INTRODUCTION

52

Monitoring of quality of Surface Water

Resources.

The water quality of a stream, a watershed, or

a large river system can be enhanced only by

collecting good information about current

conditions. That information is the foundation

of actions and measures to reach or maintain

a high water quality.

• Monitoring is necessary to ensure whether protection and restoration

measures are working.

• Long-term data collection is critical to identify trends or patterns. Water

quality can constantly change— during the day, from day to day, from

season to season, and from year to year.

• Protect drinking water resources

• Monitoring of pollution accidents of rivers ( TOC, COD )

INTRODUCTION

53

Why do we need Water FLOW and LEVEL

measurement ?

The quantity of stream-flow is an important factor in determining water

quality and, thus, in interpreting water-quality data. The potential effects

of contaminants on drinking-water supplies and aquatic habitats depend

largely on the amount of water flowing in streams.

- Flood and Flash Flood: EARLY WARNINGS by SMS / e-mail.

- Measurement Stations with REAL TIME data transmission.

- Parameters are : Flow ( m³/s), Level (m), Rain (m3/m²).

- Data are available on the WEB.

- Discharge data also help with interpretation of water-quality data.

( f ex.: higher turbidity could come together with high or very high flow)

Pollution = Concentration * Quantity

INTRODUCTION

54

Continuous and automatic Water Quality

Monitoring.

• Monitoring stations continuously measure dissolved oxygen,

temperature, pH, specific conductance (TDS ; salinity), turbidity,

suspended solids, algae, NO3, NO2, NH4, PO4, TOC, COD, BOD.

• These parameters are good indicators of river water quality and the

effectiveness of upstream wastewater treatment plant (WWTP)

operations.

• Polluters can be identified by long term

24/7 measurements

• Modern Analytical Equipment is highly

sensitive. PPM / PPB

Is dilution

the solution

for pollution ?

QUALITY - CALIBRATION

WTW VisoLid 700 IQ® and

VisoTurb 700 IQ® are „ no – drift “

sensors. Optics and electronics are

designed to be extraordinary stable.

Both are factory-calibrated. A

recalibration is not required .

Sensor Signals

are immune to

ambient

light

73

Individual CAL DATA on the membrane

module make the FDO 700 IQ the only

DO sensor which needs NO

CALIBRATION.

WTW FDO 700 IQ® membrane ( optical

fluorescence measurement) is individually

factory calibrated

- those individual calibration data are

permanently stored on a memo chip, which is

inside the membrane.

- calibration data are automatically passed to

the sensor, once the membrane is mounted

- -

measurement of

DISSOLVED OXYGEN

QUALITY - CALIBRATION

74

WTW - FDO 700 IQ: Green light gets warranty

extended from 6 months to 2

years

By using GREEN excitation light, ( instead of

blue) bleaching of the fluorescent dye in the

sensor membrane is minimized. This leads to

an exceptionally long lifetime of the

membranes and low maintenance

-

QUALITY - LONG LIFE

75

Whenever a SENSOR is NOT

available we need to use an

ANALYZER

XYLEM has Analyzers for:

NH4

NO3/NO2

TOC(heated persulfate)

COD(cr)

PO4

TP

Analyzers are optimized for:

• Short measurement intervals

• Low reagent consumption

• Low maintenance

• Automatic calibration

ANALYZER – Continuous Analysis in River Monitoring Stations

76

TOC ONLINE with:

9210 p Analyzer heated persulfate oxidation

will oxidize it all, for most

accurate results and regulatory

compliance.

ANALYZER - TOC

In 40 CFR 133.104 the U.S.

EPA allows to substitute TOC

analysis for BOD5 monitoring,

when a long-term correlation

has been demonstrated. Gains

in precision, economy,

efficiency and accuracy are

associated with TOC

measurement.

77

The OI TOC analyzer

9210 P

continuously monitors

the sample stream,

determines, and reports

the TOC concentration.

It output signals are

sent to a data logger for

continuous storage of

TOC data

Set alarms for high TOC

levels are detected and

SMS alarm messages

are instantly created

ANALYZER – Ammonium – Nitrate - Phosphate

79

WTW Phosphate Analyzer

P 700 IQ is based on the

photometric ”yellow”

method ( Molybdate-

vanadate). It can be

mounted outdoor and is

famous for an extremely

low reagent consumption.

Phosphorus compounds

are considered to be the

limiting nutrients in most

waters. An increase in their

concentration results

directly in increasing

eutrophication of the water

How does a “MONITORING STATION” look

like ? DEPENDS:

WHERE to measure? On a river bank ? In the middle of a reservoir?

Under a bridge ? On a boat ? On a van ?

WHAT PARAMETER to measure ? Some, such as turbidity or DO can be

better measured directly in the river, flow and level have to be. For

others, pumping water into a cabinet might be better.

Do we need to PROTECT the equipment against theft and vandalism ?

Do we need POWER SUPPLY, or do we have mains connection ?

Do we need WIRELESS DATA TRANSMISSION ( GSM, Radio, Satellite) ?

DESIGN of a MONITORING STATION

81


Parts of a Monitoring

Station ? Sensor “platforms”: Buoys, Pontoons,

Trailers /Vans, Houses,Boxes, …

Components: Datalogger; Solar panels,

Batteries, Regulators, Junctions,

Connectors, Antenna, Modems.

Data transmission:Satellite, DAA,

Iridium, GOES, GSM, GPRS, 3G, 4G,

Radio.

Data procession: Data on Web,

Smartphone, Intranet.

82

An automatic monitoring site may consist of

a land-based, lockable box, where river water

is continuously pumped into.

A pump as well as mains

power and a concrete

foundation are needed.

A fence can protect from

vandalism.


83

An automatic monitoring site may also be a

lot bigger; a shelter, a container, even a

house may be used, … or a van:


84


If the only water measurement parameter is

the LEVEL, the monitoring station can be

very small:

The level sensor is directly

immersed. Data collection (logger)

and wireless transmission is

included. Powered by solar or

battery. Level sensors can be

hydrostatic, sonar, radar.
