Inlet works solutions
Removing rag and debris from sewage inflows
Solids carried in wastewater can accumulate and cause clogging or damage in downstream processes. This can reduce plant efficiency as well as causing damaging abrasion to treatment systems - increasing operational and maintenance costs.
Our inlet works screens and screens handling packages remove debris and solids to protect downstream processes, cutting maintenance and preventing clogging and deposition. Our sludge management products improve dewatering and reduce solids handling.
We partner with market-leading third party manufacturers to ensure we deliver the most effective and reliable solutions.
Our teams of skilled engineers work with our clients to deliver bespoke design and installation solutions, along with high-quality, reliable maintenance and repair services, working with technologies that have been developed and improved over more than 40 years.
Noggerath® Combined Unit
The Noggerath® Combined Unit TOP is an entire headworks system that removes the need for separate pre-treatment equipment at wastewater treatment works. Installed at the inlet works, the unit combines fine screening, dewatering and grit separation.
Optional fat, oil and grease removal with the TOP-F range.
By integrating multiple processes into one system, the Noggerath® Combined Unit provides efficient pre-treatment from a small space and also simplifies installation by eliminating the need for separate systems.
The Noggerath® Combined Unit is available in non-aerated or aerated designs for installation above-ground or in channels and can also accommodate a wide range of screens such as step screens, fine sieves and rotary drum screens.
Applications
- Pre-treatment for municipal or industrial wastewater treatment
- Mechanical wastewater pre-treatment for membrane plants
- Septic sludge treatment

Noggerath® Septage Receiving Station
The Noggerath® Septage Receiving Stations are fully encapsulated systems that act as the first process point at inlet works of wastewater treatment plants.
The units mechanically screen faecal sludge, then convey, dewater, compact and discharge waste material. They are ideal for receiving septage sludge from tankers, receiving industrial wastewater and sludge screening.
The optional Noggerath® RED (Radial Eco Drive) technology for the Lower- and Medium-Capacity units ensures an axially free discharge area, meaning screenings are discharged without clogging.
With the Noggerath® Rotating Bar Screen – in the Medium-Capacity unit – the inlet zone is free of mechanical parts, improving hydraulic performance and making maintenance much easier.
For heavy-duty applications, the High-Capacity RSH-I-SRS unit offers very high throughput, reliable handling and internal feeding for a high volume of large solids.

Hydro-Sludge™ Screen
The Hydro-Sludge™ Screen is a superior sludge screening solution for municipal and industrial applications, delivering solid performance and straightforward maintenance.
Offering a range of screen sizes, the Hydro-Sludge™ Screen reduces loading on downstream processes and improves overall treatment effectiveness. Able to handle a dry solids capacity of up to 9%, the Hydro-Sludge™ Screen removes solids early on in the process, minimising the clogging that would otherwise reduce downstream treatment efficiency.

We offer a range of coarse screens which include:
KHU KN Multi-Rake Screen
A dual-angled coarse screen which requires no wash water to operate.
Kuhn KHU Boomerang XL Multi-Rake Screen
A reliable screen capable of handling maximum flow rates with the lowest possible hydraulic head losses.
Ideal for the widest flumes and lifting screenings up a significant height.
Kuhn KHU Multi-Rake Screen
Kuhn’s standard multi-rake screen is engineered for high-performance in demanding environments, delivering reliable operation under heavy loads and extreme conditions.
Kuhn SL Multi-Rake Screen
The Kuhn SL Multi-Rake Screen has the same high-quality build and component life as the KHU, but has been designed specifically for small and medium flumes. It offers a robust alternative to basket and spiral screens and flat fine screens.
Kuhn KGR Knuckle Rake Screen
The Kuhn KGR Knuckle Rake Screen is designed for installation in narrow flumes and shafts, including existing flumes without any specific hydraulic requirements.
Fine screens take and screen the effluent flow passed on from coarse screens, providing an additional, but essential protection level to downstream processes.
Our range of fine screens include our own in-house developed MNSS Combined Screens as well as by Passavant-Geiger, a Aqseptence Group company based in Aarbergen, Germany.
MNSS Combined Screen
The MNSS Combined Screen is a robust, reliable inlet works system that combines screening, washing, transport, compaction and dewatering in a single cost-effective standalone solution.
Developed by our UK Wastewater Services team, the MNSS Combined Screen is designed for smaller plants and those facilities that require a more cost-effective screening solution.
The MNSS Combined Screen is easy to install and is ideal for use in municipal or industrial applications that require a simple and robust solution to remove fine solids from a flow.

Noggerath® Centre-Flo CF WPS Band Screen
The Noggerath® Centre-Flo Band Screen CF WPS is a space-saving fine screen which delivers a Screenings Capture Rate of up to 85%.

Noggerath® Rotary Drum Screen RSI-RED
The Noggerath® Rotary Drum Screen RSI-RED is a compact machine which combines screening, conveyance and compacting. With separately driven screen drum and screenings conveyance systems, no suspended rotary arm is required, leaving a free inflow for the screenings.

Screenings from coarse and fine screens contain a high proportion of water and organic matter. The more water and organics that can be removed from the screenings, the more transport and disposal costs are reduced.
Our wash presses wash and dewater screenings, reducing their volume by up to 50%
Kuhn GmbH wash presses
KWP-HD (Heavy Duty) Wash Press
The Kuhn Wash Press KWP-HD is a high-quality machine for washing and separating out organic material from screenings. The Kuhn KWP-HD has an extra robust drainage desk along the bottom of the screw designed to withstand heavy duty operation. This drainage deck can be customised with 3 mm perforations or thin slot to improve screenings capture rate and reduce maintenance.
Grit in wastewater flows causes clogging in downstream processes making them less efficient. It also causes abrasion damage and wear on equipment, resulting in the need for increased cleaning, maintenance and repair.
Removing grit at the inlet works of wastewater treatment work will reduce maintenance costs and help ensure that more sensitive treatment processes can work to their maximum efficiency.
We offer a range of advanced products that can help wastewater treatment works operators effectively remove grit before it has the chance to enter other processes, erode expensive equipment, and deposit throughout a treatment plant.
Grit King®
The Grit King® is a compact, unpowered advanced grit management system that removes up to 95% of 106 μm particles or larger, preventing costly downstream grit abrasion and deposits.
With no moving parts, requiring less than 150 mm of headloss at average flows and a capacity to handle flows as low as 11 l/s, the Grit King® is a versatile and economical grit removal system that cuts plant maintenance costs.

Headcell®
The HeadCell® is an advanced stacked tray grit separator that retains 95% of all grit 75 μm and larger - guaranteed.
With a small footprint, no electrical requirements and no moving parts the HeadCell® delivers exceptional and economical solids removal for small, medium or large wastewater treatment plants.
