“…To begin with, ED's ability to remove pollutants is restricted. Because they are not driven to the membranes, pollutants with weak or nonexistent charge density, such as some organics, pyrogens, and elemental metals, cannot be removed by ED [21][22][23][24][25]. Second, ED necessitates the use of a professional operator as well as frequent protection.…”

Water quality has long been an important part of the operation of nuclear power plants. Water is used as a working and cooling fluid in power plants. The quality of source waters to be used in the power plants after treatment should conform to the prescribed values of Physicochemical properties like pH, EC, TDS, alkalinity, hardness, presence of chloride content, silica, and heavy metals as recommended by technical guidelines. The Physicochemical properties of water must be recovered the recommended values of the World Health Organization (WHO), United States of Public Health (USPH), and power plant water chemistry guidelines. But the values of raw water are very far from the recommended values of Nuclear Power Plants operation. So, it needs to treat to use in the boilers. Gravitation, Carbon filtration, Ion exchange method, and Reverse Osmosis (RO) are good ways to treat the water before use in power plants. The aim of this chapter is to explore the water chemistry of the source water quality parameters values and those of the recommended values of technical guidelines.

“…The DM plant refers the TH to 00 ppm for power generation. The Standard values of Total Hardness of drinking water quality in Bangladesh, the World Health Organization (WHO), and the United States Public Health (USPH) are 250, 500, and 500 ppm, respectively [27][28]. However, certain ranges can be delineated, and these are shown in Table 2.…”

Water quality has long been an important part of the operation of nuclear and thermal power plants. Water is used as a working and cooling fluid in power plants. The quality of source water to be used in the power plants after treatment should conform to the prescribed values of Physico-Chemical properties like pH, EC, TDS, Alkalinity, Hardness, presence of Chloride content, Silica, and Heavy metals as recommended by technical guidelines. To analyze the water characteristics, water samples were collected from various sources. Two river water samples and a groundwater sample (marked as PP1, PP2, and NPP site) were tested to determine the water properties. The Physico-chemical properties of the water samples were determined using various analytical tests. Heavy metals were also investigated using the Atomic Absorption Spectrophotometric (AAS) process. The Physico-chemical properties of investigated samples were so good as to the recommended values of the World Health Organization (WHO), United States of Public Health (USPH), and Bangladesh Environmental Department. But the values were very far from the recommended values for thermal power plants operation. So, it needs to treat to use in the boilers. Gravitation, Carbon filtration, Ion exchange method, and Reverse Osmosis (RO) are good ways to treat the water before use in power plants. The Padma River water is better than the other two samples when the Physico-chemical characteristics of the sample waters were analyzed to the prescribed levels for the boiler water of a thermal power plant and the secondary water circuit of a third-generation nuclear PWR reactor. The aim of this work is to explore the difference between the source water quality parameters values and those of the recommended values of technical guidelines. To minimize the water treatment cost, a new site for the installation of a power plant project in Bangladesh can be advocated depending on the availability of good quality water.
