1.Overview

1.1Introduction

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 defined 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.

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 flash (CF) card.

1.2.2Display

This section describes the parameters shown on a typical display:

•The display is touch panel. Do not press buttons with wet hands, or a sharp object such as a pen tip or a screwdriver.

•If no buttons are pressed for a certain period of time, the backlight turns OFF.

•If no buttons are pressed for about two hours on displays other than those for measurement, data or alarm, the display turns to the measurement display.

• Example of display-Displaying measurement readings

The display shows measurement readings.

2.7Measurement 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 figure 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 difference 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.

• 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).

• 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.

IM 12K01B02-01E

<2.Specification> 2-12

• 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 specified value, the linearity deteriorates due to the scattering light influence.

• 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 valueYi (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 theY-axis segment (b) can be calculated by using the measurement value and the least-square method as in the following formula.

a=Y		- bX
										nSXiYi - (SXi)(SYi)
b=	(Xi - X)(Yi - Y)								=
											2 - (SXi )2
		S(Xi - X)2								nSXi

“a” and “b” are rounded to a value which is larger by 1 digit according to the number of significant figures of the measurement value.
