Industrial pure water equipment requires maintenance and upkeep after a certain period of use. How should it be maintained specifically? Why does pure water equipment flow dirty water and wastewater when in use?

How to maintain industrial pure water equipment?

1、 Timely sampling and inspection of water samples

1. Sand filter: Check the turbidity of the water output by 5NTU

2. Carbon filter: Check that the residual chlorine content in the water output is less than 0.1PPM

3. Softener: Inspection strength ＜ 30mg/l

4. Security filter: Inspection SDI ＜ 5

5. RO reverse osmosis: Check the moisture content of microbial strains in leaking water, purified water, and concentrated water

2、 Record the main operating parameters of the machinery and equipment on time

1. Inspection results for each stage and period

2. Sand filtration, carbon filtration, softening, security personnel filtering import and export trade, working pressure before and after the pump, each section, second section, etc

3. Electrical conductivity of source water and purified water at different stages

4. Under the same working pressure, the total flow rate of purified water and concentrated water, as well as the conductivity of purified water

3、 Record each maintenance result

1. The time and total number of raw material disassembly and replacement

2. Based on the main operating parameters, the time and results of cleaning the membrane

3. Damage and maintenance results of each spare part

4、 Filter element

Pay attention to immediately replace the filter element. Avoid clogging of the filter element or environmental pollution, which may harm the actual effectiveness of the preparatory treatment.

5、 Common faults

If there are common faults, they should be dealt with immediately. During the operation of industrial pure water equipment, if any abnormalities occur, immediate maintenance and upkeep should be carried out to prevent small problems from turning into troubles.

6、 RO reverse osmosis membrane

The RO reverse osmosis membrane must be cleaned immediately. Normally, the machine equipment will automatically clean the RO reverse osmosis membrane, and some unique situations require manual cleaning. During the cleaning period, the RO reverse osmosis membrane components do not produce water, allowing the cleaning water to flow at a high speed along the parallel surface of the pulse damper, thoroughly removing air pollutants accumulated on the membrane surface from the system software, completely eliminating the growth of bacteria in the pipeline, and improving the quality of RO reverse osmosis water output.

7、 No unauthorized adjustment

There is no need to adjust the wastewater ratio, pressure, and other gate valves without authorization. Each model and specification of industrial pure water equipment often has a matching main parameter range. Another option is to set it properly after installation, depending on the natural environment of the application. Unauthorized adjustment can reduce the service life of the filter element or cause common malfunctions in industrial pure water equipment.

Why does pure water equipment flow dirty water and wastewater?

Most of the real and practical water purification products will cause wastewater. It is unlikely that a water purifier will not cause wastewater, so come up with a solution: as much water as enters, so much water as exits, which can have certain practical effects. Therefore, installing a water purifier inevitably causes some wastewater.
