Parallel to the greater demand for drinking water quality (e.g. as defined in the EU drinking water directive) there is also a growing interest in particle measuring technology. Particles, namely suspended solids, are undesirable in drinking water for hygienic reasons: they may be pathogens or other unwanted microorganisms, or organisms may be attached to or enclosed in particles. Further, particles can reduce the effectiveness of disinfection substances. The aim of water treatment is therefore to produce drinking water that is as low as possible in particle content.

Particle content is normally monitored by measuring turbidity; this measurement provides a summary statement about the total particle content. In some cases, for example in membrane filter systems, or generally for enhanced water quality security, an additional measurement of the particle concentration in the range of 1 to 5 micrometers may be advisable.

Thus SIGRIST has now expanded its range of turbidity measurement instruments for drinking water treatment with two particle counters that are specifically designed to meet the requirements for water treatment. The OPM32 has 32 size channels, a data logging function, PC software and an integrated sampling pump, all of which make it a high-quality instrument for laboratory measurements, process optimization, and detailed examination of filtration processes. The OPM3 offers 3 size channels, 4..20 mA current output, and hydrostatic sampling feed control without wearing parts – it is the ideal solution for the continuous monitoring of filter systems. Both instruments measure particles from 0.9 micrometers and upwards and have proven their effectiveness in various installations.
