The current price of water purifiers for household use pure water in the thousand or so on average, more than 5,000 liters of water can be purified, approximately 300 barrels of water purification, and water purifier consumption is minimal. The dealer gave reporters calculations, "according to the current price of 300 barrels of pure water requires more than 3000 yuan, and use a water purifier manufacturing 300 barrels of water, is only 1000 yuan, and better quality." "Purified water only quality is better than tap water and bottled water, the price is cheaper than bottled water. The basic knowledge of ????? natural water sources, including surface water and groundwater, contain various impurities. water contained This is their particle size and the presence of impurities in the form of suspended matter can be divided, colloidal substances and dissolved substances into three categories., impurities in the water can be divided into inorganic, organic and microbial categories. ?? The main characteristics of the suspension is moving water in suspension, the state is still water in the light go up in weight to sink. Surface of inorganic suspended solids are mainly sand, clay or large particles and other mineral waste, a large proportion of these impurities, easy to sink organic suspended matter such as large plants, such as certain small plankton (such as algae, bacteria or protozoa) breeding wreckage and death, but also organic matter from wastewater. easy to remove weeds and other larger particles suspended solids while the smaller particles are difficult to remove. ?? natural water impurities into colloidal inorganic colloids (colloidal silicic acid, colloidal clay) and organic colloids (and other proteins and humus) two categories. characteristic of colloidal impurities in relatively stable in water and allowed to stand for a long time and will not precipitate ?? naturally dissolved substances in natural water are: to state the presence of water molecules mainly oxygen (O2), carbon dioxide (CO2) in the presence of ions in water substantially Results inorganic salts are dissolved in water, such as calcium, magnesium, iron, carbonate, sulfate, chloride, etc. was dissolved impurities impossible any mechanical method or coacervation method for removing, them stably, uniformly dispersed in the water . ?? due to natural sources of water quality and water quality requirements of users there are different levels of contradictions and gaps, so we must through advanced water purification technology, the use of scientific treatment feasible way to make natural originally contained more impurities water into living water to meet production requirements or product names:.??

By TDS tests show purified water and purified water parameters is relatively similar, it can be directly consumed. "Ordinary tap water TDS value of about 30, while the treated water purifier measured between 0 and 1." (TDS Values ??lower display more pure water quality)
