The Work is more particularly described below . 1 Algal Turf Scrubber® Field Investigation ( Pilot) Program Introduction The pilot scale investigation of the Algal Turf Scrubber@ (ATSTM ) will simulate the ATSTM treatment process specific to the water quality conditions associated with the blending of water from the South Relief Canal and a Reverse Osmosis Concentrate Water . The results will be used to ( i ) refine periphyton growth and water treatment projections and ( ii ) optimize the design of a full -scale Algal Turf Scrubber@ Water Pollution Control Facility . The CONSULTANT shall furnish , install , and operate a pilot scale ATSTM system for a 6 - month period . Influent water shall be a blend of water from the South Relief Canal ( managed by the Indian River Farms Water Control District or IRFWCD) and an RO concentrate generated by the Indian River County Utilities Department ( Utilities Department) . The blend will be such that it is emulative of the expected mix when the two waters are introduced through discharge of the concentrate into the South Relief Canal . This blend is expected to be 6 : 1 to 10 : 1 canal water to Concentrate . The Algal Turf Scrubber@ Mobile Pilot Unit ( MPU ) will be as shown in Figure 1 : The MPU consists of an aluminum ATSTM floway with support structure , self- siphoning surger , effluent box , 40 mil EPDM base , and a geotextile grid . ® The MPU floways shall be installed at a design slope of 0 . 5 % . The floway shall have a width of 1 feet and a length of 500 feet . ® Inflow water samples shall be collected weekly from the surger reservoir via a time interval refrigerated autosampler and via grab samples for short hold time parameters . ( See Table 1 ) i Outflow samples shall be collected weekly from the effluent sump via a second time interval autosampler and via grab samples for short hold time parameters . ( See Table 1 ) S Water from the South Relief Canal will be analyzed for key parameters via grab samples collected biweekly . ( See Table 1 ) Concentrate will be analyzed for key parameters via grab samples collected biweekly . ( See Table 1 ) Testing required through the FDEP Permit 31 FL0037940 issued to the Utilities Department will be collected via a third autosampler .

INTRODUCTION A number of treatment technologies have been developed that provide nitrogen and phosphorus ( nutrient) removal from stormwater ( nonpoint source ) and/or advanced level nutrient control for wastewater ( point source) effluents or sidestreams . Plant based biological systems that include ( i ) treatment wetlands and ( ii ) managed aquatic plant systems ( MAPS ) have been applied to both point and non - point source applications , while bacteria based biological systems including ( iii ) biological nutrient removal ( BNR ) , ( iv) enhanced biological phosphorus removal ( EBPR ) , and (v) the modified Renphosystem , among others are applied almost exclusively to wastewater associated point source applications . Managed aquatic plant systems ( MAPS ) have been developed , and are now commercially available . MAPS dynamics revolve around direct nutrient uptake by cultivated aquatic plants and subsequent removal and recovery through harvesting and processing of the plant biomass . This approach offers reduced land area requirements when compared to " passive" treatment wetlands , while providing quantifiable removal , recovery and reuse of captured nutrients and effective enhancement of water quality through increased dissolved oxygen levels and attenuation of other pollutants , such as metals and hydrogen sulfide . One specific MAPS technology known as The Algal Turf Scrubber® or ATSTM is being considered by Indian River County ( COUNTY) as a reasonable approach to management of a combined wastestream composed of 1 ) about 1 MGD Reverse Osmosis ( RO ) concentrate from a water treatment unit owned and operated by Indian River County Utilities and 2 ) about 10 MGD of canalized stormwater associated with the Indian River Farms Water Control District ( IRFWCD ) South Canal . The RO concentrate is a mineralized water with a conductivity of about 6 , 000 microS/cm , and comparatively low nutrient levels . 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) . ' The canalized stormwater typically is characterized by lower conductivity levels ( < 1 , 000 microS/cm ) but higher nutrient concentrations . Presently , management requirements associated with the RO concentrate are delineated with an FDEP Permit 31 FL0037940 and the associated Consent Order 08- 1661 . The requirements for nutrient reduction within the South Canal stormwater flows are associated with the recent Total Maximum Daily Loads (TMDL) determinations . 2 The Algal Turf Scrubber® or ATSTM 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 ( Illustration 1 ) . Cultivation of the algal turf is sustained through periodic harvesting , which facilitates general improvement of water quality , including predictable reduction of nitrogen and Consent Order 08- 1661 executed September 19 , 2008 . 2 Total Maximum Daily Load for Northern and Central Indian River Lagoon and Banana River Nutrients and Dissolved Oxygen April 2007 .

Also , as noted , effluent from the ATSTM process is highly oxygenated , usually exceeding saturation during the daytime , and above 5 mg /I dissolved oxygen ( DO) during the nighttime . The high level of oxygen eliminates toxic influences typically associated with low DO , reducing environments , including the presence of un - ionized hydrogen sulfide and ammonia . In summary , the ATSTM technology was specifically developed to offer low cost treatment even under low nitrogen and phosphorus conditions , and is well suited for both stormwater and advanced wastewater treatment applications , and is a reasonable candidate for resolution of nutrient and toxicity issues associated with the South Canal stormwater and the RO concentrate as previously mentioned .

Compost Piles Illustration 2 : Typical Algal Turf Composting Operation 2 . 0 ALGAL TURF SCRUBBER@ PILOT PROGRAM PLAN OF STUDY Full scale Algal Turf Scrubber@ systems are typically composed of the following : 1 . Influent flow delivery system , which may be a low head , high flow pumping system (e . g . axial flow or Archimedes pumps ) , or a gravity conveyance system in association with a natural or structural drop in water level , (e . g . control structure , locks , reservoirs , etc . ) 2 . Intermittent release control devices or flow surger , designed to pulse flows in a manner emulative of oscillatory waves . This device is an automatic siphon mechanism placed on a surger box . The intermittent surging of water helps disrupt the algal cell wall boundary which enhances the rate of diffusion of nutrients , particularly at low concentrations . 3 . An influent distribution system designed to distribute water equitably along the width of the ATST"' floway , with flow introduced from the flow surger . 4 . A sloped ATSTM floway that typically includes a compacted soil sub- base upon which is laid an HDPE geomembrane , and over which is installed a geotextile grid , which serves as an attachment matrix for the algae . Floway length is typically no less than 250 feet , with the actual length being determined by treatment requirements and influent characteristics . Plan of Study 3 fs . Hydro"1r n io South Relief Canal Algal Turf Scrubber® Pilot Program 5 . An effluent and harvest flume that runs the full width of the ATSTM floway . Typically this flume is triangular in cross section , with a variable cross sectional area , increasing as flows accumulate . The slope is designed to solicit a velocity of at least 1 . 5 fps throughout the flume , which ensures conveyance of the harvested material . The flume serves both as a means to move effluent , and , during harvest , to transport harvested algae to an automated self cleaning bar screen ( Flex- Rake ) . 6 . An automatic Flex- Rake , typically as manufactured by Duperon Corporation of Saginaw Michigan (see Illustration 2 ) . The Flex- Rake facilitates capture and removal of harvested algae filaments , as well as continuous removal of sloughed algae and incidental solids . More elaborate secondary solids removal devices ( e . g . hydroscreen , wedge wire screens , filters etc . ) may be necessary in some cases . 7 . Algae harvest equipment for dislodging and moving excess production into the effluent flume 8 . Algae harvest processing and storage area , e . g . windrow compositing area .

Effluent Discharge Line Figure 1 : Typical ATSTm Layout Schematic ( NTS ) Plan of Study 5 South Relief Canal Algal Turf Scrubber® Pilot Program While certain planning decisions and cost estimates can be made through modeling and desktop assessments for water treatment technologies , there are certain limitations on the level of accuracy and degree of certainty that can be provided through these types of assessments . Field demonstrations or pilot studies allow the Engineer and Operator to evaluate the performance of proposed treatment systems under site-specific conditions . Data gathered from pilot studies are introduced into the planning and design process so that appropriate , defendable design refinements can be made . The result is better design of a more efficient system ; more reliable cost estimates ; and an enhanced understanding of the process dynamics . A pilot scale investigation of the Algal Turf Scrubber® (ATSTM ) is recommended to simulate the ATSTM treatment process specific to the water quality conditions associated with South Canal water blended with the Reverse Osmosis Concentrate . The results will be used to ( i ) verify periphyton growth and water treatment performance developed through initial projections and ( ii ) optimize the design and operational strategy of a proposed full -scale Algal Turf Scrubber® Water Pollution Control Facility . The pilot unit shall be a standard 1 foot wide aluminum floway as provided by HydroMentia as a Mobile Pilot Unit or MPU ( see schematic as Figure 2 ) . A typical MPU installation (as installed in the Everglades for the South Florida Water Management District) is shown as Illustration 3 . The proposed length is 500 feet . On possible location for the South Relief Canal pilot scale ATSTM just east of the intersections of Old Dixie Highway , 1 " Place , and the South Relief Canal , with the headworks of the pilot unit to be near the coordinates 27 ° 36 ' 14 . 22 " N and 80 ' 23 ' 11 . 84 "W. A schematic plan view overlain upon a Google Earth view of the proposed site is shown as Illustration 4 . It may be necessary to move the site to the west to accommodate more efficient access to electrical power and to canal water which has not been pre-mixed with RO concentrate . In addition , the RO Concentrate storage units as noted may not be needed if the system is cited close enough to the existing RO Concentrate line that a direct tap could be facilitated . Typical Elevation and Section schematics are shown in Figure 3 and 4 . The exact layout and facilities location will be developed in the field in coordination with the IRFWCD . The facility is to be operated for a 6- month period . Influent water shall be a blend of water from the South Relief Canal and the RO Concentrate generated by the Utilities Department of Indian River County . The blend will be such that it is emulative of the expected mix when the two waters are introduced through discharge of the concentrate into the canal . This blend is expected to be from 6 : 1 to 10 : 1 Canal Water to Concentrate . The South Relief Canal ATSTM Pilot Facility shall include the following components . The MPU consists of an aluminum ATSTM floway with support structure , self- siphoning surger , effluent box , 40 mil EPDM base , and a geotextile grid • The MPU floways shall be installed at a design slope of 0 . 5 % . The floway Plan of Study 6 Hydro:^1e,r .. South Relief Canal Algal Turf Scrubber@ Pilot Program shall have a width of 1 feet and a length of 500 feet . • A Pacer (or approved equivalent) self priming centrifugal pump will be located at a station contiguous to the South Relief Canal , complete with flexible intake hose , a slotted intake manifold properly secured with ground anchors ; PVC force main with check valves , recycle return lateral with valving , sampling lateral with valving , and influent force main with 2 " ultrasonics flowmeter with totalizer . • Either a 20 , 000 gallon tank for storage of RO Concentrate , with common outlet manifold and quick disconnect and valving to intake of small centrifugal or diaphragm type pump , with propeller type flow meter and throttling valving as supplied by the Utilities Department , or a force main extending from a tap into the existing RO Concentrate force main to the Pilot Facility , to include the appropriate valving and metering units . A sufficiently sized force main will deliver RO Concentrate to the ATSTM surger . • 120V , single phase power shall be provided at influent and effluent stations as well as the two pump stations . • A temporary , 6 foot chain link fence with locked gates shall be placed around the facility . • A gravity effluent discharge line with a 2 " ultrasonics flow meter identical to that used on the influent line , for delivery and monitoring of ATSTm effluent to the downstream reaches of the South Relief Canal . • An influent sampling station and an effluent sampling station will be included and shall be designed to support operations and to house and protect two refrigerated composite automatic samplers . A third sampler , which can hold the collection bottle in ice will be used for sampling for chronic bioassays of ATSTm effluent . • ATSTM Influent will be introduced at an approximate rate of 20 gpm , and will be a 6 : 1 to 10 : 1 blend of South Canal water (= 18 . 2 gpm ) and RO Concentrate (= 1 . 8 gpm ) . • ATSTM influent and effluent samples shall be collected weekly from the influent surger reservoir and from the effluent box via two refrigerated time interval autosamplers and via grab samples for short hold time parameters . The third sampler will be used to collect 24 hr composite samples for chronic bioassay on ATSTm effluent ( See Tables 1 and 2 ) . • Bi -weekly grab samples from RO Concentrate , Canal Influent and ATSTM influent for parameter note in Tables 1 and 2 to include selected parameters presently required by Permit 31 - FL00039740 , except for bioassays . Plan of Study 7 Hydro rice South Relief Canal Algal Turf Scrubber® Pilot Program • RO Concentrate will be sampled biweekly as grab samples for bioassay associated with the shrimp Mysidopsis bahia • RO Concentrate will be sampled as grab samples at project initiation , mid - term , and project end for bioassay associate with Menidia berrylina . • The ATSTm effluent will be sampled bi -weekly for three samplings as a minimum , as a grab sample , for acute toxicity testing using bioassay with the species Pimephales promelas (fathead minnow) and Ceriodaphnia dubia (daphnia ) . • The ATSTm effluent will be sampled bi -weekly for three samplings as a minimum , as composite samples , for chronic toxicity testing using bioassay with the species Pimephales promelas (fathead minnow) and Ceriodaphnia dubia (daphnia) . This chronic testing will be initiated only after three consecutive acute tests determined to meet FDEP criteria as non -toxic . • Algal turf biomass will be harvested periodically (typically every week or every other week) . The harvested biomass will be weighed in the field , and solids content determined from composited grab samples for each harvest . These dried composite samples will be combined and analyzed as monthly composites for nutrient content . • Flow meters will be placed upon the RO concentrate flow ( by Utilities Department) , the South Canal flow ( HydroMentia ) and the effluent flow ( HydroMentia ) . Totalized flows will be recorded weekly . Influent flows will be calculated as the sum of the two flow meter totalizers over the same time period . • A rain gauge will be placed on site and recording documented weekly , along with air temperature . • In - Situ pH , conductivity/salinity , DO and water temperature will be taken weekly using a YSI -590 ( or equivalent) handheld unit .
