Operating rules for pure water production equipment

The operation rules of pure water production equipment, the filter element is the final barrier protection of the reverse osmosis host, and the user should replace it regularly. If there is no abnormal change in the water quality, it should be replaced at least once every half a month.

1. Operation of sand filter

During the daily use of the sand filter, since most of the suspended solids, colloids, and solid particles in the source water are filtered, this part of the dirt will continue to adhere to the middle of the sand gap due to the increase of the filtration time, blocking the flow channel of the water production, causing the water production to drop. Therefore, the user should backwash it at an appropriate time. The number of times depends on the change of the source water quality, and on this basis, it can be increased or decreased appropriately. If the water quality does not change much, it is generally enough once a day. Attention should be paid to the valves that need to be opened to prevent damage to the pump or bursting of the pipeline due to wrong opening of the valve. It is recommended that the user open the pump after confirming that it is correct. The specific operation process will be taught by our company on site.

2. Operation of activated carbon filter

The principle of this filter is similar to that of the sand filter, the difference is that it mainly filters colloids and organic matter in the source water. The operation method is the same as that of the sand filter, and the specific operation is also taught on site. In addition to the requirement of SD1<5 for reverse osmosis influent, there is another influent index for residual chlorine content <0.1mg/L.
The activated carbon filter has two functions: 1. Adsorb some organic matter in water, and the adsorption rate is about 60%. 2. Absorb residual chlorine in water. For inorganic colloids with a particle size of about 10-20 angstroms, organic colloids and soluble organic polymer impurities are difficult to remove in a multimedia filter. Under normal circumstances. Activated carbon needs to be replaced every year or so.

3. Replacement of filter element and filter element

The filter element is the final barrier protection of the reverse osmosis host. Precision filter: This fine filter has a pore size of 5um, which can effectively prevent large particles from entering the reverse osmosis membrane. The user should replace it regularly. If there is no abnormal change in the water quality, it should be replaced at least once every half a month.

4. Precautions for daily inspection

During daily inspections, users should pay attention to whether there is water leakage in the pipeline and whether the system can work normally; if there is any abnormality, they should contact the supplier.

5. the operation of the host part of the reverse osmosis

Users of reverse osmosis hosts should register the data of various instruments once a day, including conductivity meters, pressure gauges, flow meters, etc., to provide a basis for future maintenance.

6. Membrane cleaning

Under normal circumstances, the membrane is cleaned once every three months and should be operated by professionals. Before cleaning, it is recommended to notify the company 1-2 days in advance to make an appointment to teach cleaning.
