In principle several fundamentally different techniques are available; non-contact detection and flow-through measurement or probe measurement. Applications include intake protection of drinking water treatment plants, monitoring of turbine cooling water discharge and surface water monitoring from large hard standing areas subject to traffic (engineering plants and international airports).

Oil on Water
Oil on water instrumentation is a reliable means of detecting floating oil films which are an indication of water pollution. Trace level contamination at sub-micron thickness can be detected using a non-contact laser methodology. Oil film measurement detects an increase in reflected light without any fouling affect on the instrumentation. Oil on water measurement is an important parameter for water intake protection and for effluent monitoring to identify water pollution. Two different models have been offered to cover different installation requirements.
Oil in Water
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.
