(2) 4-20 mA OutputsWhere is the HYDRA Used??Municipal Waste Water Treatment Plants? Primary Clarifier? Aeration Basins? Aeration Basins? Secondary Clarifier? De-Nitrification? Effluent?Environmental Waters? Lakes, Streams, Rivers? Agricultural RunoffPrimary Clarifier ? Primary Clarifier? Nitrogen in waste water is primarily Ammonia/Ammonium? The HYDRA-NH4measures the Total amount of NH3/NH4+, the Nutrient Load, going to amount of NH3/NH4 , the Nutrient Load, going to the Aeration Basin ? Nutrient Load determines the? Aeration requirement of the basin? Activated Sludge requirement of the basinAeration Basin? The Nitrification Process changes Ammonium, NH4+ into Nitrate, NO3-? The Microbes that perform this oxidation chemistry are suspended in the Activated Sludge? Adding Activated Sludge ? Adding Activated Sludge adds capacity? Increases Turbidity (TR8)? Nitrification is an Aerobic process? High O2 yields High Nitrification? The microbes respire and perform the oxidation? Adding Nutrient or Sludge increases the O2 demand (DO8)Aeration Basin? Optimize the Nitrification? Real time NH4+ ? NO3-? High Nutrient Load infers a High O2 requirement? The Nitrification rate is proportional to the O2 ppm? Adding O2 uses more power but lowers the time needed for Nitrificationbut lowers the time needed for Nitrification? Use Hydra-NH4 to control aeration? Low NH4+: minimal aeration even though O2 is Low? Higher NH4+: aeration under O2 Sensor control ? Nitrification Complete? Reduce the Aeration for Anoxic Denitrification or send to the Clarifier Secondary Clarifier ? Secondary Clarifier? All the NH4+ has been converted to NO3-? The Activated Sludge (AS) settles out and is either? Returned to the Aeration Basin (RAS) or? Sent to Waste (WAS)? HYDRA-NO3 measures the ? HYDRA-NO3 measures the Nitrate in the Clarifier in preparation of Anaerobic Denitrification? In Denitrification the microbes are starved of O2 and coerced to metabolize the Oxygen from the NO3 releasing Nitrogen gas? Anoxic (low O2)? Anaerobic (no O2)Anoxic Basin, SBR? Sequential Batch Reactor? SBR cycles between Anoxic and Aerobic, all in one vessel or sequence? Separate aerator and a mechanical mixer? HYDRA-NH4 and HYDRA-NO3are both usedare both used? Nitrification (Aerobic)? Aeration ON? NH4 ? NO3 ? ? Denitrification (Anoxic)? Aeration OFF, Mixer ON? NO3 ? N2 gas ?? small amount NH4 ? ? Nutrient Removal Phosphate? Aeration ON? Sludge Absorbs PO4? NH4?, NO3?, PO4 ? Anaerobic Denitrification? Nitrate from Secondary Clarifier is reduced to Nitrogen Gas? Denitrification requires to zero ppm Oxygen environment? Methanol is used as a carbon source to drive the carbon source to drive the microbes to Denitrify by increasing the COD? HYDRA-NO3 allows feed forward control of the Methanol addition based on Nitrate Concentration and Flow rate.? Accurate Methanol dosing saves moneyFinal Effluent & Environmental? HYDRA-NH4 and HYDRA-NO3 can be used to monitor the Total Nitrogen in the effluent. ? This is not an Approved method for reporting per 40 CFR Part 136 (NPDES, wastewater)? SM 4500-NO3- D (18, 19, 20th &2000) is the ISE ? SM 4500-NO3- D (18, 19, 20th &2000) is the ISE based Method? It requires sampling and the addition of a conditioning reagent to eliminate interferences from Chloride, Nitrite and bicarbonate.? The HYDRA-NH4 can be used to monitor the agricultural NH4+ run off into Lakes and StreamsHYDRA Analyzer Features?

Connect a solenoid controlled ¼” air line to the HYDRA tube fitting. (feed the air tube through the Immersion Assembly)? Connect the immersion assembly (1 ¼” FNPT) to the HYDRA Sensor. Sensor. ? Insert the sensor into the tank and attach the HYDRA using the Handrail Mounting Kit? Wire the Sensor, the Outputs, the solenoid to Relay 1, and supply power.? See the Output Default Ranges in the Instruction Manual, adjust if necessary.Start Up Guide? The HYDRA is up and running? The Air Blast spray cleaner will actuate once every hour for 10 seconds to keep the measuring electrodes clean? Wait several hours for the sensors to equilibrate to the Process conditionsthe Process conditions? Verify readings versus a laboratory test and Standardize the reading if necessary? Visually inspect the sensor for coating weekly and verify calibration versus laboratory measurement.Electro-Chemical DevicesContact ECD For over 30 years Electro-Chemical Devices (ECD) has been a recognized leader in industrial process instrumentation: Liquid analytical sensors, controllers, transmitters, analyzers and electrodes. analyzers and electrodes.
