Summary

SFS series double chamber floating bed ion exchanger adopts advanced technology at home and abroad, which has the characteristics of good exchange effect, long regeneration cycle, high effluent quality and simple operation, and is widely used in water treatment fields such as water softening and desalination, high-purity water preparation, etc. Due to the complementarity of filling strong and weak resins in the upper and lower chambers respectively, the product has the advantages of single chamber floating bed, good effluent quality (< μ s / cm3), less specific consumption of regenerant, acid consumption only 1.05-1.1 times of the theoretical consumption, alkali consumption only 1.1-1.2 times of the theoretical consumption, less self consumption, and waste water neutralization consumption.

working principle

Upflow water

The treated water penetrates the resin layer from the bottom to the top and boils in two chambers. The resin in the upper and lower chambers of the floating bed forms a boiling layer and a floating layer (pressing layer) according to a certain proportion, and a water cushion is formed between the boiling layer and the floating layer to strictly separate the two. The ions in the treated water are firstly exchanged with the resin in boiling state, increasing the exchange contact surface, giving full play to the exchange capacity of the resin. Most of the ions can be removed by the resin exchange in boiling state, and the remaining ions are refined by the floating layer (compression layer), so as to achieve the best exchange effect and the best effluent quality.

Inferior regeneration

The regenerant flows through the resin layer from top to bottom. The excessive fresh regenerant contacts the strong resin of the upper pressing layer first, so that the resin layer of the effluent water quality can be fully regenerated. The regenerated waste liquid flows through the weak resin layer again, so that the regenerant can be fully utilized to achieve the best regeneration effect.

In vitro backwash (optional)

With the increase of operation period, the fine resin formed and the dirt washed out from the treated water increase. When the resistance exceeds the normal operation resistance of 0.04-0.06mpa, the resin can be transported to the backwashing tower outside the bed for backwashing to remove the fine resin and impurities. Due to the use of compressed air control washing, the effect of resin backwashing with serious pollution is the best.
