Sodium Aluminate for Water Treatment

During the operation of industrial production devices, the silicon compounds are prone to form silicon scale. The Sodium Metaaluminate for Water Treatment is an efficient, stable, economical and practical desilication agent. Meanwhile, it can also play a role of defluorination, desilication, dechlorination and sulfate radical removal, and be used for wastewater desilication of white carbon black.

1. Influences of silicon scale

When the pressure of industrial production process device suddenly drops, the substances such as silicates are most likely to deposit and form scaling. During the operation of reverse osmosis and evaporators in sewage advanced treatment device and saline wastewater treatment device, the silicon scale often blocks the reverse osmosis membrane, evaporator heat exchanger, falling film tube, etc., resulting in continuous decrease in the water treatment volume. The long cycle operation causes the reverse osmosis membrane to be affected by silicon scale, thus the chemical cleaning frequency is increased, the desalination rate of the reverse osmosis membrane is reduced, the service cycle is decreased, and the membrane replacement frequency is increased. The evaporator heat exchanger and falling film tube are affected by silicon scale, and on average the high-pressure cleaning and chemical cleaning are required every half year to solve the problem of insufficient water treatment volume.

2. Process of desilication with Sodium Metaaluminate for Water Treatment

The Sodium Metaaluminate for Water Treatment has very good removal effects on silicon scale. It is suggested to control the mass dosage ratio of Sodium Metaaluminate for Water Treatment and silicon dioxide in the engineering application process at 2:1. Under this condition, not only the good desilication effects can be achieved, but also a large quantity of aluminium ion residues can be avoided effectively.

3. Advantages of Sodium Metaaluminate for Water Treatment in desilication

The desilication with Sodium Metaaluminate for Water Treatment has the advantages of good desilication effects, less sludge, simple operation, and economical applicability when compared to traditional magnesium agent desilication method. It is applicable for desilication in municipal, industrial and other wastewater.
