South Relief Canal Algal Turf Scrubber@
1 . INTRODUCTION
The Indian River County Utilities Department , in cooperation with the Public Works
Department , Stormwater Division , have indicated intent to implement a water treatment
facility to be located contiguous to the Indian River Farms Water Control District' s South
Relief Canal within Indian River County—this canal being a major tributary within the
network of canals managed by the Indian River Farms Water Control District ( IRFWCD ) .
This proposed treatment system is to be designed around the application of an Algal Turf
Scrubber® (ATSTM ) ' to remove nutrients and eliminate toxicity associated with a blend of
an RO concentrate , as generated by the Utilities Department in the production of potable
water, and surface waters associated with the South Relief Canal ( South Canal ) . The
proposed treatment facility is referred to as PC South – Phase 1 . The RO concentrate is a
mineralized water with a conductivity of about 6 , 000 microS/cm , and comparatively low
nutrient levels . The canalized stormwater within the South Canal is characterized by lower
conductivity levels ( < 2 , 400 microS/cm ) but higher phosphorus concentrations . Indian River
County is coordinating with the FDEP to resolve concerns regarding the concentrate related
to nutrient and salinity loads and intermittent toxicity revealed through bioassays with Mysid
shrimp ( Mysidopsis bahia) . 2 Presently , management requirements associated with the RO
concentrate are delineated within FDEP Permit 31 FL0037940 and the associated Consent
Order 08 - 1661 , as well as applicable limits delineated within the latest update of Ch 62-302
F . A. C . The expected requirements for nutrient reduction within the South Canal stormwater
flows are associated with the impending Total Maximum Daily Loads (TMDL)
determination s . 3
On September 7 , 2010 , Indian River County authorized HydroMentia to conduct a
comprehensive PC- South ATSTM pilot study . This study was designed to facilitate
assessment of system performance in terms of both nutrient reduction , and toxicity
attenuation . The pilot program was rendered operational on January 17 , 2011 . The facility
was sustained operational to June 7 , 2011 . Data obtained during this period will be used in
developing the permit application for the proposed treatment facility .
The Utilities Department has requested a services and cost proposal from HydroMentia for
completion of FDEP permit applications for the proposed water treatment facility . This
proposal has been prepared in response to this request, and includes specific tasks and
associated costs attendant with efforts needed to develop a complete application as related
to the FDEP Wastewater Application Form 2CS — " PERMIT TO DISCHARGE PROCESS
WASTEWATER FROM NEW OR EXISTING INDUSTRIAL WASTEWATER FACILITIESTO
SURFACE WATER" .
The Algal Turf Scrubber® orATSTM is an engineered system composed of a sloped expanse of high density
polyethylene ( HDPE) geomembrane overlain with a synthetic grid matrix . Water is distributed across the
sloped floway in a shallow laminar flow , which provides ideal conditions for the development of an algal turf
community
