Measurement of the pollutants that are released into the environment is important from the perspective of both prevention and treatment. Furthermore industrial processes that are more efficient tend to be less polluting or wasteful. Nuclear Magnetic Resonance (NMR) provides a fast measurement of FOG (Fat, Oil and Grease) in waste water released from both domestic and industrial premises. NMR is also used to measure fluorine during industrial processes, e.g. aluminium smelting, in order to maximise yield whilst also minimising the emission of toxic fluoride gases. More generally, NMR provides measurements for quality assurance which ensures that waste product, and as a consequence energy use, is minimised.
