380V Reverse Osmosis System Brackish Water Treatment Plant With CE Certification
First, the pretreatment system is washing and backwashing is the first step of equipment purification.
1. Large-capacity equipment is equipped with a multi-media filter, an activated carbon filter, and a softened resin filter (optional). Through the
forward and reverse flushing of the pretreatment system, the raw water quality can be more easily reached to the influent standard of pure
water, and the normal life of the reverse osmosis membrane is guaranteed. In daily use and maintenance, regular positive and negative rinsing
operations can remove impurities and impurities remaining in each filter. In addition, activated carbon filtration is mainly used to remove free
chlorine, color, microorganisms, organic matter and some heavy metals and other harmful substances in water. Prevent them from affecting the
reverse osmosis membrane system. Because the activated carbon filter will retain most of the organic matter and impurities, it is a breeding
ground for bacteria. Therefore, it is necessary to periodically replace the activated carbon filter material in it. The softening resin is a special
resin for softening hard water, and the hardness of water is lowered by ion exchange technology. When the soft water resin replaces a certain
amount of hardness ions such as calcium and magnesium in water, it will not be able to soften the water. At this time, it is necessary to soften
the filter for resin regeneration. For normal regeneration, it is necessary to ensure sufficient salt and water in the salt tank. . In addition, a scale
inhibitor dosing device can be selected, and a scale inhibitor is added to the reverse osmosis water to prevent the insoluble salts such as
calcium carbonate, magnesium carbonate and calcium sulfate in the reverse osmosis concentrated water from being concentrated, and the
scale precipitates to block the reverse osmosis membrane, thereby Guarantee the life of the membrane components.
2. Equipment with small processing capacity is equipped with a filter element as a pretreatment filter. Generally, there are PP,
etc., and it is only necessary to replace it according to the quality of the raw water.
3. The reverse osmosis membrane will be automatically cleaned during the normal operation of the equipment, and daily use
only needs to be replaced regularly.
Second, it is necessary to pay special attention to: the equipment pressure (inlet water pressure, working pressure) must meet the standard,
otherwise it will easily cause the equipment to have insufficient water output, and the equipment air consumption will easily cause equipment damage.
Third, for equipment equipped with precision filters, it is necessary to replace the filter element regularly to ensure the quality of water in the equipment. When the pure water equipment stops running, it must be cut off and power off, and the security facilities should be completed.
4. Regularly monitor the quality of the produced water.
If the water conductivity (or TDS value) of the equipment is higher than our standard value, the production of water should be stopped and the
reverse osmosis membrane should be cleaned or replaced.
The daily maintenance precautions for pure water equipment have the following points:
1. Be careful to replace the filter element in time. Now people's health awareness is getting stronger and stronger, and the requirements for
water quality are getting higher and higher. The filter elements of pure water equipment must be replaced in time to ensure water quality and
ensure the taste of water.
2. A fault is resolved in time. In the process of running pure water equipment, if there is a fault, it should be repaired and maintained in time to
avoid minor problems becoming big troubles.
3. The reverse osmosis membrane needs to be cleaned in time. Under normal circumstances, the equipment will automatically clean the
reverse osmosis membrane, and manual cleaning is required in some special cases. During the cleaning, the reverse osmosis membrane
element does not produce water, so that the cleaning water flows along the surface of the diaphragm at a high speed, and the pollutants
deposited on the surface of the membrane are completely washed out of the system, completely eliminating the possibility of breeding bacteria
in the pipeline, and improving the effluent of the reverse osmosis water. quality.
4. Do not arbitrarily adjust the valve ratio, working pressure and other valves. Each type of equipment has a corresponding parameter range. In
addition, depending on the environment, it will be set after installation. Unauthorized adjustment can result in reduced filter life or equipment
failure.
