  Problems to be paid attention to in the use of water treatment resin.

 

1, backwash loss

If the backwash flow is too large or the backwash operation is abnormal, resin loss will occur, and a large amount of resin is often found in ditches and wastewater ponds.

 

2, the flow through part is damaged

Resin leakage from the equipment, into the rear equipment or water supply system, resulting in the operation of the rear equipment, water quality deterioration.

 

3, the resin layer is not clear

For example, mixed bed requires two kinds of resin can be stratified well, otherwise it will reduce the amount of water and effluent quality. In severe cases, the water will not reach the required index.

 

4, turbidity of the pollution of Yang resin

When the turbidity of influent exceeds the requirement or precipitation occurs in DC condensation, more suspended matter enters the first stage ion exchanger, the phenomenon of resin pollution will occur. These suspensions often contain coagulants, typically salts of high-priced metal ions.

 

5, calcium sulfate precipitation

When using sulfuric acid to regenerate the resin, if the concentration of sulfuric acid is too high and the flow rate is too slow, calcium sulfate will deposit on the surface of the resin particles, resulting in hardness of the water. At this time available hydrochloric acid regeneration, will deposit sulfuric acid to dissolve, or in time with a large amount of water flushing.

 

6, iron pollution Yang, Yin resin have been polluted, but the two kinds of resin iron pollution mechanism is not the same. In the first stage of desalting equipment, Yang resin is in contact with raw water neutralizing iron ions, iron condensed products and corrosion products. After the iron ion in water is absorbed by the positive resin, it is difficult to regenerate, and the corrosion product turns into iron ion during regeneration. At a lower regeneration dose, it will also be absorbed by the resin at the effluent end. Iron ion pollution will make the color darker, accelerate oxidative degradation, gradually reduce the performance of water quality deterioration and reduce the amount of water; Negative resin by iron pollution is different, often by the regeneration liquid into the iron deposition on the negative resin, and silicon, organic matter and other combined into a complex material form to make the negative resin is polluted, and this pollution is cumulative.

 

7, colloidal silicon

Colloidal silicon is a phenomenon caused by improper regeneration of strong alkali negative resin. When the ratio of silicon dioxide to strong acid anion in raw water is large or weak base negative resin absorbs strong acid in water, colloidal silicon may be formed in the regeneration of negative resin. This phenomenon is more likely to occur when the concentration of lye is higher and the temperature and flow rate are lower.

 

8. Organic pollution

Organic pollution resin is the main problem in water treatment. As the pollution of natural water becomes more and more serious, the pollution of resin brings great threat to water treatment. The stronger the alkalinity of resin, the more serious the pollution degree of organic matter, the higher the ratio of organic matter and strong acid anion in influent water, the greater the pollution degree of resin.
