Pollution & Process Monitoring Ltd
PPM is an independent limited company which manufactures and distributes instrumentation for water and waste water applications. The company was founded in 1990 by a small team of highly qualified engineers that pioneered on-line TOC – Total Organic Carbon monitoring. Subsequently, analytical measurement technology for the on-line determination of Ammonia and Chloride were developed, in addition to laser technology, providing detection of floating oil films.
The company has expanded over the years and now represents a number of international companies manufacturing complementary technologies.
To support our analytical installations, PPM can schedule reagent supply to ensure continuity of on-line water quality measurement.
We also can provide service support contracts to perform routine maintenance and emergency call out cover.
To ensure the water quality monitoring systems we provide are fit for purpose, the initial site appraisal and the commissioning and training services we provide are integral to PPM delivering robust measurement solutions.
Although the UK is still the most significant market place, PPM is progressively supporting international projects supplied through UK specification and local distribution. Representation is established for the majority of mainland Europe, USA and Asia including India and China.

Manufactured Products
PPM is accredited to ISO 9001:2015 and manufactures a range of on-line TOC analysers called PROTOC
with installations throughout industry.
The Protoc 300 version has been certified to meet the requirements of MCERTS which includes an external audit of our manufacturing processes associated with the production of this instrument. The ProAm ammonia monitor was launched in 2003 for the continuous measurement of ammoniacal-nitrogen and has been widely installed for both waste water compliance monitoring and intake protection of drinking water production. The instrument has also been adapted for chloride measurement. The OFD1 has also been developed to provide non-contact detection of floating oil films with installations in the power industry, at engineering plants measuring surface water and at drinking water intakes.
System Integration
PPM specialises in the integration of instrumentation, building pre-assembled wallboards and walk-in analyser kiosks. Small secondary enclosures and towable trailers can also be accommodated. Duty and standby pumping systems, sample preparation, data transfer, collection and display can all be provided by single company. Solar and battery powered probe measurement systems with optional GSM data transfer can accommodate monitoring applications where power supply is not available.
Distributed Products
Instruments for the on-line and discrete measurement of a diverse range of parameters are also distributed. Determinants cover nutrient analysis (N,P,K) as well physical and chemical properties such as turbidity, pH, DO and Oil. Field portable devices are also available to support on-line instruments.
