Water treatment equipment is generally well understood, wastewater treatment is to deal with wastewater, electroplating wastewater treatment is to deal with electroplating wastewater. But in water treatment, pure water equipment, purified water equipment, ultrapure water equipment three kinds of equipment silly. Many people think that pure water and purified water equipment is the same, just an abbreviation of a whole process. Most people have a certain understanding of pure water equipment and ultrapure water equipment, but the three put together is completely baffled. Today, the science of pure water equipment, water purification equipment, ultrapure water equipment, the main difference and water quality respectively.
What are the main differences between pure water equipment, water purification equipment, ultrapure water equipment?Applications:
Pure water equipment is mainly used in the field of food and drinking water
Purified water equipment is mainly used in the field of medicine.
Ultra-pure water equipment is mainly used in the field of electronics industry, semiconductor, optics, glass and other fields.
Inlet water quality:
The inlet water quality of water purification equipment is generally tap water.
Water purification equipment and ultrapure water equipment is mainly pure water, so water purification equipment and ultrapure water equipment are based on pure water equipment to increase the water quality purification process.
What is the difference between the resistivity standards of the three types of equipment?1. Pure water resistivity 0.1 × 10^6Ω-cm (ohm-cm) (25 ℃, distilled water test data, theoretically pure water is not conductive);
2. Ultrapure water resistivity 10MΩ * cm (25 ℃). Resistivity in the working temperature of 25 ℃, the highest theoretical value can reach 18.3MΩ?cm. actual ultrapure water equipment produced water online test the highest value is 18.2MΩ?cm.
3. purified water resistivity ≥ 0.5MΩ.CM (25 degrees Celsius). For injections, eye drops container rinse with purified water resistivity should be ≥ 1MΩ.CM/25 degrees Celsius.
Note: 15MΩ * cm (25 ° C) means: a temperature, the side length of 1CM cube of water between the relative sides of the resistance of more than equal to 15 ohms.
In fact, these three types of equipment is mainly designed for three different water quality, so the main difference lies in the water quality is different, pure water is mainly drinking water, purified water is the medical aspects of water: divided into water for injection and medical purified water. Ultra-pure water is mainly to water purity standards, water in addition to hydrogen and oxygen almost no other atoms of water, characterized by pure enough.
