<1. Overview>

1. Overview

1.1 Introduction

GENERAL

Water pollution control laws and regulations require monitoring of wastewater quality to prevent

water pollution in lakes, rivers and enclosed bodies of water. Pollutant load is an index of water quality standards and is dened as the product of the COD (chemical oxygen demand)

concentration and the wastewater volume. Certain entities are required to measure pollutant loads and comply with the limits.

Among various methods for COD measurement, automatic ultraviolet absorption spectrometry is the ideal choice on the whole since it provides high correlation between analyzer and laboratory results, measurement continuity and maintainability.

The UV700G Ultraviolet (UV) analyzer is an instrument for continuous on-line measurement

using the same cell length modulation method as its predecessor UV400G.

It provides improved operability through a wide measuring range and touch screen interface, high

reliability and excellent maintainability.

1-1

FEATURES

• Graphic LCD with touch screen on the converter provides easy interactive operation.

• Detector uses the rotary cell length modulation method. Zero check is performed at the time

of minimum cell length, virtually eliminating zero drift.

• Continuous cell cleaning with unique wiper system, allowing long term, stable

measurement.

• Analyzer covers a wide measuring range:

from 0-0.1 Abs to 0-5.0 Abs.

• Flow-through cell type for easy maintenance.

• Data memory function for transferring data to a PC via an optional compact ash (CF) card.

2.7 Measurement Principle

The rotary cell length modulation method, which combines high performance and reliability, is

adopted in this unit.

Two cylinder cells are placed, arranged with the light source and detector in a position where they are decentered from the center of cylinder as shown in the gure below. By rotating these two cylinder cells with the centers of the light source and detector as the rotation center, the distance between the 2 cylinders (cell length) is modulated continuously and periodically. The signal input to the detector from the light source is the signal which changes the di󰀨erence in light intensity between the maximum cell length (θ = 180 degrees) and the minimum cell length (θ = 0 degree)

into the amplitude. Wide range measurement becomes possible by selecting the optimum cell length and calculating according to the change of cell length.

l Optical compensation

Optical compensation is attained by the rotary cell length modulation method. Information

required for optical compensation is the change of light intensity due to the light source, detector,

contamination of the measuring cell etc. This change in light intensity information can be obtained

by monitoring the light intensity when at the minimum cell length (θ = 0 degree).

l Turbidity compensation (TURB)

This unit can measure ultraviolet (UV) and visible light (VIS) absorbances independently. UVαVIS display is possible by setting the turbidity correction factor (α), thus a more reliable turbidity

compensation can be performed.

l TURB (turbidity) Measurement

TURB measurement is performed by using the visible light (VIS) absorbance.

The measurement method is the transmitting absorption method.

Calibration with the standard solution enables a simple measurement of TURB.

Measure in the measurement range of 200 deg. or below. If measuring in a measurement range

that exceeds the specied value, the linearity deteriorates due to the scattering light inuence.

l HowtoCalculatetheCODConversionFactor

If it is judged that there is obviously a linear function between the measurement concentration Xi (i = 1, 2, ...n) and corresponding manual analysis value Yi (i = 1, 2, ...n), the calibration curve formula (regression formula) is expressed as follows:

Y = a + bX

The gradient of this regression line X-axis (b) and the Y-axis segment (b) can be calculated by

using the measurement value and the least-square method as in the following formula.

2-12

“a” and “b” are rounded to a value which is larger by 1 digit according to the number of signicant gures of the measurement value.

5.2 Notes regarding Calibration

• Perform the calibration in the order of “Common zero calibration,” “Common span calibration,” and “TURB Span calibration.”

• If the calibration coe󰀩cient exceeds the specied range during the calibration, an error

occurs and the calibration value is not updated. The previous calibration value remains.

• Use distilled water for the common zero calibration solution. If a solution other than distilled water is used, the measurement error becomes larger in the low concentration range (0.1 Abs to 0.5 Abs).

If the ion-exchanged water is used, the measurement error also becomes larger.

• Whenever diluting the span calibration solution, make sure to dilute by adding distilled

water.

• When disposing of the common span calibration solution, follow the rules and regulations in your country / area. As the solution is colored, we recommend disposing of it by diluting with tap water unless otherwise specied.

• Store the common span calibration solution ampoule in a dark and cold place.

• Use the common span calibration solution ampoule immediately after opening.

• Never ingest the common span calibration solution ampoule or its contents.

• If the common span calibration solution comes into contact with clothes, the clothes may be

stained.

• Never reuse the calibration solution. If the solution is altered, an accurate calibration may

not be obtained.

• Prepare the span calibration solution by following the description in this manual.

5.4.1 How to Prepare Calibration Solution

Use distilled water for the zero calibration solution, and exclusive calibration solution for the

common span calibration solution.

The calibration solution ampoule (H calibration solution (blue label)) for 1 Abs (100 m-1) is attached to this unit. An attached calibration solution ampoule covers the measurement range up to 1 Abs. Full scale can be covered from 0.1 Abs to 5.0 Abs (10 m-1 to

500 m-1) by using the 2 or 4 calibration solution ampoules.

Select the measurement full scale you use from the following, and compound the calibration

solution.
