Basic knowledge of water treatment equipment installation and use

        Purified water equipment, softened water equipment, and ultrapure water equipment are the most common in water treatment equipment. Softened water equipment is a water treatment device that removes Ca 、 Mg ions, etc., from water to reduce water hardness and soften water. Softened water equipment has good water quality and stable system operation, and is used by many enterprises; ultrapure water equipment has good water quality and is suitable for the production needs of various enterprises, and its application range is gradually expanding.

Basic requirements for purified water equipment effluent water quality
        Purified water produced by purified water equipment is used in the pharmaceutical and biomedical industries. But what are the basic standards for purified water quality? ? Both the Chinese Pharmacopoeia and the European Pharmacopoeia clearly state that the raw water for pharmaceutical water must at least meet the standards for drinking water. If it does not meet the standards, it must be pre-treated until it meets the standards.
        In addition to Escherichia coli, which has clear regulations, other bacteria are not allowed to exceed 100 个 /ml . During the process of producing water with purified water equipment, there will also be internal pollution, and various water treatment devices in the purified water equipment may become pollution sources. Therefore, it is necessary to regularly clean and disinfect the purified water equipment. In addition, a sterilization and disinfection device should be installed at the end of the purified water equipment.

Characteristics of purified water equipment effluent water quality
        The effluent water quality of purified water equipment meets national hygiene standards and the actual production standards of enterprises. The effluent of purified water equipment - purified water has two characteristics. One characteristic is that the number of disinfection and sterilization equipment installed in purified water equipment is gradually increasing.
        Another characteristic is that the pipeline distribution system of purified water equipment is replaced by a circulating pipeline instead of the traditional water supply pipeline. These two characteristics are to control microbial contamination and the increase of bacterial endotoxins. At the same time, attention should be paid to the influence of the flow rate in the pipe on the reproduction of microorganisms, that is, if the flow rate in the pipe is too low or blocked, it may cause the reproduction of microorganisms to increase, affecting the water quality.

Key points for selecting the installation location of softened water equipment
1 、Softened water equipment should be placed as close as possible to the drainage point.
2 、If other water treatment equipment is needed, the installation location should be reserved.
3 、Because salt is frequently added to the salt tank, a salt placement location should be set.
4 、Do not install softened water equipment within 3 meters of the boiler, otherwise hot water will flow back into the softened water equipment, causing damage.
5 、The softened water equipment should be placed in an environment with a room temperature below 1 ° C and above 49 ° C 。

Precautions for using softened water equipment
After long-term use of softened water equipment, certain precautions should be followed.
1 、The inlet of the softened water equipment should be kept open during use, unless the equipment is under maintenance. If water is not needed, the outlet valve can be closed.
2 、If the effluent is unqualified due to incomplete regeneration of the softened water equipment, manual regeneration can be performed.
3 、When the softened water equipment is not used for a long time, the brine should be sucked into the tank for protection.
4 、When put back into use, just prepare the same amount of brine as normal operation, open the inlet valve first, then connect the power supply, let the equipment reset itself, and then manually regenerate it once before opening the outlet valve.
5 、If the industrial salt used is too dirty, the salt tank should be cleaned once a year to ensure the smooth progress of the salt absorption process.

Installation standards for ultrapure water equipment
1 、The equipment installation site should be chosen in a flat, clean environment, close to the power supply and water source.
2 、Do not place it near a fire source or any heating body to avoid affecting its operating efficiency due to heat.
3 、In northern areas, the equipment must not be installed outdoors to prevent the equipment from freezing and damaging the instruments and filter elements.
4 、The equipment installation location should facilitate drainage and keep the equipment's drain pipe unobstructed.
5 、The working pressure of the water pump used in the system should be ensured at 1.0-1.2Mpa to ensure that the water pump operates within its rated head range.

The working cycle of each equipment is as follows:
1 、Quartz sand filter
   Cumulative operation 2900 hours, the quartz sand filter media should be replaced.
2 、Activated carbon adsorption filter:
   When the outlet residual chlorine content > 0.1mg/L ，the activated carbon filter media should be replaced. Generally, after cumulative operation 720 hours, the activated carbon filter media should be replaced.
3 、Security filter
　　Generally, after cumulative operation 720 hours, the precision filter element should be replaced. When the precision filter is working and the outlet pressure < 0.04Mpa and the panel water shortage indicator light is on, the precision filter element should also be replaced.
4 、Reverse osmosis filter
Cumulative operation 240 hours, the RO membrane should be chemically cleaned once.
Cumulative operation 2900 hours, the RO membrane should be replaced.
Special Note: For your safety, please be sure to reliably ground the machine grounding wire.
