Preface

Total nitrogen (TN) and total phosphorus (TP) have been defined as “Living EnvironmentItems” under Environmental Quality Standards and Effluent Standards as part of measures tocontrol eutrophication of enclosed bodies of water. In addition to existing COD (chemicaloxygen demand), total nitrogen and total phosphorus were incorporated into regulationsgoverning total pollution loads beginning with the Fifth Total Pollutant Load Controlimplemented in 2004. Measurement by automatic measurement instrument is mandatory forfactories and other establishments whose waste liquid discharge volume is greater than 400

m3, per day.No principles or methods of measurement are specified for automatic measurementinstrument of the total nitrogen and total phosphorus under the Total Pollutant Load Control.Any measurement instrument complying with the standards for performance, control, andmaintenance set forth in the “Manual of measurement methods for water quality pollutant loadusing nitrogen/phosphorus automatic measurement instrument (published by Japan's Ministryof the Environment)” can be used.The TPNA-500 uses the ultraviolet oxidative dissolution method.

Ultraviolet oxidative dissolution method

Principle of measurement for total nitrogen

Alkaline potassium peroxodisulfate solution is added to the sample solution. Irradiation by

ultraviolet light then causes oxidative dissolution of nitrogen compounds to nitrite ions (NO3-).

Total nitrogen (TN) concentration is obtained by measuring the nitrite ion concentration usingan ultraviolet absorption photometer. The advantage of this method is the simplifiedarchitecture of the dissolution tanks that enables dissolution to be carried out under normalatmospheric pressure at a lower temperature (100C) than thermal decomposition methodsthat require 120C.

Principle of measurement for total phosphorus

Potassium peroxodisulfate solution is added to the sample solution followed by irradiation withultraviolet light, causing oxidative dissolution of phosphorus compounds to phosphoric ions

(PO43-). L-ascorbic acid solution mixed with a solution of ammonium molybdate and

potassium antimonyl tartrate are then added to the sample to bring about a chromogenicreaction forming molybdenum blue. The total phosphorus (TP) concentration is obtained bymeasuring the absorbance of the molybdenum blue at the absorption wavelength of 880 nmusing an absorption photometer. The advantage of this method is the simplified architecture ofthe dissolution tanks that enables dissolution to be carried out under normal atmosphericpressure at a lower temperature (100C) than thermal decomposition methods that require120C.

Preparation of printer

1. Open the printer door.

2. Pull the paper cover open lever of the printer to open the paper cover.

3. Set the printer paper in the indicated direction.Printing cannot be performed if the front and back sides of the paper are reversed.

4. Pull the end of the paper out of the paper discharging opening and push both endsof the paper cover, and then close the cover.

5. Press the FEED button to feed the paper and wind it around the take-up shaftseveral times.

6. Pinch the printer paper wound around the shaft with the take-up retainer to secure it.

NotePeriodically check the remaining amount of printer paper while taking the printing mode setting of theprinter (printer paper consumption) into consideration.If the remaining amount of printer paper is insufficient, it is recommended that you replace it ahead oftime. If the printer runs out of paper, printing cannot be performed.

The printer paper for the TPNA-500 is a highly sensitive thermal paper for high-speed printers.For purchase of the printer paper, specify the parts code listed in “ Accessories andconsumables” (page 229).

Note the following when storing the printer paper after printing. Store it in a dark place with no direct sunlight (temperature: below 40C, humidity: below 80%). If the printer paper is put in a flexible polyvinyl chloride case, the color of the area in

contact with the case will fade. Use a polyethylene or polypropylene bag. Rubber adhesive and any types of adhesive containing organic solvent will discolor the

paper. Do not use such adhesive for attaching the paper to other papers. Bringing the paper in contact with erasers or adhesive tape will discolor the paper. Rubbing the paper surface hard may discolor the paper. Thermal paper is not suitable for long-term storage. If the material is to be stored in the long term,

it is recommended that you make a copy of it on a copy machine and store the copied paper.

Operation

48

For initial operation

When you operate the equipment without performing calibration, the measurement values arecalculated according to the calibration data obtained at the factory.As the calibration values vary depending on the installation environment, the correct valuesmay not be displayed.It is recommended that you perform calibration before measurement.

NoteCheck that the meter is installed correctly.For installation, refer to the attached Installation Work Procedure.

According to the total pollutant load control enacted by Japan's Ministry of the Environment forfactories that discharge waste liquid to the closed water area, if there is no correlation amongthe measurement values obtained by the automatic total nitrogen/phosphorus monitoringsystem, manual analysis defined by 45 and 46 for JIS K0102 (measurement value obtained bythe specified measurement method), and the TPNA-500, the following conversion formulashould be used.The conversion formula is expressed as follows:

y = a + bxHere, the variables x and y represent the following:

x: Measurement value obtained by the automatic total nitrogen/phosphorus monitoringsystem

y: EquivalentThe value of “y” is regarded as the TP/TN value obtained by the specified measurementmethod.

Reference

For details on how to input coefficients a and b, refer to “ CONV. COEF. SET” (page 77).

Maintenance

191


It is necessary to perform the waste liquid processing before the waste liquid tank becomesfull of waste liquid. Check the liquid level periodically and perform waste liquid processing.


Note When you perform maintenance, be sure to stop the measurement, and then turn the

maintenance switch ON. The measurement waste liquid is highly acidic, and it contains heavy-metal ions. Perform the

appropriate waste liquid processing. Be extremely careful so that the waste liquid does not overflow from the waste liquid tank.

In the standard specification, approximately 24 L of waste liquid is drained per measurement.When measurement is performed hourly, approximately 0.6 L of waste liquid is drained per day.The capacity of the standard waste liquid tank is 20 L (approximately 30 days when measurementis performed hourly).

When the tank becomes full of waste liquid, a “Full Drain Tank” alarm will be output and themeasurement will be stopped.

The waste liquid contains acids and alkalis. Therefore, it must be disposed of according to therelated laws and/or regulations on the treatment of waste. Perform the waste liquid processingaccording to the related laws and local regulations.

Target Waste liquid tank

Procedure Waste liquid processing

Cycle/timing (guide) Once a month or before the tank becomes full of waste liquid

WARNING

Beware of waste liquidThe waste liquid contains acid, alkali, and heavy metals. When you handle the waste liquid, be sure to wear protective gloves and goggles so that you will not come in direct contact with the waste liquid.If it gets on your skin or in your eyes, rinse it off with a plenty of water immediately and contact your doctor.If you swallow it accidentally, contact your doctor immediately.

Maintenance

Replacing the reagent bottle

If only insufficient reagent remains, measurement cannot be performed correctly. In order toavoid this, periodically check the remaining amount. If necessary, replace the reagent bottlewith a new one.

Note When you perform maintenance, be sure to stop the measurement, and then turn the

maintenance switch ON. The reagent deteriorates differently depending on the storage environment before use and the

usage environment. Therefore, the replacement cycle indicated above should only be used as aguide.

The reagent deteriorates differently depending on the storage temperature. Store the reagentbefore use in a cool and dark place (guide: 15C or less). When you receive a reagent, use it assoon as possible.

Inspection

Check the remaining amount of each reagent.If only insufficient reagent remains, replace the reagent bottle with a new one as instructedbelow.

NoteIf the remaining amount of reagent is less than 1 cm from the bottom of the reagent bottle, it isnecessary to replace the reagent immediately.

Replacement

There are two types of reagent replacement method: collective replacement and individualreplacement.

Note A new reagent bottle is fully charged with reagent. If you grab the side of the bottle while the cap

is open, the reagent may spill out. When opening the cap of the reagent bottle for setting orreplacing the reagent, be careful not to spill the reagent. For example, place the bottle on a flatsurface.

Take care not to damage the reagent tray (load capacity: 5.0 kg)While the reagent tray is pulled out, do not place anything other than the reagent bottle specifiedby HORIBA Advanced Techno.

When setting or replacing the reagent, match the color of the tube connected to the nozzle unitwith that of the reagent bottle label. Then, set it in the correct location.If it is set in an incorrect location, measurement cannot be performed correctly.

Note If there is an excessive amount of suspended solids (SS) in the sample water, periodically clean

the dilution tube before the suspended solids are accumulated inside the tube. When you perform maintenance, be sure to stop the measurement, and then turn the

maintenance switch ON. Because the tip of the glass tube is thin, be extremely careful not to break it.

Inspection

Check if dirt is accumulated in the dilution tube and cell measurement tube. Also check thatthe sample water is measured and discharged appropriately.

Cleaning

1. Perform the operation below to discharge the sample water from the dilution tubeand cell measurement tube.

2. When the operation of step 1. is completed, press [POWER] and then follow theguidance to turn OFF the power.

9. Replace the PharMed tube below the dilution tube. Cut a new PharMed tube into thesame length as that of the old PharMed tube, and then insert it into the dilution tubefirmly.

NoteWhen inserting the new PharMed tube, check that the insertion section of the PharMed tube below thedilution tube is not wet.

10. Check that the O-ring at the rear of the dilution tube retaining plate is correctly set.

11. Attach the dilution tube retaining plate to the dilution tube, and then attach it to theequipment.

Note When attaching the dilution tube, do not apply excessive load, as it could bend the measurement

tube. Otherwise, measurement may not be performed correctly. When the measurement tube is bent, do not replace it with a commercially available FEP tube.

Instead, use the measurement tube designated by HORIBA Advanced Techno and cut it into thesame length as the existing tube. For purchase of the measurement tube, contact HORIBAAdvanced Techno.

Material

Measurement principle

Total nitrogen: Ultraviolet oxidative dissolution method

The drained total nitrogen compounds contain organic nitrogen compounds, nitrate, nitritesalt, and ammonium salt, when largely divided.

Principle

Add potassium persulfate and sodium hydroxide to a sample and apply ultraviolet irradiation. The

nitrogen compounds in the sample are dissolved to nitrite ions (NO3-). Add hydrochloric acid to the

dissolved sample to remove carbonate compounds, which interfere with measurements.Measure the ultraviolet absorption at the absorption wavelength of 220 nm for nitrite ion andobtain the total nitrogen.

Total nitrogen measurement flow

Features and application

The oxidation method by ultraviolet irradiation is highly efficient in oxidizing NH4 ion, which is ahardly oxidizable substance, even without increasing the temperature as with the autoclavemethod. In addition, another advantage is that the oxygen radical generated during dissolutionof potassium persulfate creates hydroxyl radical, which has strong oxidizing power.

Material

225

Total phosphorus: Ultraviolet oxidative dissolution - Molybdenum blue spectrophotometric method

The total phosphorus compounds to be drained contain organic phosphorus compounds,condensed phosphates, and other inorganic phosphates, when largely divided.The concentration of total phosphorus compounds in the drained sample can be obtained bydissolving the organics within the sample by potassium persulfate and determining thequantity of phosphoric ions in the solution.

Principle

Add potassium persulfate and sulfuric acid to a sample and apply ultraviolet irradiation. The

phosphorous compounds in the sample are dissolved to orthophosphoric acid (PO43-).

Phosphoric ion generates molybdenum blue through reaction with phosphomolybdic acid andascorbic acid under acidic conditions. Measure the absorbance of the molybdenum blue at theabsorption wavelength of 880 nm and obtain the total phosphorus concentration.

Total phosphorus measurement flow

Features and application

There are two methods to dissolve samples: autoclave method and ultraviolet oxidationmethod. With the ultraviolet oxidation method (potassium persulfate is added), sampledissolution can be performed at a lower temperature (approximately 95C) compared with thechemical analysis method, such as autoclave method.

Sequence: Measurement/span calibration

Tip The following sequence process table applies to the case in which the TP measurement range is

10 mg/L and TN measurement range is 50 mg/L. Only the processes of serial nos. 6 to 17 vary according to the TP measurement range. Only the

processes of serial nos. 34 to 45 vary according to the TN measurement range (shaded columns).Refer to the process that corresponds to the measurement range being used.

When sequence operation is performed for line 2, the process name indicates “L2”, instead of“L1”.

*1: During span calibration sequence, the process name indicated in brackets is displayed. A part of the display of “Drain Sample” in serial nos. 1, 30, 58, and 71 varies depending on the

setting conditions. For details, refer to “ Drain Sample” (page 241). The “Line Blow L1” process in serial no. 68 is not performed in the off-line mode.

TURB. COEFFICIENT SET (Option)

This section is the supplementary explanation for the turbidity compensation of the TPNA-500when TN is measured.

MEAS. LINE SETOne line is added to the original table for the turbidity compensation.

TURB. COEFFICIENT SETSelect the turbidity compensation coefficient setting.

NoteThe absorbance at 220 nm for TN measurement is influenced by turbidity, the absorbance at 270 nmwith a compensation factor is subtracted from the absorbance at 220 nm to obtain the turbidity-compensated total nitrogen.The turbidity compensation setting is not necessary to be changed under the condition that the goodcorrelation with the manual analysis is obtained.

Item Description

LINE CHANGE SET Specifies the allocation of the measurement line.

CONV. COEF. SET Specifies the conversion coefficient.

CONC. ALARM SET Specifies the TP/TN concentration alarm value.

LOAD ALARM SET Specifies the TP/TN load alarm value.

FLOW ALARM SET Specifies the flow rate alarm value.

TURB. COEFFICIENT SET Specifies the turbidity coefficient.


Coefficient L1 ～ L2 0.000 ～ 3.000 2.000 Turbidity compensation coefficient setting.

Note : L2 can be selected only for the two-point meter specification.
