Solids Removal & Dewatering Unit (SRDU)

The SRDU system, renowned for its efficiency in solids removal, employs an innovative flocculation process to effectively eliminate suspended solids from wastewater. 

It excels as the primary step preceding further filtration processes. Engineered to separate suspended and colloidal solids from the liquid phase, this system employs a proprietary flocculation method that combines air and polymer injection, causing solids to float. 

What sets it apart is its capability to achieve these results with significantly lower power consumption, chemical usage, and space requirements compared to traditional Dissolved Air Flotation (DAF) systems.

Key Attributes of the Solids Removal & Dewatering Unit:

  • High efficiency injection of compressed air and polymer into the mixing system provides enhanced contact between solids and polymers.
  • Space efficient – about 2-4x smaller than a typical DAF (Dissolved Air Flotation) system.
  • Enhanced solids removal means cleaner effluent (<0.1% TSS typically).
  • Adaptability – can be adjusted to process different flow rates and is more tolerant of wastewater variations than a DAF.
  • Easy to start and stop without sacrificing effluent quality.
  • Typically uses 20%-50% less chemical than DAF systems.
  • Produces drier float and sludge for efficient solids removal and dewatering.
