Advanced, Cost-Effective Sludge Treatment Solutions

Sludge is a byproduct of wastewater treatment, and handling it efficiently is critical to keeping costs down and meeting environmental regulations. We design, build, and upgrade sludge treatment plants (STPs) that focus on reducing volume, extracting energy, and ensuring safe disposal or reuse. Our solutions include thickening, dewatering, digestion, biogas production, drying, incineration, and composting—all designed for low operating costs and maximum efficiency.

Our Sludge Treatment Services

Sludge Thickening & Dewatering

By removing water early in the process, we cut down on transport and disposal costs. Our dewatering systems deliver high dryness levels with minimal energy and chemical use.

  • Thickening reduces sludge volume before further processing
  • Dewatering removes excess water to cut disposal costs
  • Centrifuges, belt presses, and screw presses for effective water removal

Sludge Digestion & Biogas Production

Instead of treating sludge as waste, we turn it into renewable energy. Our digesters produce methane-rich biogas, which can power plant operations or be fed into the energy grid.

  • Anaerobic digestion breaks down sludge and produces biogas
  • Biogas cogeneration generates electricity and heat (up to 650 kW capacity)
  • Sludge volume is reduced, and energy is recovered

Sludge Disintegration & Process Optimization

Disintegration makes sludge easier to process, cutting costs and boosting energy recovery. The result? Less waste, more energy, and lower disposal fees.

  • Mechanical and ultrasonic disintegration improves breakdown
  • More efficient digestion = higher biogas yield
  • Reduces excess sludge production

Sludge Drying & Incineration

Drying and incineration offer a complete solution for sludge disposal, particularly where land application is not feasible. These methods significantly reduce sludge volume and create energy recovery opportunities​.

  • Thermal drying reduces sludge weight and kills pathogens
  • Incineration ensures complete sludge disposal while recovering energy
  • Heat recovery systems improve efficiency and reduce fuel use

Sludge Composting & Agricultural Reuse

When properly treated, sludge can be safely reused as fertilizer or soil improver, reducing the need for chemical fertilizers and closing the resource loop​.

✔ Aerobic composting transforms sludge into a nutrient-rich soil conditioner

✔ Stabilized sludge can be used in agriculture, landscaping, and land reclamation

✔ Complies with strict environmental and agricultural regulations
