Demonstration of Cost and Energy Efficient Novel Technologies for Decarbonization of Water Reclamation Systems

Funded by California Energy Commission (EPC-24-019) Budget: Approx 6.3 M

 

The principal objective of this project is to demonstrate the performance of innovative and more efficient water reclamation technologies by documenting their reductions in (1) electricity use, (2) green-house gas emissions, (3) space requirements, and (4) costs. The project involves applying five innovative technologies to produce two categories of reclaimed water: (1) non-potable unrestricted use water for applications such as irrigation, impoundments, and cooling purposes, and (2) potable water, which includes (i) indirect reuse employing an environment barrier (i.e., groundwater or surface water augmentation) and (ii) direct potable reuse (distribution after treatment without any environmental barrier).

 

The novel water reclamation technologies are demonstrated at three water resource recovery facilities in California operated by the following utilities: (1) Linda County Water District, (2) Los Angeles County Sanitation Districts, and (3) Silicon Valley Clean Water. Implementation of the following five innovative water reclamation technologies is evaluated in this project: (1) MITA cloth media filter, (2) Taron activated sludge filter (ASF), (3) BeFlow Continuous flow aerobic granular sludge process coupled with membrane bioreactor, (4) Ultrabore Ultra-Filtration Membrane, and (5) IMPACT-RO micro-disrupting parallel and cascading train reverse osmosis system. 

 

The project initiated in 2024 and will be completed in 2029.
