With the accelerated pace of industrialization and urbanization, water pollution phenomenon has become increasingly important, and a lot of pollution of waters not only brought great impact on people's daily lives, but also brought serious damage to the production plant. Surface water and groundwater is the main source of chemical water treatment plant, contaminated surface water, groundwater contains various magazines, harmful substances, serious corrosion of equipment, to lay the foundation for the separation technology of chemical water treatment plant in the whole film.
Full membrane separation technology, is the choice of using a membrane permeability characteristics, a thin film as a medium, as a driving force to a certain pressure, in liquid different size, a method of leaving the composition to different points of particles. Particles of different membrane pore size determined by the particle and can not only satisfy the pore size requirements to pass the film, thus achieving the separation and purification of the liquid.
Thus, a full power plant water treatment chemical membrane separation technology is one, the chemical treatment has been applied to most plants. Application of chemical water treatment plant in the whole membrane separation technique, the entire process does not require the use of any auxiliary chemicals, but in three layers separated by membrane filtration membrane process to achieve purification of the water into the raw water quality achieved in line with a relevant national water quality standards requirements.
The membrane pore size, the whole film membrane separation technology is divided into a reverse osmosis membrane, ultrafiltration membrane and microfiltration membrane, the membrane pore size and molecular separation and interception decision-retaining, each component may be completely separated, sufficiently using a selective membrane permeability characteristics, greatly enhance the treatment effect.
