Pollution & Process Monitoring Ltd


Manufacture of on-line analysers suitable for measurement of water and waste-water. We manufacture analysers reporting parameters which include TOC (Total Organic Carbon), Ammonia (ammoniacal-nitrogen) and oil film detection. UK representative for WTW, DKK & HF Scientific, 3S, Realtech and Chemitec. The instrumentation covers single and multiple parameter measurement, on-line and field portable meters. Parameters include turbidity, MLSS, ammonium, phosphate, nitrate, pH, D0, conductivity, Oil on water, oil in water, UV absorption and UVT (UV transmission). We also specialise in providing turn key monitoring solutions for water and waste water analysis. These systems include back-panels, secondary enclosures and walk-in analyser kiosks (pre-installation of instrumentation, sample preparation, frost protection, lighting, electrical and sample distribution). Installations are supported by our team of service engineers providing technical support, routine and emergency call-out cover and chemical supply. - Waste water monitoring - Water measurement - Analytical measurement - Water quality instrumentation - TOC analyser - COD analysis - BOD analysis - Ammonia analyser - Nitrate analyser - Phosphate analyser - pH meter - Turbidity meter - DO meter - Conductivity meter - ORP meter - UV254nm measurement - Oil detection - Bes

Realtech M3000 on-line % UVT analyser

The Realtech M3000 on line UVT instrument continually reports the %UVT so the UV sterilisation process may be automatically controlled.

Realtech instruments are installed to control the UV sterilisation process to ensure the correct intensity of UV sterilisation is achieved according to strict regulations.

The % transmission is affected by the amount of chemical contamination in particular organic species and the amount of suspended solids within the sample.

The analogue output (4-20mA signal) from the M3000 instrument may be connected to a PLC to control the intensity of UV light used to treat and sterilise potable water. The instrument is provided in a surface mount enclosure proving ingress protection to IP65 and integrates a local display with tactile keypad.

The instrument compares two seperate absorption measurements using a 10 and 20mm pathlength (at 254nm wavelength) which minimises the effect of calibration drift and the effect of cuvette fouling, should it occur.

Automatic acid cleaning is available as a cost option to removing fouling and reduce manual intervention.

Realtech also manufacture a portable P200 instrument which can be used to verfiy the on-line analyser and calibrate if necesssary.
