BAG DEWATERING SYSTEM

Modular Dewatering Solutions for Every Type of Sludge

With over 40 years of experience, TEKNOFANGHI is the pioneer and world leader in the dewatering sludge sector with the patented TEKNOBAG-DRAIMAD® system.

This modular solution, based on the innovative TEKNOBAG-DRAIMAD® draining bag, has revolutionized sludge treatment in every type of plant, achieving:

  • 15-30% dry solids (D.S.) content after just a few hours.
  • 50-80% dry solids (D.S.) after a longer storage period.
Key Features
  • Optimized Design: The system includes a specialized stainless steel AISI 304L module, engineered to streamline bag filling and simplify movement operations.
  • Versatile Options: Available in various configurations to meet the needs of wastewater treatment plants (WWTPs), ranging from manual modules with 2 bags to automatic and pressurized systems with up to 12 bags.
  • High Capacity: The largest module can treat up to 20 m³/day of sludge, depending on its concentration.

The TEKNOBAG-DRAIMAD® system delivers reliable, adaptable, and efficient sludge dewatering, making it a trusted solution for municipal and industrial applications.

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

MAIN ADVANTAGES:​

  • Up to 70-80% DS
  • Zero wash water consumption
  • Negligible power consumption
  • Negligible maintenance cost
DEWATERING

The TEKNOBAG-DRAIMAD® system delivers efficient dewatering results. After just a few hours of operation, with proper sludge conditioning using polyelectrolytes, dry solids (D.S.) contents of 15-30% can be achieved, depending on the sludge type.

The volume of dewatered sludge produced varies based on the solid content of the incoming sludge. For example:

  • With sludge containing 1% dry solids, the system can process up to 20 m³/day.

This high-performance dewatering capability makes the TEKNOBAG-DRAIMAD® ideal for a wide range of sludge treatment applications.

DRYING

After the initial dewatering stage on the TEKNOBAG-DRAIMAD® system, the bags are sealed, removed using a special bag trolley, and stored in the open. During this secondary phase, the weight and volume of the sludge continue to reduce, regardless of weather conditions.

The water-repellent material of the bags prevents rainwater from entering while allowing dehydration through evaporation. Key results include:

  • 50% dry solids content achievable after two months of storage.
  • 70-95% dry solids content possible with additional storage time.

For example, 1 m³ of sludge with 1% solids content can produce a cake with at least 50% dry solids after two months, weighing only 20 kg—a 50-fold reduction in the original weight.

This innovative drying process makes the TEKNOBAG-DRAIMAD® an effective and sustainable solution for reducing sludge volume and weight.

DRAINING BAGS

At the core of the TEKNOBAG-DRAIMAD® system are the innovative draining bags, crafted from a special TNT water-repellent material. These bags are highly durable and resistant to:

  • Chemicals
  • Acids
  • Bacteria
  • Insects

This unique material ensures exceptional performance and longevity, making the draining bags a reliable component for efficient sludge dewatering and drying.

FLEXIBILITY

The TEKNOBAG-DRAIMAD® system offers unparalleled flexibility with approximately 30 different models available, ranging from small manual units to fully automatic and pressurized units.

Key benefits include:

  • Scalability: If additional sludge capacity is required, an extra bag module can be easily added and connected using the existing flange, minimizing costs and maximizing efficiency.
  • Adaptability: The system is designed to accommodate diverse operational needs, making it suitable for both small-scale and medium-scale sludge treatment applications.

This modular approach ensures that the TEKNOBAG-DRAIMAD® can grow with the demands of your wastewater treatment plant (WWTP).

PRESSURIZATION OPTION

The TEKNOBAG-DRAIMAD® system offers an optional pressurization facility designed to enhance efficiency and performance.

Key advantages include:

  • Reduced Dewatering Time: Pressurization accelerates the dewatering process, saving valuable operational time.
  • Increased Sludge Capacity: Higher dry solids concentrations are achieved inside the bags, allowing for a greater volume of sludge to be treated.
  • Cost Efficiency: By optimizing the process, pressurization reduces both working time and bag consumption, lowering overall operational costs.

This optional feature makes the TEKNOBAG-DRAIMAD® system an even more versatile and efficient solution for sludge dewatering.
