For the purchase of commonly used valves for water treatment, look for a water system valve supplier with a two-year warranty—Bundor Valve.
Water treatment is the abbreviation for water supply treatment and wastewater treatment, and it is an important part of water industry science and technology.
Classification of water treatment methods
Generally divided into primary processing, secondary processing and tertiary processing (advanced processing, advanced processing).
Primary treatment is mainly pretreatment. Physical methods or simple chemical methods (such as preliminary neutralization of pH) are used to remove suspended solids, colloids, suspended oils and other pollutants in wastewater. The treatment level of the primary treatment is low, and generally does not meet the specified emission requirements, and the secondary treatment is still required.
The secondary treatment is mainly to clear the colloidal or dissolved organic pollutants that can be decomposed or oxidized, and more economical biochemical treatment methods are used. After the secondary treatment, the wastewater can generally meet the discharge standards, but there may be residual microorganisms, non-degradable organic matter, and inorganic salts such as nitrogen and phosphorus. They are not large in number and usually do not cause much harm to the water body.
Three-level governance is also called in-depth governance, and it is only used when there are special requirements. It is the secondary treatment of wastewater, and then use physical and chemical technology for further treatment, in order to remove soluble inorganic matter and indecomposable organic matter, remove various viruses, germs, phosphorus, nitrogen and other substances, and finally reach the surface water , Industrial water or water quality standards close to domestic water.
Aerobic activated sludge method, biofilm method, anaerobic digester method, etc.
Commonly used valves for water treatment
1. Cut off valve
Mainly used to cut off or connect the medium flow. Including gate valves, globe valves, diaphragm valves, ball valves, plug valves, butterfly valves, plunger valves, instrument needle valves, etc.
2. Regulating valve
Mainly used to adjust the flow and pressure of the medium. Including regulating valve, throttle valve, pressure reducing valve, etc.
3. Check valve
Used to prevent the medium from flowing back. Includes check valves of various structures.
4. Shunt valve
Used to separate, distribute or mix media. Including various structures of distribution valves and traps, etc.
5. Safety valve
Used for safety protection when the medium is overpressured. Including various types of safety valves.
