Pure water equipment is a kind of pure water produced by filtering the raw water (physical method) without adding any compound through the currently popular reverse osmosis equipment and other methods.

Pure water equipment is divided into two categories, one is living drinking water equipment, also called household pure water equipment, and the other is laboratory pure water equipment, which can meet the laboratory's requirements for pure water quality.

What is the filtration process of laboratory pure water equipment?

The laboratory pure water equipment adopts a combination of advanced reverse osmosis technology and ion exchange technology, using booster pumps, solenoid valves, high-capacity ion exchange resins, RO reverse osmosis membranes, filter elements, pipeline connections, control components, UV Products such as lamps purify water.

The functions of filter elements at all levels in laboratory pure water equipment:

The first level: pretreatment: the use of precision filters to remove large particulate matter, residual chlorine and calcium ions, magnesium ions in water to achieve the best pretreatment effect.

Second stage: reverse osmosis: reverse osmosis is the use of a high-pressure pump to provide a pressure greater than the osmotic pressure of the high-concentration solution. Water molecules will be forced to pass through the semi-permeable membrane to the side of low concentration. 99% of most pollutants including inorganic ions

Third level: Ion exchange: Ion exchange is used to remove ions. In theory, almost all ionic substances can be removed.

The fourth level: terminal treatment: mainly produces ultra-pure water of ultra-low organic type, aseptic type, non-heat source type, etc. according to the special requirements of customers.

What is the filtration process of household water dispensers?

Household pure water equipment is through five-stage filtration to reach the standard of direct raw drinking, thoroughly filtering out harmful substances such as bacteria (0.4-1 microns), viruses (0.4-0.02 microns), toxins, heavy metal ions, organic compounds, etc., while increasing the oxygen content of water The amount makes the water weakly alkaline, more suitable for human absorption, sweet and delicious.

Filter functions of household pure water equipment at all levels:

The first level: PP cotton: primary filtration of raw water to remove coarse particles of impurities, sludge, colloids, suspended substances, etc.

The second level: granular activated carbon: adsorption of odor, color, organic matter, some heavy metals, etc. in water

The third level: carbon rod activated carbon: further remove chlorine, organic compounds, different colors, odors, turbidity, etc.

Fourth level: RO reverse osmosis membrane: pore size of 0.1 nanometers, to remove bacteria, viruses, heavy metals, and other organic impurities in the water.

Fifth level: rear activated carbon: remove odor and improve taste.
