Water treatment:
One of the most important applications of Phosphonobutane tricarboxylic acid is in water purification.
Phosphonobutane tricarboxylic acid is used as an anti-corrosion and antiscalant in industrial units.
Water used in cooling systems and other industrial equipment contains hardening agents and impurities such as calcium carbonate and copper ions.
These impurities cause many problems, including sedimentation in pipes and other paths that deal with water, and also cause corrosion in the system.
Amino trimethylene phosphonic acid (ATMP) and Etidronic acid (HEDP) also have this capability, but there are two barriers to using these substances: Limitations in the solubility of their salts and their low resistance to oxidizing agents
Anticorrosion and antiscalants:
Phosphonobutane tricarboxylic acid has more power than other phosphonates as an anti-corrosion and anti-scaling agent.
Phosphonobutane tricarboxylic acid can be used to control the deposition of calcium carbonate.
In addition, Phosphonobutane tricarboxylic acid is very useful in harsh conditions and very high temperatures, and with high alkalinity.
Cooling systems and industrial water treatment units:
In systems where water plays a key role as a cooling agent, the presence of substances such as calcium ions causes deposits inside the equipment, which blocks the passage of water and makes the system inefficient.
The best way to solve this problem is to use antiscalants such as Phosphonobutane tricarboxylic acid.
Industrial detergents:
One of the most important applications of phosphates is in the production of detergents.
The use of these materials has the following advantages: reducing hardness and preventing the formation of sediment and dispersion of contaminants and controlling their deposition.
