How to deal with the reduction of water production in the cycle of water treatment equipment

Method 1: Clean the membrane.

Method 2: Follow the membrane change.

Method 3: Increase the proportion of concentrated water.

1.Permeate side pressure: Under the same inlet pressure, due to the pressure holding on the permeate side or the small permeate pipeline and the long conveying point, resulting in greater resistance, the net pressure is reduced and the water yield is low.

2.Poor maintenance of pure water equipment: The operator lacks the knowledge of daily maintenance of pure water equipment, and does not carry out reasonable maintenance and maintenance of the equipment, which generally includes: regular cleaning of quartz sand, activated carbon, softened water resin, reverse osmosis membrane elements, etc., as well as regular replacement of precision filter elements.

3.Differential pressure: 6 cores of pure water equipment are equipped with 8040 membrane elements, and the pressure difference between the two stages is about 3 4 bar. Improper pipeline design leads to large pressure loss or incomplete closure of the secondary brine discharge valve, which will reduce the net pressure of the pure water equipment, resulting in low water production.

4.Instrument reading error: the pressure gauge and flow meter of pure water equipment are not corrected before use, resulting in inaccurate meter reading, and the pressure gauge is installed far away from both ends of the pressure vessel, and its reading contains the pressure loss of the pipeline, but it is used as the inlet pressure, which leads to low inlet pressure and low water production.

5.Influent conductivity (or TDS): The influent conductivity (or TDS) is much higher than the design value, and the osmotic pressure increases by about 1000ppm for every 1000ppm increase in NaCl solution TDS, and the water yield will decrease under the same inlet pressure.

Hehe! It should not be called "working water output", but the water production of the softener cycle is reduced. There are three reasons for this:

When the equipment enters the regeneration process, due to the insufficient concentration of the regeneration solution, the resin filling carrier is not fully regenerated, forming "starvation regeneration". The second is whether the height of the resin layer is reduced or the resin is polluted, so that the exchange capacity decreases. The third is whether the water pressure of the inlet water (raw water) is balanced.

All of the above can be attributed to the reduction of the periodic water production of the Hu Min Nian Control Softener.... Yijie water quality.

There are many reasons for the reduction of water production in the softener cycle, one is the problem of contamination (poisoning) of the carrier (resin) in the softener. Second, the main reason for the reduction of water production in the equipment cycle is due to the insufficient amount of salt when the equipment starts the regeneration process, and it is in a state of "starvation regeneration" for a long time. A brilliant and sparkling.

Resin crushing, poisoning, and incomplete regeneration will reduce water production.

Pure smile water touch trouble water treatment for you.

Periodic water production refers to the ability to produce how many cubic meters of qualified water can be produced in a cycle under the premise that the quality of water production reaches the qualified standard!

What are the precautions for the use of water softener equipment?

1. The water inlet of the softened water equipment should be opened for a long time when in use, unless it is the case of equipment maintenance. If no water is required, the outlet valve can be closed.

2. If the effluent is unqualified due to incomplete regeneration of softened water equipment, it can be regenerated manually.

3. When the softened water equipment is out of use for a long time, the brine needs to be sucked into the tank for protection.

4. When it is put into use again, you only need to prepare the same brine as the normal operation, open the water inlet valve first, and then connect the power supply, so that the equipment can reset itself and then manually regenerate it once to open the water outlet valve.

5. If the industrial salt used is too dirty, the salt bucket should be cleaned once a year to ensure the smooth progress of the salt absorption process.

The clean source will answer for you: is there a decrease in flow or a decrease in processing capacity. When the flow rate decreases, replace the upper and lower water distributors and the central pipe, and check whether the resin needs to be replaced. If the water output is reduced, the resin can be replaced directly.
