Boilers are used in power plants to generate steam which is in turn used to generate power
The water supplied to the boiler is called boiler feed water. Effluent water from power plants and its treatment is strictly controlled by national and international laws.
Wastewater may only be discharged after prior de-oiling with specially approved treatment systems. The maximum oil content must not exceed 15 ppm. However, the limit has even been reduced to 10 ppm in some areas. Swan Analytical & Uniper UK Ltd worked with Rivertrace to introduce an oil in water discharge monitoring system with additional pH and temperature monitoring for the Isle of Grain Power Station in the UK to ensure the plant’s continued compliance with local and international regulations to ensure proper functioning of the boiler systems.
