Application scenarios in the coal industry

Coal washing wastewater, coal slurry water from coal preparation plants, and ground washing wastewater from coal-fired power plants are all mixtures of water and fine coal powder. Their main characteristics are high turbidity, fine particle size of solid matter, and the surface of solid particles often carries negative charges. The repulsive force between isotropic charges keeps these particles in a dispersed state in water, which is affected by gravity and Brownian motion; Due to the interaction between solid particle interfaces in coal slurry water, the properties of coal washing wastewater are quite complex, not only possessing the properties of suspension, but also colloidal properties. In order to quickly precipitate coal slurry water in the concentration tank, ensure qualified washing water and filter coal slurry production, and ensure efficient and economic operation of production, it is necessary to choose appropriate polyacrylamide flocculants to strengthen the treatment of coal slurry water. The series of polymer flocculants developed by polyacrylamide for coal slurry dewatering in coal washing plants have high dewatering efficiency and are easy to use.
