Using treated municipal wastewater for Power Plant make-up is more sustainable than using surface or underground water.
This water requires a pre-treatment technology to remove residual organics (measured as Biochemical Oxygen Demand or BOD), ammonia, and pathogens.
Biological rather than physical-chemical treatment offers great benefits. Fresh water is preserved for other uses, and there is reduction in chlorine for breakpoint chlorination to remove ammonia.
Reclaiming municipal wastewater effluent as a source of make-up water benefits the power company, the municipality, and the environment. AnoxKaldnes have references and experience to guide your investment towards a “Win-Win-Win`solution for all entities:
Benefits to Power Companies:
- A guaranteed source of Water (drought-free)
- Improve efficiency and footprint of the power plant by using water-cooled vs. air-cooled condensers
- Quicken the permit process to build a new plant since a request for a large volume of fresh water is not needed
- Increase Corporate Social Responsibility (CSR)
- Sewage plant effluent is more consistent than changing river water; making the treatment processes easier to operate
Benefits to the Environment:
- Reduction in freshwater use – leaving it for drinking and agriculture
- Large volume of sewage plant effluent is treated and not discharged to the environment
Benefits to Municipalities:
- Potential ability to reduce costs if discharge loadings or discharge flows are taxed
