Selection of water treatment equipment and working principle
a, the working principle of conventional water treatment equipment,
1, filter purification equipment: often used in water treatment industry using quartz sand filter, activated carbon filter, many media filters, in addition to iron and manganese filter mechanical filter, etc. There are two kinds of medium, three kinds of medium, four kinds of medium, but commonly two layer medium, more for anthracite or combination of activated carbon, quartz sand, quartz sand combination. Manganese sand and quartz sand and so on combination according to the requirements of processing water quality. Common filter materials are: anthracite coal, clay, quartz sand, activated carbon, etc. , of the several kinds of filter material, quartz sand with its density is big, small particles, low price advantage. Anthracite has its density is small, sewage capability is strong, large particles as well as the more affordable price, anthracite, quartz sand intercept and activated carbon adsorption is often used in sewage treatment and oil removal filter. Activated carbon has its density is small, in addition to flavor decolorizing ability is strong, but the price is more expensive, in commonly used in drinking water, in addition to have more effect, can improve the taste of water. But usually anthracite are seldom used in drinking water.
2, softening equipment, when the water flow by high voltage, high frequency electromagnetic field, the calcium and bicarbonate ions in the water and bicarbonate ions will be under the action of high voltage, high frequency electromagnetic field, lose the ability of chemical, physical, and attract each other, gradually formed crystals sank to the bottom, with the sewage discharge, so as to achieve the aim of anti-scaling.
3, purification equipment, water treatment equipment is used in reverse osmosis system, which USES the module on both ends of the electrode making the charged ions in the water, and cooperate with the ion exchange resin and selective resin membrane, to speed up the ion movement, thus achieve the purification of water, water resistivity can be up to 15 - - - - - - 18M。 While the hydrogen ion exchange resin regeneration roots and hydroxide with comes from under the high voltage supply by the dissociation of the water, so you don't need to use acid, alkali for regeneration.
the conventional water treatment equipment in general use in life, such as a lot of families use all kinds of hot water boiler & macr; , central air conditioning, heat exchange system, household central air conditioning, hanging pot & macr; And so on; And industry is often used in the field of water treatment equipment free press, chillers, heat exchangers, cooler, etc; The water treatment equipment and, of course, also often be used with the food, pharmaceutical, alcohol and other industries, for their equipment for antiscaling, descaling, magnetization and sterilization alga technology.
industrial water treatment equipment according to different purposes can be classified as: reverse osmosis ( Reverse osmosis) Device, ion ultrapure water device, the electric ions ( EDI) Device, the electronic industrial ultrapure water equipment ultrapure water ultrapure water equipment, pharmaceutical industry, chemical industry equipment, electric pan & macr; Supply water system, electroplating industrial ultrapure water with ultrapure water equipment, laboratory equipment, battery industry ultrapure water equipment, etc.
2, the main characteristics of type selection of water treatment equipment:
1, don't change the chemical properties of water, to the human body without any side effects.
2, descaling effect is obvious. The equipment is installed in the water cycle system, the original scale under 2 mm thick, usually 30 days or so can gradually make its mobility, after processing scale is granular, with the sewage discharge, without blocking pipe system,. Old scale off later, within a certain fan Χ no longer produces the new scale.
3, equipment, small volume, simple and convenient installation, can be used unattended for a long time.
4, water equipment, can make the water into magnetized water, and for a certain role of restrain and kill bacteria in water.
5, anti-corrosion equipment, can prolong the service life of the servo device.
