Understanding the application of dewatering filter presses in wastewater treatment is essential for effective water management. Here's a detailed overview of key concepts and practices in this field. a. **High-quality water**: This refers to water that has undergone multiple stages of purification, including coarse filtration, fine filtration, and sterilization. It is typically derived from municipal water sources and processed further to meet drinking water standards. b. **Mineral water**: Naturally occurring water containing minerals and trace elements. It undergoes minimal processing such as sterilization and filtration before being sold as a commercial beverage. c. **Purified water**: Water that has been treated using advanced filtration systems with high salt rejection rates. It contains very few impurities, with an electrical conductivity usually ranging between 1.0 to 0.1 µS/cm. d. **Molecular composition of water (H₂O)**: The molecular weight of water is approximately 18.015 g/mol. Hydrogen makes up about 11.19% of its mass, while oxygen constitutes around 88.81%. e. **Salt content in water**: Also known as mineralization, it indicates the total amount of dissolved salts in water. It reflects the concentration of various ions like sodium, chloride, calcium, and magnesium. f. **Water hardness**: This refers to the concentration of metal ions—primarily calcium and magnesium—in water. When these ions combine with other anions, they can form scale deposits. g. **Conductivity and resistance**: The purer the water, the lower its salt content, resulting in higher resistivity and lower conductivity. Ultrapure water has extremely low conductivity, nearly non-conductive. Conductivity is the reciprocal of resistance. h. **pH value**: The pH of water is a measure of its acidity or alkalinity, calculated as the negative logarithm of hydrogen ion concentration. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline. i. **Pure water**: This is water where most strong and weak electrolytes have been removed or reduced to a certain extent. Its typical conductivity ranges from 1.0 to 0.1 µS/cm, with a resistivity of 1.0 to 10.0 × 10ⶠΩ·cm. j. **Ultrapure water**: Almost entirely free of electrolytes, gases, colloids, and organic matter, including bacteria. Its conductivity is generally between 0.1 and 0.55 µS/cm, and its resistivity at 25°C is around 18.3 × 10ⶠΩ·cm.
