This post was last edited by dongjiang1001 on 2011-6-17 at 17:30. A new leader organized an exam today. There are a few noun explanations for which I don’t know how to answer; I hope everyone can help. Thank you! RO product water, RO desalination rate, colloidal substances, coagulants, boiler water
RO produced water: Water that is obtained through reverse osmosis membranes under high pressure, by causing the solvents in the raw water to diffuse from a high concentration to a low concentration, thereby achieving separation, purification, concentration, and other processes, is known as RO produced water. RO desalination rate: It refers to the percentage of the original amount of ions that are removed from water through the reverse osmosis process. Colloidal substances: Colloidal substances refer to particles with diameters ranging from 0.0001 to 0.000001 mm (too small to be seen with the naked eye), and they are aggregates of many molecules and ions. Flocculant: A polymer that enables fine solid particles dispersed in a liquid to form flocs. Boiler water: refers to the water or water-vapor mixture that circulates between the boiler drum systems. (This is really hard to define; try to understand it better.)
