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

Microtol Turbidity instrument designed for turbidity measurement within water production processes

The HF microtol turbidity instrument is a nephlometric analyser suitable for continuous water quality measurement of the potable water process

No Image

The microtol instrument is distributed in the UK by PPM and is an establish nephlometer used within water production to monitor the raw, filter and final water quality.

The instrument is available covering the measuring ranges 0-10.00; 0-100 and 0-1,000 NTU.

The simple, compact design is very easy to operate and maintain using a pressurised flow cell to reduce the effect of entrained air. An additional bubble rejecion system can be fitted but is not typically required.

Calibration is very simple. Stable primary standards can be inserted to complete a three point calibration. A single set can be used on multiple instruments and are valid for one year. 

The integral tactile keypad allow for simple operator interaction. Continuous ultrasonic cleaning is available on some models to minimise fouling on raw water.

Water consumption is low. Installation is very simple and space requirement is minimal. The microtol is a very competitive instrument with low running costs.

This is why it is very popular with many installations within Affinity Water and Welsh Water.
