Originally constructed as a 7.8 mgd facility in 2000, the facility was expanded in 2006 to 11.3 mgd, and
to 21 mgd in 2008. Improvements for this involved pilot / demonstration to increase the membrane flux from 54 to 80 gfd, addition of 2 MF units and evaluation of alternative coagulants to improve settling and membrane system performance.
Capacity: 21 mgd
SPI designed the improvements to the Pall system and conducted jar testing to select an alternative coagulant. The conversion from Alum to ACH is expected to save the District about $300K/year on chemical costs.
