- Enjoy unmatched adaptability, with the ability to adjust to varying flow rates and wastewater compositions more effectively than traditional DAF systems.
- Reduce chemical usage significantly, typically requiring 20%-50% less chemicals compared to DAF systems, ensuring cost savings and environmental benefits.
- Produce drier sludge for easier handling and disposal, enhancing overall efficiency in wastewater treatment processes.
Incorporating advanced technology, the Solids Flocculation and Flotation System is meticulously designed for enhanced solids removal efficiency. Its adaptability allows it to efficiently process various flow rates while requiring significantly less chemical usage compared to conventional systems. With a smaller footprint and the capability to produce drier sludge, this system ensures both environmental compliance and cost-effectiveness in wastewater treatment processes.
Solids Floculation and Flotation System
- Better contaminant removal rates than DAF systems
- Adaptability–adjusts to higher flowrates
and higher contaminant levels without equipment changes. - Less chemicals–uses 20%-80% less chemicals than DAF systems
- Smaller Footprint–uses less space than other flotation and
flocculation systems. - Drier Sludge–the technology of using long chain polymers
produces drier sludge(8 to 13% drier and over 20% after decanting.)
