Basic knowledge of the installation and use of water treatment equipment

Purified water equipment, softened water equipment and ultra-pure water equipment are common in water treatment equipment.
water softening equipment is to remove Ca, Mg plasma in water, reduce the hardness of water, so that water softening water treatment equipment.
water quality of soft water equipment is good, the system is stable, used by many enterprises, ultra-pure water equipment water quality is good, suitable for the production needs of all types of enterprises, the scope of use will gradually expand.
purified water equipment water quality of the basic requirements of purified water equipment in medicine, biomedicine and other industries.
but what are the basic standards for purified water quality? Both the Chinese Pharmacopeia and the European Pharmacopeia have made it clear that raw water for pharmaceutical water must meet at least drinking water standards.
if they do not meet the standards, they will evolve until they meet the standards.
other bacteria are not allowed to exceed 100 /ml, except for E. coli, which is clearly defined.
in the process of water purification equipment, there will also be internal pollution, purified water equipment in a variety of water treatment devices may become a source of pollution.
so must often clean and disinfect the purified water equipment, in addition, the end of the purified water equipment should also be installed sterilization and disinfection device.
purified water equipment water quality characteristics of purified water equipment water quality in line with the national health standards, in line with the actual production standards of enterprises.
water from pure water equipment - purified water has two characteristics.
is the gradual increase in sterilization equipment installed with purified water equipment.
feature of the pipeline distribution system of purified water equipment is that the traditional water delivery lines are replaced by circulating lines, both of which are designed to control microbial contamination and the increase of bacterial endotoxins.
, we should also pay attention to the effect of the flow rate in the tube on microbial reproduction, that is, the flow rate in the pipe is too low or blocked, it may cause the reproduction of microorganisms increased, affecting water quality.
of the installation location of the softening water equipment 1, the softening water equipment should be as close to the drainage as possible.
2, if other water treatment equipment is required, the installation location should be reserved.
3, because of the regular addition of salt to the salt box, should be set the location of salt.
4, do not install the softening water equipment within 3 meters from the boiler, otherwise the hot water will flow back into the softening water equipment, causing damage.
5, the softening water equipment should be placed at room temperature below 1 degree C and above 49 degrees C.
the use of water softening water equipment after a long period of use, to follow certain precautions.
1, softening water equipment in use when the inring should be open for a long time, unless the equipment maintenance needs to be turned off.
the water valve can be closed without water.
2, if the water can be regenerated manually if the water is not fully caused by the regeneration of the softening water equipment.
3, softening water equipment in the long-term deactivation of the need to inhale salt water into the tank protection.
4, when put into use again only need to prepare and normal work of the same salt water, first open the water valve, and then connect the power supply, let the equipment reset itself and then manually regenerate once finished to open the water valve.
, if the industrial salt used is too dirty, should be cleaned once a year salt barrels to ensure the smooth progress of the salt absorption process.
ultra-pure water equipment installation standard 1, equipment installation site should be selected in a flat, clean environment, close to the power supply, water environment.
2, do not approach the source of the fire and any heating body to avoid heat affecting the efficiency of its operation.
3, in the northern region shall not be installed outdoors, in order to prevent the equipment from freezing, damage to the instrument and filter elements.
4, equipment installation location should be convenient drainage, so that the equipment drainage pipe to maintain smooth.
5, the pump pressure used in the system to ensure that 1.0-1.2Mpa, to ensure that the pump in its rated range of elevation.
work cycle of each equipment is as follows: 1, quartz sand filter cumulative work 2900 hours, quartz sand filter should be replaced.
2, activated carbon adsorption filter: when the export residual chlorine content of >0.1mg/L, should be replaced with activated carbon filter material, in general, after 720 hours of cumulative work, should be replaced with activated carbon filter material.
3, security filter in general, the cumulative work of 720 hours should be replaced with fine filter.
the fine filter element should also be replaced when the outlet pressure <0.04Mpa is at work and the panel water shortage light is on.
4, reverse osmosis filter cumulative work 240 hours, the application of drugs to clean RO membrane once.
the RO film after a cumulative 2900 hours of service.
note that for your safety, be sure to ground the machine ground wire reliably.
