerath® SpiralConveyor SC for transporting separated coarse materials into the container.
  • Sand cleaning: With the Noggerath® grit washing unit GWC, designed to leach organic matter from sand and gravel and to not only reuse the leached sand but also to save on waste transport and storage costs.

Each Noggerath® sewer grit receiving station is tailored to the site-specific conditions, materials and volumes. This allows for an efficient and individual solution to the different challenges of surface water drainage systems in each different city.

How it works

The Noggerath® Sewer Sand Receiving Station is a unique and comprehensive solution that operates on a three-stage system.

  1. Emptying of tankers and acceptance of the mass of waste material.
  • The emptying of the tankers and the reception of the sewer sand and sludge waste takes place in a stainless steel bunker with various protection systems (anti-splash, anti-clogging, anti-overflow, anti-wear and anti-deformation).
  • The bunker and other facilities are located at a lower level to facilitate the emptying of tankers.
  • From the hopper, a rotating auger provides controlled transport of the bulk material to the drum grates.
  • Measuring and control devices with programming and an integrated emergency overflow from the hopper to the drum grate ensure the necessary operational safety.

      2. Separation and transport of coarse aggregates

  • From the hopper, the bulk solids are fed into the horizontal drum screen, which is the main part of the receiving station and where the separation of coarse solids takes place.
  • As the solids pass through the drum, they are washed and partially drained, reducing their weight and odour.
  • The separated bulk solids are lifted upwards by a screw conveyor for disposal in a container or bagging. On the way, they are further dewatered to remove water from the waste and to prevent the formation of sludge, which causes transport problems.

      3. Washing of sand and separation of organic matter.

  • The mixture of sand and waste water is transported by pump from the hopper under the drum grate to the sand washing unit located on the working platform above.
  • Here, the wash water is used to leach the organic matter from the sand and direct it to the treatment plant for further processing
  • the washed sand is transported by an integrated screw conveyor to another container for further use or disposal.

The advanced technologies integrated in the Noggerath® sewage grit receiving station allow for an efficient solution to surface water management problems and environmental protection.
