Discover the cost-effective and efficient Esmil Multi-Disk technology for sludge thickening. Our MDQ-T multi-disk sludge thickeners, part of Esmil Corp’s innovative equipment lineup, provide reliable, space-saving solutions for concentrating sludge from municipal and industrial wastewater treatment plants. These thickeners not only consume minimal energy, water, and reagents but also require minimal operator and maintenance attention.

The Significance of Sludge Thickening:

Sludge thickening plays a pivotal role in the wastewater treatment process. It involves increasing the sludge’s concentration before subsequent steps, resulting in a significant volume reduction (5-10 times less). Typically, initial sludge contains 0,2-1,2% DS, which can be increased to 5-8% DS or even 16% DS after thickening. Here’s why thickening is essential before anaerobic digestion, ATSO, RSO, and other technologies:

  • Enhanced Dewatering: Higher sludge concentration before dewatering allows for increased screw press capacity and potentially increase cake dry solids content.
  • Optimized Processes: Achieving the desired sludge concentration is vital for various processes, such as fermentation and others.

Application of MDQ-T Esmil Multi-Disk Sludge Thickeners:

Our MDQ-T multi-disk sludge thickeners find applications in diverse industries, including:

  • Wastewater treatment facilities
  • Biological treatment facilities at industrial enterprises
  • Biogas production

Technical and Technological Advantages of Esmil Multi-Disk Sludge Thickeners:

  • High Performance with Minimal Reagent Consumption: Our equipment efficiently utilizes reagents, with real-time monitoring and adjustment of flocculant doses. This results in effective thickening with minimal polymer usage (2.2-6.6 Lb of active matter).
  • Effective Thickening and Low Operating Costs: Designed by adapting MDQ dewatering drum technology, the MDQ-T offers efficient dewatering, low energy consumption, and minimal maintenance. It can handle challenging sludge types, including oily and difficult sludge.
  • Compactness: Our sludge thickener’s compact design saves space, making it suitable for installations with limited available area.
  • Versatility: The MDQ-T is versatile and can also effectively operate in dehydration mode when necessary, offering cake dry solids of 5-16% depending on the initial sludge type and concentration.
  • Ease of Use and Maintenance: Our equipment is user-friendly and requires only routine monitoring and washing. All components are easily serviceable, ensuring reliability and longevity.
  • Corrosion Resistance: Built with AISI304 or AISI316 stainless steel, the MDQ-T is highly corrosion-resistant and designed for long-term use without generating vibrations.
  • Comprehensive Automation: Esmil equipment is fully automated, enabling precise control over various aspects of the process, including polymer preparation, pump operation, and more.
  • Auxiliary Equipment: Our MDQ-T multi-disk screw thickeners are supplied with a range of auxiliary equipment, including pumps, flowmeter, macerators, conveyors, and flocculant feeders.
