This paper outlines the steps of the decision making process associated
with adding membranes during a future plant expansion. The initial steps include
feasibility assessments to determine any site-specific or water quality challenges that may
eliminate membranes from further consideration. Next, preliminary design can reveal
site layout alternatives, pretreatment process requirements, and budget-level costs for
comparison to conventional treatment. If there are uncertainties with the treatment
process, pilot testing can be performed. Finally, a thorough evaluation of all significant
site and expansion issues (e.g., available space for future expansions, risk for future
regulatory compliance, plant hydraulics, etc.) can be made prior to embarking on design
of membranes for expansion.
The experiences of the Modesto Irrigation District (MID) are highlighted as an example
of how to navigate this decision-making process. With an expansion from 36 to 72 mgd,
membranes seemed a viable alternative to the existing conventional water treatment plant
(WTP) train at MID. Includes figure.
