The Gibson Island Advanced Water Treatment Plant (GIAWTP) applies state of the art
technology to treat domestic wastewater using sand ballasted clarification, microfiltration,
reverse osmosis, and advanced oxidation disinfection. The product water is used for direct
industrial reuse (potable substitution) and indirect potable reuse via existing reservoirs. This
plant is unique from the other two plants in the Western Corridor Recycled Water Program in
that it has the most restrictive footprint and utilized sand ballasted clarification (Actiflo) and has
two sources of secondary effluent: Luggage Point Wastewater Treatment Plant (WWTP), one
of the other AWTPs; and, Gibson Island Advanced Water Treatment Plant (GIAWTP). GIAWTP has conducted a series of bench and
pilot-scale tests over a two-year period which included: microfiltration (MF) performance
with and without sand-ballasted flocculation; reverse osmosis (RO) element comparison;
polymer evaluation; N-Nitrosodimethylamine (NDMA) formation; and, full-scale demonstration
tests. This paper presents results from two major efforts, the RO nitrogen removal performance
and NDMA formation tests, as well as comparisons of these bench/pilot-scale results to fullscale
performance. Includes 12 references, tables, figures.
