Solids Removal & Dewatering Unit (SRDU)

The SRDU system is an efficient flocculation process to remove suspended solids from wastewater and serves well as an initial step prior to additional filtration. The system is designed to separate suspended and colloidal solids from liquid using a proprietary flocculation process that combines air and polymer injection to float solids using lower power, chemical and space requirements than a traditional Dissolved Air Flotation (DAF) system.

Key Attributes of the Solids Removal & Dewatering Unit:

  • High efficiency injection of compressed air and polymer into
    mixing system provides enhanced contact between solids and
  • Space efficient – about 2-4x smaller than a typical DAF
  • Enhanced solids removal means cleaner effluent (<0.1% TSS
  • 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


Multi-Disk Press Dewatering System

  • Stainless steel discs with abrasion resistant coating rotate to
    squeeze water out of flocculated solids
  • Creates a cake-like product ideal for land application or further
    processing into fertilizers, soil amendments, or biochar
  • Made in the USA
