DYNAMIC DRUM THICKENER WITH ARCHIMEDEAN SCREW
Innovative Thickening Solutions for Municipal and Industrial Sludge
TEKNOFANGHI’s SCRUDRAIN® dynamic thickeners with an Archimedean screw represent the state of the art in sludge thickening technology. Designed for use in both municipal and industrial applications, SCRUDRAIN® is the ideal solution for achieving higher dry solids (D.S.) concentrations prior to dewatering or further treatment.
Applications
- Pre-Thickening: Used before plate filter presses, belt filter presses, centrifuges, and drying beds to enhance dewatering efficiency.
- Biogas Reactors: Increases sludge concentration to improve reactor performance.
- Coarse Material Removal: Effectively filters and removes coarse materials, such as fibers, in the textile industry.
Performance
The SCRUDRAIN® thickener adjusts the sludge concentration by regulating the speed of the Archimedean screw, allowing sludge with 0.5-3% D.S. to be thickened to 5-15% D.S.. This flexibility ensures optimal results for various sludge types and processes.
TYPICAL APPLICATIONS:
- Municipal wastewater
- Industrial wastewater
- Food and beverage,
- Dairy farms and slaughterhouses
- Wineries and breweries
- DAF sludge
- Chemical industry
- Paper mill
- Drinking water, river and lake water
- Mineral, ceramic, glass
- Ground water remidiation
- Oil sludge
- Biogas
MAIN ADVANTAGES:
- Drum with Archimedean screw inside
- For a wide range of dry solids concentration
- Capture rate up to 98%
- Designed to contain maintenance cost
The SCRUDRAIN® sludge thickener delivers superior performance compared to conventional systems, achieving significantly higher thickening results. With the ability to handle sludge flows ranging from a few m³/h up to a maximum of 200 m³/h per single unit, the system offers unmatched versatility. Performance varies based on the sludge type and dry solids (D.S.) content, ensuring tailored solutions for diverse applications.
The standout feature of the SCRUDRAIN® sludge thickener is its Archimedean screw, which replaces the conventional empty drum design found in traditional systems. This innovative technology enables efficient thickening, allowing sludge with 0.5-3% dry solids (D.S.) to be increased to 5-15% D.S., depending on the sludge type.
During the washing phase, dirty particles removed from the process remain inside the drum thickener and are discharged along with the thickened sludge. This design ensures a particularly clean filtrate with a high efficiency capture rate of up to >98%, delivering superior filtration performance.
The filter cloth in the SCRUDRAIN® is maintained in optimal condition with an automatic washing system, featuring specially designed TEKNOFANGHI spray nozzles. These nozzles are engineered to consume significantly less water compared to standard options available on the market. For added convenience, the nozzles can be easily removed and cleaned without the need for tools, ensuring rapid maintenance and uninterrupted operation.
The filter cloth in the SCRUDRAIN® is designed for exceptional durability, as it is not subjected to tensile stress. Instead, it is directly fixed onto the Archimedean screw, reducing wear and extending its operational life. Combined with the robust and simple machine structure, these thickeners deliver unparalleled reliability and long-term performance.
The SCRUDRAIN® thickeners are delivered as fully equipped plug-and-play units, complete with a control panel, washing pump, and all necessary ancillary equipment for efficient operation. The control panel allows for complete automatic operation and is designed to interface seamlessly with other panels, providing signals to drive both the sludge pump and the polyelectrolyte pump.
To ensure a clean and user-friendly experience, the machine is fully enclosed, effectively preventing odour emissions and maintaining a controlled environment.
The SCRUDRAIN® can be customized with optional accessories to enhance performance and adaptability. These include:
- A reactor-flocculator to optimize the mixing of sludge and polyelectrolyte, ensuring efficient distribution inside the drum thickener.
- A dedicated tank for storing and transferring thickened sludge, complete with a level probe and a thickened sludge pump for seamless operation.
These accessories make the SCRUDRAIN® an even more versatile and efficient solution for a wide range of sludge thickening applications.
