The pressure drop in the tank, including resin, hardness, stuck after some time the use of the resin due to the saturation of the substrate resin with salts, etc., particles and deposits attracted a commonplace into account it comes. To relieve this issue of the revival of the resin with the right chemicals are used. However, because the sustainability of the physical good that the resin anionic A400 OH پرولایت there. compared to the other resins available in the market in the period of time during the useful life of their own, the pressure drop in the tank, including resin helps prevent.

Resin anionic A400, OH has a form of ion, OH -, and is the group عمکلردی its ammonium four triad is a kind one.

Applications of resin Purolite model A400, OH

Of the main applications of resin پرولایت A400 OH can be about the following:

1 – Remove the minerals, non-organic, in industrial applications, for the hardness of گیرهای resin, or in other words, desalination (Demineralization) from industrial water

2 – Remove silica (silica from the water)

Use cases from resin, anionic پرولایت A400 OH can be used to remove the hardness of water, desalination, prepare, pure water, and distilled water., the extraction and purification of amino acid and antibiotics, etc., purification and removal of ions, heavy metals, and… noted.

There is silica in the water, on industrial facilities, what impact there?

Removal of silica from water used in industrial applications, in time, the use of boiler steam importance, the more there is. The effects of silica on the pipes, turbines, steam and other utilities are clearly marked. Especially in applications that to save costs, the pressure of the steam in its brand. harms, and the evil effects of silica, more determined, and it appears.

There is silica in the water, boilers, many problems are brought. Sediment derived from the silica is very hard and sticky, and is the removal of deposits on utilities and pipes is very difficult. In addition, deposits of silica in the water boiler and cause a sharp drop in heat transfer and thus increase the energy consumption can be.

One of the best methods for removal of silica from water, the use of resin ion exchange is, for this can be the beginning cation existing in water using a cationic resin is removed and then using a sample of strong resin anionic silica for silica from the water removed.

The benefits of resin, anionic پرولایت model A400, OH

1 – the operational capacity up to remove hardness of water

2 – the performance of kinetics (Kinetic), the good and the exchange capacity of the high

3 – sustainability of the physical, chemical and high thermal

4 – the ability to revive the effective and efficient

5 – lifetime high

The revival of the resin, anionic A400 OH پرولایت

After a while, the use of resin, etc., due to the absorption of salts, etc. sediments and particles in the water, the bed of the resin inside the cavity filter with this material is saturated, and other performance will be, etc. resulting in loss of pressure inside the tank, the device hardly stuck, there comes.

For this is that the resin in the long-term performance of your progress. need that after saturation of the resin, it revived. For the revival of the resin پرولایت A400OH with the form hydroxide (-OH) of sodium hydroxide (L NaOH) is used. For the same purpose. a solution of sodium hydroxide with a concentration of 3 to 6 percent rate of 2 to 4 cubic meters per hour U.S. resin for 30 to 60 minutes from the resin bed pass up. It should be noted that the resin A400OH, to the resin, the type a (model A600) that the structure of the آمونیومی based on polystyrene were. to caustic soda less for rehabilitation needs. The addition of sodium hydroxide of potash (KOH) also can be used to revive the resin آنیونیA400OH use that; but potash prices higher, there is.

Pressure drop (Pressure Drop): after some time of start of use of the system, tough-taker, because of the saturation of a bed of the resin inside the filter might drop the pressure inside the tank there is. This pressure drop function of several factors, such as: particle size distribution, etc. the depth of the resin bed, the volume of material exchange, etc., the flow rate and the viscosity (viscosity) solution of the infiltrators can be. Factors affecting any of the cases expressed include the following:

• Increased sediment particles on the bed of the resin
• Compression too resin
• Incorrect classification and non-normative or incomplete resin bed

Due to factors such as water quality, input, application, device hardly stuck, and the parameters of the design of it, Dubai incoming water or the flow rate can be from 10 to 40 barrels per hour (BV/h) variable.Wash reverse (Backwash): during Beck wash up. the tank contains the resin should be for 10 to 15 minutes, with a volume equivalent to 50 to 70% of the total volume of the tank be rinsed. Operations Beck wash makes the … particles, which in a bed of the resin inside the tank have been trapped in. and bubbles are trapped inside the resin bed is also out. After this operation, resin particles to the at least their resistance to the arrival of the flow of water to arrive.
Note: in the first service after installing the device, the hardness of the washing time of 30 minutes is recommended. Volume of the resin bed with the increase of flow velocity increase and decrease the temperature of the fluid input is reduced.
Be careful when you wash the reverse because of the pressure, and expansion over the limit. the resin inside the tank to the pipe high tank leaking.
The revival of the resin, anionic strong (SBA), such as resin, A400, OH پرولایت only with the use of chemicals has the strong base is possible. Soda ash (L NaOH), almost always as a regenerative strong anionic for the rehabilitation and reconstruction of resin anionic used. Potash سوزآور (KOH) can also be used for this purpose used, but its price relative to the caustic soda is high.

Steps to revive an ion-exchange resin

Methods for the revival of the resin, water treatment (an ion-exchange resin)

The direction of the revival of an ion-exchange resin with the use of chemicals, appropriate, the general steps below have to arrange to be done:

1 – Beck pipelines: (Bakwash) water from the top of the tank on the resin bed inside it poured. By passing a stream of water from among a bed of the resin, etc. suspended solids remaining in the world, deleted and resin beads, again, on the surface of the tank, the distribution can be. Increase the volume of the resin bed by passing the water that makes any fine particles and sediments from the resin bed, remove the back.

2 – regenerative injection (Regenerant injection) : in this stage, the solution revived for a time insufficient contact with the resin, with the flow rate down to the column of ion exchange is injected. For resin mixing, bad, etc. the process of rehabilitation complex is more, and this is done that the first resin apart can be, then, to the order of a substance regenerative سوزآور or some kind of regenerative acid can be used.

3 – replacement regenerative (Regenerant displacement) : regenerative for gradual use the flow of water (to dilute), with the same speed the flow of a solution of regenerative out tank driven. For units of the resin mix, bad, etc. after using the solution, regenerative, etc. replacing materials of the contaminants in the resin bed with article regenerative happen and resin with air and nitrogen, compressed composition can be. The flow rate of this stage is to step it up“, shower, slow,” say, to avoid damage to the resin beads must be carefully managed.

4 – wash: (Rinse)finally, the resin of a current similar flow rates, cycle service, washed with water can be. Wash cycle should be as long as the water to the level of quality desired, and the desired time. continue find.

The useful life of the resin پرولایت A400OH

Resin anionic A400OH, if properly maintained, and the revival of timely during lifes in about 5 – 6 years. In the event that the resin quality is appropriate, and is from the municipal water feed, this duration can be increased.
