AWWA ACE 15 Conference attendees tour Dynatec's Decentralized wastewater treatment facility

The DynaLift™ pumps wastewater from a local sewer line, treats it for reuse and returns the waste activated sludge and screenings to the sewer line.

Water Mining in Anaheim, CA for reuse.

Dynatec provided the membrane system for a demonstration system situated directly adjacent to the Anaheim, CA City Hall.

The system is designed to pump water from a local sewer line, treat the water to high standards, and return waste activated sludge and screenings to the sewer line.

The DynaLIft out-of-basin membrane system was selected because:

  • The high flux rates achieved by the DynaLIft system allowed for a small footprint
  • The high MLSS concentrations employed require smaller reactor tanks
  • The positive filtration achieved with MBR eliminates plant upsets so consistent high quality discharge is achieved
  • The out-of-basin design allows for better demonstration of the technology
  • The membrane construction allows for high removal of bacteria and virus – demonstrated 5-log removal of bacteria is and 4-log removal of virus
  • The system meets California Title 22 requirements

 The plant design is for two trains with the first train presently in operation. Plant design is ultimately for 104,350 gpm when the second train is installed. The recycled water is used for irrigation and toilet flushing within the requirements of California’s Title 22 Regulations.

Plant automation design allows for periodic operator attention only when equipment maintenance or top-up of chemicals is required.

Following treatment in the MBR, the effluent is further treated using ozone followed by UV for ozone destruction and chlorine addition at 1 mg/L to ensure no re-growth in the final effluent.

Due to the proximity of City Hall and the fact that the plant is in a highly built-up area, a state-or-the-art odor control system was installed. When the standard Dynatec design is used and the location is not in such a critical area, odor control is not typically required.

This is the first facility in California to use external MBR membranes, ozone and chlorination for water recycling. The use of decentralized wastewater treatment facilities is increasing and the City of Anaheim is in the forefront of this.
