Power generation plantsReading time:
This section addresses the two main water treatment issues within power generating plants, i.e.:
- treating the effluent produced by the sulfur and mercury removal systems and even “deNOx” (removing nitrous oxides) also known as the “ FGD wastewater treatment system”;
- water reuse treatment systems for make-up process water required for cooling, boiler make-up, etc. with the focus of conserving natural surface and ground waters (dry zones, severe environmental factors).
It should also be noted that there are specific issues as highlighted in table 68 of energy, with fuel depot water (classic oil removal), water containing fly ash (coal and lignite power plants), and boiler cleaning water. These are site-specific issues. In the case of water containing ash, for instance, the resolution will depend substantially on whether the ash is acid or alkaline.
