Oil Film Detection

The OFD instrument uses a non-contact laser to measure the reflectance of the water surface. Very thin films of oil refract light and cause an increased reflectance. The instrument is capable of detecting sub-micron films and providing an alarm output. The instrument is an ideal pollution alarm for surface water monitoring where the runoff may be contaminated by oil ingress. Applications include monitoring runoff from international airports, bunded areas and hard-standing around large manufacturing plants. Typically the instrument is powered by a single phase mains supply however it is also possible to power the instrument using solar panels and a battery pack.

Oil Film Detection

Oil in Water measurement

Some applications require oil to be expressed as a concentration. For applications where oil is not typically present and trace level detection is required, UV-fluorescence may be a suitable methodology. The technique is particularly sensitive to PAH (polycyclic aromatic hydrocarbon) and the Enviroflu sensor is a robust, digital probe technology which may be mounted directly in to a sample stream or alternatively into a small tank receiving a pumped sample. The sensor provides measurement over the range 0-500 PPB and is therefore ideal for intake protection of drinking water treatment facilities and for applications where water purity is a consideration.

Nitrate Measurement

Nitrate measurement is an important water quality parameter used to indicate water pollution. Nitrate may be determined using on-line instrumentation.

The latest probe measurement technology uses UV spectral analysis at 212nm with various other measurement frequencies to compensate for variations in the sample matrix (turbidity and dissolved organics etc within the sample).

The probe is of robust construction and can accommodate automatic compressed air cleaning, a wiper mechanism or ultrasonic flow cell cleaning.

The probe can be used in waste water, industrial and within potable water production, monitoring applications. 

Industrial applications include surface water monitoring at fertlizer manufacturing facilities.

Water intake protection monitoring may include nitrate measurement in catchments exposed to significant agricultural surface water runoff. Waste water monitoring would include after the nitrification treatment process to measure treated water quality and to report the total nitrogen balance.

Additionally, dissolved organics (TOC, BOD, COD equivalent) and suspended solids may also be reported from the same probe (OPUS model). 

Nitrate Measurement

pH meter

The determination of pH is an important water quality parameter used throughout industry for process control and for environmental testing of water. The parameter may be continuously measured using an on-line pH meter, or by field portable or laboratory instrumentation. The pH of water is a measure of the acidity or basicity and can indicate the presence of water pollution. It may also be important to neutralise pH by controlling dosing systems before discharging effluent to a local water course or trade discharge. Monitoring pH on surface water from industrial sites with large hard standing is also an important environmental control measure.

The WTW IQ Sensor Net system accommodates multiple sensor inputs including the Sensolyt 700 IQ, allowing signal transmission over considerable distance. Similarly, the Chemitec 50 series is a digital platform accepting multiple sensor inputs including the competitively priced S401 DIG digital pH sensor. Temperature is also measured (for automatic temperature compensation) and can be independently output from either controller.

Turbidity measurement of final effluent

Turbidity is the measurement of light scatter and is typically reported as NTU nephlometric turbidity units. NTU refers to the 90° angle of measurement used for water quality measurement for drinking water applications. Turbidity measurement is also commonly used for final effluent monitoring to infer suspended solids concentrations affecting water quality. Different types of turbidity instrumentation are available for drinking water and final effluent monitoring.

The WTW Visoturb sensor is a robust submersible probe that incorporates continuous ultrasonic cleaning, 90° light scatter measurement combined with a backscatter technique used for diagnostics and the very best optical measurement window. Whilst primarily designed for waste water monitoring, digital range selection allows detection from 0.01 NTU and selection of five measurement scales to 4,000 NTU.

The Chemitec S461TN sensor is designed for waste water applications and features an optical face mounted at 45° to prevent air bubbles from adhering to the optical face. The digital sensor uses an IR light source and nephlometric 90° light scatter measurement over the different scaling range 0-4,000 NTU and can re-scaled to suit the application. The sensor is supplied pre-calibrated but the user has the possibility of performing a single or dual point calibration or alternatively expressing readings as mg/L suspended solids. Temperature is also integrated as standard. The sensor can be directly mounted in a tank or flow cell.

Water Quality Monitoring

Surface Water Measurement

Hard standing areas across the site often generate significant surface water which is typically discharged to a local water course. Finished product, waste and fuel can ingress into the site drainage system which can then affect surface water quality. Continuous water quality measurement may be used to identify pollution events and linked to control systems, to avert discharge of poor surface water quality. Instrument such as the Protoc Total Organic Carbon (TOC) analyser can be used to identify ingress of organic contamination within surface water drainage systems and control abatement systems.
