Greeley and Hansen, A TYLin Company, provided third-party review to evaluate water softening and sizing.
Greeley and Hansen assisted San Jose Water with a third-party review of the water quality section within an in-development report which included the evaluation of the assumptions, calculations, findings, and recommendations described in the report. The project team also provided additional guidance and recommendations to better define the water softening Proof-of-Performance pilot testing scope of work.
Greeley and Hansen subsequently prepared a preliminary process flow diagram, sizing and layout of a Reverse Osmosis (RO) or Nano- Filtration (NF) membrane treatment plant at Willow Glen Way Station that will address the known PFAS and hardness issues with the water. The project scope included review and comment of the in-development report, comments on technical and construction considerations, creation of preliminary design criteria for a RO system at Willow Glen Way Station, development of a process flow diagram (PFD), development of a system layout with changes to existing major components, development of an annual operational expenses, and determination of capital cost estimates for major RO/NF line items.
