The boiler make-up water is mainly used to supplement the steam loss of the water vapor system; the make-up water treatment can be divided into water pretreatment and desalination treatment according to the treatment process; the source of the make-up water is currently mainly natural water bodies in China, such as rivers, reservoirs, lakes and For groundwater, some power plants use tap water as raw water. As the hydrological conditions vary greatly from place to place. Water quality varies. Therefore, the process flow used is also different.

SP Solution:

In the application of pre-demineralization treatment system, the main purpose of water pretreatment is to remove silt, clay, humus and colloidal particles in the raw water. Reduce the turbidity to 15mg/L. When the raw water has a high salt content, in order to reduce the burden of the ion exchange device, electrodialysis or reverse osmosis pre-demineralization treatment is used, and membrane separation technology is often used.

SP Advantages:

ØThere is no need to add coagulant, which can remove a wide range of pollutants

ØVarious filter materials, including cellulose acetate membrane, aromatic polyamide membrane, polysulfone membrane, polypropylene membrane, inorganic ceramic membrane, etc.;

ØHigh precision. Membrane filtration is divided into four types: microfiltration, ultrafiltration, nanofiltration and reverse osmosis according to the membrane pore size from large to small;

ØIt has a wide range of applications, choosing different membranes to achieve the predetermined separation effect on particles in a broad sense such as ions, molecules, viruses, bacteria, clay, and sand; reliable operation, compact equipment, easy to achieve automatic control, etc.
