System solutions for water, wastewater and sludge treatment
Specialized Sludge and Waste Treatment
In the rapidly growing Norwegian aquaculture sector, the challenge lies in balancing growth with environmental commitments. Norditec specializes in Sludge Dewatering Process (SDP) solutions, developed for land-based fish farming. Our systems handle everything from primary mechanical filtration (particles < 1 mm) to multi-stage dewatering and drying, transforming waste into a manageable resource while maintaining the delicate biological balance of Recirculating Aquaculture Systems (RAS).
Xripper/grinder
XRipper is a twin-shaft grinder designed to reduce fibres, fibres and other disruptive solids in liquid media. The grinder can be used upstream of pumps and other process equipment where solids may cause blockages, downtime or damage to the equipment.
Emptying Stations
Solutions for receiving and pumping septic and waste water from boats. Emptying stations can be installed on quays or in marinas and tailored to the required capacity, pipework, choice of pump and conditions at the installation site.
Diesel-Powered Pump Sets
Diesel-powered pump sets for pumping where a fixed electrical infrastructure is not available or impractical. The solution is selected based on the medium, the required capacity, the head, the suction conditions and the operating environment.
XSplit – screw press separator
The XSplit from Vogelsang is a screw press separator designed to separate solids from liquids. It may be suitable where sludge or other pumpable media need to be dewatered prior to further handling, transport or treatment. Capacity and achievable dry matter content depend on the medium and the configuration.
What should be considered before choosing a system solution?
A good solution starts with the right process data. Before selecting equipment or process steps, the following should be clarified:
- Medium, wastewater or sludge type
- Quantity and type of solids
- Required capacity and desired treatment outcome
- Inlet and outlet conditions
- Available space and installation conditions
- Existing equipment before and after the solution
- Access to electricity or the need for motorised operation
- Need for a mobile or fixed installation
- Operational and maintenance requirements
- Any hygiene, environmental or regulatory requirements
Any hygiene, environmental or regulatory requirements. The information is used as a basis for technical assessment and design. The final solution must be adapted to the specific application.
System solutions for various sectors
Aquaculture and land-based fish farming
Sludge handling, separation and dewatering tailored to the plant’s treatment process and the type of sludge.
Water and drainage
Grinding, pumping, separation, flotation and UV treatment, where the technology is suited to the process requirements.
Biogas
Grinding and separation may be relevant for the treatment of substrate and digestate (residual material from biogas production) provided that the equipment in question is suitable for the medium and the process.
Industry
Solutions for the pumping, separation and treatment of process media, based on the properties of the media and operational requirements.
Port and marina
Emptying stations and pumping solutions for handling septic and waste water from boats.
Sludge treatment for land-based aquaculture
Sludge from land-based fish farming may require several treatment stages before further processing. The most suitable solution depends, amongst other things, on particle size, sludge concentration, water volume, the desired dry matter content and the design of the facility’s existing treatment process.
Norditec can combine relevant types of equipment and process stages as required, from pre-treatment and separation to dewatering. The final solution should be designed on the basis of actual process data and the desired outcome.
Frequently asked questions about system solutions
It depends on the type of sludge, water content, solids content, capacity and the desired dry matter content. A screw press separator such as XSplit may be suitable for certain applications, whilst other plants may require multiple process stages. Norditec should assess the process data before a final solution is selected.
A grinder may be required when fibres, shreds or other solids cause blockages or place a strain on pumps and other equipment. The type and location of the grinder must be assessed on the basis of the medium, particle type, capacity and the layout of the plant.
Continuous H₂S monitoring is carried out using a sensor selected for the appropriate medium and measuring point. The data can be used for trend monitoring, alarms, odour and corrosion control. A screw press separator performs a specific process step: the separation and dewatering of solid and liquid materials. A sludge treatment solution may consist of several stages, such as pre-treatment, separation, dewatering and further handling. Which stages are required depends on the plant and the sludge. control and other process tasks where the system supports this.
A diesel-powered pump set may be appropriate where electricity is not available, where pumping is temporary or mobile, or where the installation requires an independent power source. The pump must be selected on the basis of the fluid, capacity, head and suction conditions.
Flotation plants are used to separate particles and other separable fractions from water using air bubbles. Whether flotation is suitable depends on the composition of the water, the desired degree of purification and the rest of the process.
UV disinfection may be appropriate when microorganisms in water need to be inactivated without the use of chemical disinfection. The choice of system depends, amongst other things, on water quality, flow rate, how well UV light passes through the water (UV transmittance) and treatment requirements.
Please provide details of the medium or sludge type, capacity, quantity and type of solids, the desired outcome, available space, existing equipment and relevant operating conditions. The more detailed the process data provided, the easier it is to assess the appropriate equipment and the next steps.
