Water softening equipment flow chart:

Main parameters:

Water softening equipment, as the name implies, that is, to reduce the hardness of water equipment, mainly in addition to get rid of calcium and magnesium ions in the water, water softening equipment in the process of water softening, can not reduce the total salt content of water.

Because the hardness of water is mainly formed by calcium, magnesium and said, so the general use of cation exchange resins (water softeners), Ca2 +, Mg2 + (the main component of scale formation) in the water to replace out, with the increase of Ca2 +, Mg2 + within the resin, the resin removes the effectiveness of Ca2 +, Mg2 + gradually decreased.

When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated, the regeneration process is to use the salt tank in the salt water to flush the resin layer, the hardness of the resin ions in the replacement of the regeneration of the waste liquid out of the tank, the resin will restore the softening of the exchange function.

Since the hardness of water is mainly formed and expressed by calcium and magnesium since the hardness of water is mainly formed and expressed by calcium and magnesium the principle of sodium ion exchange softening treatment is to pass the raw water through the sodium cation exchange resin, so that the hardness of the components in the water, Ca2+, Mg2+, and the resin in the exchange of Na+, so as to adsorption of the water of the Ca2+, Mg2+, so that the water can be softened. If RNa represents sodium resin, the exchange process is as follows:

2RNa + Ca2+ = R2Ca + 2Na+

2RNa + Mg2+ = R2Mg + 2Na+

That is, the water passes through the sodium ion exchanger, and the Ca+ and Mg+ in the water are exchanged for Na+.

The general control valve operation process is: operation, backwash, salt absorption, slow wash, salt tank replenishment, positive wash.

1) water softening equipment workflow

Work (sometimes called water production, the same below), backwash, salt absorption (regeneration), slow rinse (replacement), fast rinse five processes. All the processes of different water softening equipment are very close to each other, only due to the actual process differences or control needs, there may be some additional processes. Any sodium ion exchange-based water softening equipment is based on the development of these five processes (which, automatic water softening equipment will increase the brine refill process).

Backwashing: work for some time after the equipment, the resin will be intercepted in the upper part of a lot of dirt brought about by the raw water, the dirt removed, the ion exchange resin in order to be fully exposed to the regeneration effect can be guaranteed. The backwashing process is that water is washed in from the bottom of the resin and out from the top, so that the dirt intercepted at the top can be washed away. This process generally takes about 5-15 minutes.

Salt suction (regeneration): the process of injecting brine into the resin tank, the traditional equipment is to use a salt pump to inject the brine, the automatic equipment is to use a special built-in injector to inhale the brine (as long as the incoming water has a certain pressure that can be). In the actual working process, the regeneration effect of brine flowing through the resin at a slower speed is better than that of simply soaking the resin with brine, so the water softening equipment is regenerated using brine flowing through the resin at a slower speed, and the process generally takes about 30 minutes, the actual time is affected by the amount of salt used.

Slow rinsing (replacement): in the brine flow through the resin, with the same flow rate of raw water to slowly rinse all the salt in the resin process is called slow rinsing, due to this rinsing process there are still a large number of functional groups on the calcium and magnesium ions by the exchange of sodium ions, according to practical experience, this process is the main process of regeneration, so many people will be called the process of replacement. This process is generally the same time as the absorption of salt, that is, about 30 minutes.

Fast rinsing: In order to rinse the residual salt thoroughly, the flow rate close to the actual work should be used to rinse the resin with raw water, and the final effluent of this process should be soft water up to standard. In general, the fast rinse process for 5-15 minutes.

Note:

1, the hardness of the inlet water＜8mmol/L, the inlet pressure of 0.2Mpa-0.6Mpa, according to the above table selection, the hardness of the outgoing water according to the requirements of the use of determination

2, inlet water hardness <8mmol/L, inlet water pressure 0.2Mpa-0.6Mpa, according to the above table selection, the hardness of the water according to the use of requirements to determine the hardness of the output water can be 0.03mmol/L: when the inlet water hardness>8mmol/L, it is recommended to use the second level of softening equipment or increase selection.

2, the rated water output exceeds the maximum configuration of the above table, you can choose more than one set of parallel use. Our company can provide the original U.S. "multi-tank connected control system" to simplify the installation of the system, high performance.

3, the cycle of water production M? = loading number of quality L / raw water hardness mmol / L
