For centuries, water was considered a commodity product and used with little or no restriction. In today’s modern society, water is now being considered a precious resource and considerable effort is put into protecting, recycling, and restricting its use freely. The same volume of fresh water is used by the irrigation industry. Certainly, whenever conforming to USGS that power plants in withdraw that is used for plant cooling cycle. Eventually, the water withdrawn by power plants adversely impacts the aquatic life, migratory and the endangered fish species. Whenever using the more efficient cooling system, Despite the new additional power generation due to increase in population and industrial growth, studies conducted by DOE indicates the withdrawal of fresh water by power generation industry will remain just like I know it’s today since the old plants continue to be replaced with new ones. New guidelines imposed by the Clean Water Act section 316 further limits the withdrawal of water for cooling and restricts the use of Once Through Cooling for many new power stations.
As well as, Undoubtedly it’s also predicted by USGS other land and water management agencies that the consumption of fresh water in the will increase by 3050″ by the year 2030 due to population growth and additional water needed by the irrigation industries.
Currently, for once through cooling system, 2050 water gallons are typically required to generate any ‘Kwhr’ of electricity.
Considering the increase in demand for fresh water there gonna be additional pressure on power generation market to further reduce its fresh water consumption and attempt to locate other alternative sources of water for use. Considering the continuing pressure by State and Federal agencies to reduce water intake by thermo electric power stations, the use of cooling tower or cooling ponds may become increasingly attractive. Of course, treated municipal waste water generated by Publically Owed Treatment Works is commonly available and is widespread across the According to Department of Energy, 81percentage of the newly proposed power plants for construction reported by the Energy Information Administration have enough cooling water supply from 1 or 2 POTW within a 10 mile radius.
Other water sources are required in case you want to be considered, as the use of fresh water or seawater for cooling tower make up water becomes restrictive or unavailable.
One potential alternative for cooling is the use of treated municipal waste water as the source for makeup water.
The availability of water is improved to 97 if the radius is extended to 25 miles from the proposed plant location. Only a small number of plants in FL, TX, CA and a few other states have used reclaimed water for make up water. That said, the presence of Phosphorus, ‘ammonia nitrogen’, and identical dissolved salts contribute to scaling and corrosion of the equipment within the cooling water circuit, including the condensers and heat exchangers. Studies and pilot testing sponsored by Department of Energy, National Energy Technology Laboratory and the work conducted by University of Pittsburg, indicates that secondary treated municipal waste water can be a reliable source of cooling water makeup, that is widely available. Which result in biofouling within the cooling system, Since the water contains high nutrients content, it allows the formation and growth of slim, algae, bacteria and identical living organisms. I know that the interest in using this water source is growing and a larger number of plants are looking at this alternative.
In might be required and it may still remain cost effective, given the scarcity of fresh water for cooling in any application the foregoing treatment technologies need to be considered and the most effective solution needs to be selected.
