Full Description

The City of Sunrise's Southwest Wastewater Treatment Facility (SWWWTF) was investigating theoption for upgrading the plant to meet advanced wastewater treatment (AWT) levels advancedtechnologies in order to treat wastewater to the level required for groundwater recharge through the useof rapid infiltration basins or trenches. The objective of this pilot study was to determine if these AWTtechnologies could be used to convert the City's SWWWTF to treat the raw wastewater to a levelrequired for groundwater recharge in Broward County. Chapter 27, Water Quality Standards of the Codeof Broward County, Florida, requires that any discharge to the groundwater must meet Total Phosphates(PO4-P) concentration of less than 10 g/L (parts per billion). This pilot study specifically evaluated themultiple treatment trains combining BNR-MBR technology, reverse osmosis (RO), and chemicalphosphorus removal at pilot scale and performed cost analysis for commercial "scale-up" application oftreatment alternatives to full-scale wastewater reuse application. Pilot results indicated that the controlstream removed orthophosphate to the levels of 10 g/L 15% of the time and 100 g/L 75% of the time.Stream A removed orthophosphate to less than 8 g/L 100% of the time. Stream B effluent showedorthophosphate levels of 10 g/L 35% and 100 g/L 96% of the time on single sample basis and levelsof 15 g/L on an average basis. This data was then incorporated to develop an economic evaluation of afull-scale treatment process, along with the regulatory requirements associated with the proposedtreatment processes. Includes 10 references, tables, figures.
