CNG Processing Equipment Regeneration Effect

In daily life, we often see the kettle with a long time after the wall will scale generation. CNG Processing Equipment What is the reason for this? Originally in our access to the water contains a lot of inorganic salts, such as calcium, magnesium and so on. These salts in the water at room temperature can not be found in the naked eye, once they are heated to boil, there are a lot of calcium, CNG Processing Equipment magnesium salt to precipitate out of carbonate, they close to the pot wall to form scale. We usually water calcium, magnesium ion content with "hardness" that the indicator. Hardness 1 degree is equivalent to 10 milligrams of calcium oxide per liter of water. Less than 8 degrees of water called soft water, higher than 17 degrees called hard water, between 8 to 17 degrees called moderate hard water. Rain, snow, river, river, lake water is soft, spring, deep well water, sea water is hard water.

The use of strong acid cationic resin in the raw water of calcium and magnesium ions replaced, CNG Processing Equipment and then by the softened water equipment filter out of the boiler water is a very low hardness of the boiler with softened water.

Work (sometimes called water, the same below), CNG Processing Equipment backwash, salt (regeneration), slow wash (replacement), fast wash five processes. All processes of different softened water equipment are very close, but only due to the actual process of different or control needs, there may be some additional process. Any sodium-based exchange of softened water equipment is based on the development of these five processes (in which fully automatic softened water equipment will increase the salt re-injection process).

Backwash: work after a period of time after the equipment will be in the upper part of the resin to intercept a lot of dirt from the raw water, the dirt removed, the ion exchange resin can be completely exposed, CNG Processing Equipment the regeneration effect can be guaranteed. The backwash process is the water from the bottom of the resin washed out from the top of the flow, so that the top of the dirt can be washed away. This process usually takes about 5-15 minutes.

Salt absorption (regeneration): the brine is injected into the process of resin tank, the traditional equipment is the use of salt pump to the salt water injection, CNG Processing Equipment automatic equipment is a dedicated built-in injector salt inhalation (as long as the water can have a certain pressure) The In the actual work process, the brine at a slower rate of flow through the resin regeneration effect than simply using salt water soaking resin effect is good, so the softened water equipment are slow to flow through the resin method of salt regeneration, CNG Processing Equipment the process generally requires 30 Minutes or so, the actual time affected by the amount of salt.

Slowly wash (replace): After brine flow through the resin, the same process with the original flow rate of salt slowly washed the process of salt called slow wash, CNG Processing Equipment because the rinse process is still a large number of functional groups Calcium and magnesium ions are exchanged by sodium ions, according to practical experience, CNG Processing Equipment this process is the main process of regeneration, so many people call this process called replacement. This process is generally the same as the time of salt absorption, that is about 30 minutes.

Quickly rinse: In order to rinse the residual salt thoroughly, CNG Processing Equipment use a flow rate close to the actual work and rinse the resin with raw water. The final effluent of this process should be a soft water. In general, the quick flushing process is 5-15 minutes.
