ok Hydro"1r r"d South Relief Canal Algal Turf Scrubber@ Pilot Program The blended water shall be delivered at a maximum rate of about 20 gpm to the ATSTM automatic self-siphoning surge device at the ATSTm headworks which introduces water in pulse discharges to the floway . The delivery piping system shall allow for regulation of flow rate between 10 and 20 gpm . An in - line influent ultrasonic flow meter shall be used to document totalized flows of the canal water . The Utilities Department shall provide the pump and flow meter with totalizer associated with the RO Concentrate . The Utilities Department will also load the Concentrate Tank , if required , with fresh RO Concentrate . As noted , canal water inflow shall be blended with the RO Concentrate at a target ratio of 6 : 1 to 10 : 1 canal water to Concentrate and the blend provided to the MPU self- siphoning surger at an initial rate of 20 gpm . Flow rate and blend adjustments shall be made based upon actual field conditions and system performance . HydroMentia , Inc . under contract with Indian River County , shall operate the field test unit for a period of 6 months ( 26 weeks ) . HydroMentia ' s designated operational manager shall be experienced in conducting water quality sampling and maintaining records in conformance with FDEP ' s requirements per DEP- SOP- 001 /01 FS 1000 March 31 , 2008 (effective 12/3/2008 ) . Laboratory methods and MDL and PQL shall be as delineated within DEP- SOP- 001 /01 FS 1000 March 31 , 2008 (effective 12/3/2008 ) and Federal Register Vol 72 NO . 47 and as identified by the contracted laboratory ( ies) . The selected laboratory ( ies ) shall be NELAC certified and as accepted by FDEP . HydroMentia shall visit the site no less than once weekly during the course of the field investigation to provide required operational services . Operational services shall include operation and maintenance of equipment ; documentation of field conditions ; harvesting , documentation and management of algal turf harvest ; and recovery , preparation and delivery of water samples to a NELAC certified laboratory ( ies) . In -situ testing (field sampling for pH , dissolved oxygen , conductivity and temperature and monitoring flow , air temperature and rainfall ) shall be by HydroMentia . During the project , monthly update reports will be prepared that summarize system performance and include explanation of any operational adjustments . At project' s end , a final report shall be prepared and submitted for review . The final project report shall include a complete compilation and analysis of performance data for the six month field demonstration ( pilot) project . From this analysis , adjustments , if required , will be made to the system design , system performance and harvesting /composting projections for a conceptual full -scale Algal Turf Scrubber@ system to be applied to the PC - South Water Treatment and Re- Use Water Project . HydroMentia shall prepare modified Algal Turf Scrubber Design Model (ATSDEM ) runs , and these shall be included within the final project report . Plan of Study 13
